Deploying E20

www.cisco.com

Cisco IP Video Phone E20 Administrator guide

D14 330 .12 Adminis trator gui de Cisco IP Video Pho ne E20, TE4.1 Novembe r 2011.

Deploying the E20

There are four ways of deploying the E20:

• By use of automatic provisioning.

• By use of the keypad.

• By logging into the unit from a remote PC.

• By use of Provisioning.

Automatic provisioning

When you start the E20 the rst time you will be prompted to choose the language to be used in the menus and dialog boxes.

Once the language has been selected, the E20 will congure the correct language and a provisioning assistant will pop up.

The wizard will help you congure the E20 with the correct parameters. Observe that Cisco has dened a set of DHCP options. The E20 will pick up these settings if they have been set by your network administrator.

The wizard supports dierent provisioning or conguration schemes. The Cisco VCS (TMS 12.5) is the default scheme and is the recommended provisioning scheme for the E20. The other schemes will only allow the E20 to be easily congured using a core set of conguration parameters. The E20 suppor ts VCS, Broadsoft, Cisco Callway, Cisco UCM and HT TP. Callway is a subscription based service. Contact your Callway representative for more on this. Depending on the infrastructure you will be prompted to supply information like username and passwords.

Once you have completed the elds and selected the register button, the E20 will contact the external manager and tr y to provision the device. You will be notied whether the registration process succeeds or fails. Note that even if provisioning or registration fails the system may keep trying in the background

In case of failure to connect successfully, you may rectify the parameters and try again. If you don’t have provisioning set up in your network you can choose Manual to congure basic SIP settings manually. You can run the Startup wizard later using the menu.

The nal step of the wizard will be to adjust the camera. Note that camera adjustment is optional at this stage—you may choose to do this later.

Using the keypad to congure the E20

1. Navigate from the Home menu to the Menu tab. Use the Down arrow key to

navigate down to Advanced settings. Press .

2. Navigate down to System conguration and press

3. Navigate to SystemUnit > Name and press

Select a name that is unique to avoid conicts. We recommend that you use your name or initials, eg. AliceWonderland. This name will be seen as you by the others.

4. In most cases DHCP will be used for assignment, this is the default setting.

To set to static, go one step back and up to IP Settings > IP Assignment. Set to

Static. Enter the IP address, Subnet Mask and Gateway IP address.

5. To set provisional parameters go to Provisioning > External manager.

In most cases when you change settings in the Provisioning submenu, the E20 will send a provisioning request to the external manager. More on this can be found in the “Auto provisioning” on page 8.

6. In case you are not going to use an external manager, there are things that need to be

congured manually:

a. To be able to dial, you need to congure the SIP settings. In the

NetworkServices > SIP, set SIP Mode to O before doing anything else.

b. Go to SIP > Prole1. Set Default Transport to Auto (which is the same as

default), Proxy1 Discovery to Manual, You must also enter the IP address of the Proxy (Proxy is your PBX/VCS or OCS) and you must enter the URI of your E20. Set the SIP Mode back to On.

c. If your SIP Server / PBX uses user authorization you need to supply a user-id and

password. This is done in SIP > Prole1 > Authentication 1.

d. You may want to use a TMS phonebook. If you have this and no entries are

displayed after conguring, you must make sure that your unit is registered in TMS and that a phonebook is assigned to your system.

Your E20 comes with no default administrator password set! This means that anyone with network access to the E20 can easily log onto the device with SSH.

We strongly recommend that you set up an administrator password by using the menu in Settings > Advanced > Change password.

www.cisco.com

Cisco IP Video Phone E20 Administrator guide

D14 330 .12 Adminis trator gui de Cisco IP Video Pho ne E20, TE4.1 Novembe r 2011.

Setting up the E20 from a remote PC

Log onto the system using Telnet or a SSH client. When using SSH log in with username “admin”.

First you should choose a name for your unit. Use a name that is unique to avoid conicts. The recommendation would be to incorporate your name or initials, eg. AliceWonderland.

xCongu ration SystemUnit Name: “AliceWonderland

”

Note that in most most cases DHCP will be used for assignment:

xCongu ration Network 1 Protocol: “IPv4”

xCongu ration Network 1 Assignment: “DHCP”

If not, you may want to set your IP network settings manually:

xCongu ration Network 1 IPv4 Address: “<Your-IP-Address>”

xCongu ration Network 1 IPv4 Gateway: “<Network-Gateway-IPAd dress>”

xCongu ration Network 1 IPv4 Subnetmask: “<SubNet-mask>”

xCongu ration Network 1 DNS Domain Na me: “<local dom ain names>” xCongu ration Network 1 DNS Server 1 Address: “<DNS Server IP Address>”

For remote administration the following settings are recommended. This should also make the system visible in TMS.

xCongu ration Provisioning Mode: Tms

xCongu ration Provisioning ExternalManager Address: “<hostname of your tms server>”

xCongu ration Provisioning ExternalManager Protocol: Http

xCongu ration Provisioning ExternalManager Path: “tms/public/ external/managem ent/systemm anagementservice.asmx”

To be able to dial, you need to congure the SIP settings.

xCongu ration NetworkServices SIP Mode: On

xCongu ration SIP Prole 1 DefaultTransport: Auto

xCongu ration SIP Prole 1 Type: Auto

xCongu ration SIP Prole 1 Proxy 1 Discovery: Manual

xCongu ration SIP Prole 1 Proxy 1 Address: “<ip of your SIP server>”

xCongu ration SIP Prole 1 URI: “<your SIP URI>”

If your SIP Server/PBX uses user authorization you need to supply a user-id and password

xCongu ration SIP Prole 1 Authentication 1 LoginNam e: <your user-name>

xCongu ration SIP Prole 1 Authentication 1 Password: <password>

You may want to use a corporate TMS phonebook. If you have this and no entries are displayed after conguring, you must make sure that your unit is registered in TMS and a phonebook is assigned to your system.

xCongu ration Phonebook Server 1 ID: “default”

xCongu ration Phonebook Server 1 Type: “TMS”

xCongu ration Phonebook Server 1 URL: “<URL to your phonebook ser v ic e>”

Should the system fail to respond to incoming calls, make sure that:

• The system is connected to line voltage

• The LAN cable is properly connected—see Connecting the E20 for details.

Auto provisioning

There are situations where service providers prefer that users need not enter any information at all. Instead, they want the E20 to retrieve all the information necessary by itself—through pro-active behavior using HTTP or HT TPS.

When provisioning mode is set to Auto (default), we try the following:

1. HTTP provisioning towards http://tandbergprovisioning/getcong

2. If PROVISIONINGSERVER and PROVISIONINGDOMAIN is set in /etc/dhcpinfo,

use VCS provisioning

3. If TMSSERVER is set in /etc/dhcpinfo, use TMS provisioning

4. For TE4.0 and newer: If TFTPSERVERADDRESS (option 150) is set in /etc/

dhcpinfo, use Cisco UCM provisioning.

5. If TFTPSERVER (option 66) is set in /etc/dhcpinfo, try tftp

6. HTTP provisioning towards http://globalprovisioning.tandberg.com/getcong

(see examples right).

If all of the above steps fail, the GUI will show the startup wizard.

With TE4.1.0 the E20 supports provisioning and basic call functionality with Cisco Unied Communications Manager (CUCM) version 8.5 and above. The E20 also supports Cisco Discover y Protocol (CDP) for easy deployment in CUCM environments. Voice VLAN and Data VLAN are VL AN tags used by Cisco switches. When provisioning mode is set to CUCM in the Start Wizard, the E20 will try to use Voice VLAN if available in your network. When in other provisioning modes the E20 will try to use Data VLAN. See also the appendix for more on this.

Adding entries to My contacts

You may add new contacts to My Contacts. Entries in other folders, such as the

corporate director y must be made by your system administrator.

Adding entries manually

It may happen that the list of My contacts grows large on your system. You may therefore promote those entries you call the most to a shortlist to make them easier to locate. This shor tlist is called Favorites. The Favorites list is a subset of My contacts—you cannot be someone’s favorite without being a member of that person’s My contacts already.

Do as follows:

1. Navigate to the Directory tab.

2. Navigate to Add new contact and press

3. Press again:

4. Enter Name and Number/URI of the new contact. If you want the entry to

also appear on the Favorites short list, make sure Favorite is set to Yes .

5. Navigate down to Save and press

to save the the new contact, or navigate

to Cancel and press

to leave the menu without saving the new contact.

Save will appear ghosted until there is something to save.

Copying entries from the corporate directory

You may also copy entries to My contacts from the corporate directory. Note

that once copied to My contacts, these entries will loose their connection to the corporate directory. This means that any updates of the corporate directory will not be reected in My contacts. You will have to update the My contacts manually.

Do as follows:

1. Locate the entry in the corporate directory and press

. This will produce the

following dialog box:

Hedda Ga bler (SIP)

hedda.gabler@company.cu.zk

2. Navigate down to Add to favorites to add this entry. The entry will become

member of My contacts, since it is now among the favorites.

If you want this entry to be just a common member of My contacts and not among the favorites, you may remove the entry from the Favorite list (while still retaining it in My contacts)—see the following page for details on this.

www.cisco.com

Cisco IP Video Phone E20 Administrator guide

D14 330 .12 Adminis trator gui de Cisco IP Video Pho ne E20, TE4.1 Novembe r 2011.

Removing an entry from the list of Favorites

You may remove an entry from the Favorites list without removing the entry from

My contacts.

Do as follows:

1. In the Home menu navigate down to the entr y to be removed and press

The below dialog box will now be displayed.

norah dollhouse

norah.dollhouse@somewhere.com Online

2. Navigate down to Remove from favorites as shown and press . The entry

will now be removed form the Favorites list, but it will remain in the list of My contacts.

Removing an entry from My contacts

You may remove entries from the My contacts list. These will then be removed

permanently.

Do as follows:

1. Use the

buttons to navigate to the Directory tab and then down to My

contacts. Press .

2. Locate the entry to be permanently deleted and press the C button. The

following dialog will appear:

3. Select OK and press to exit the menu putting changes into eect or

Cancel to exit menu undoing any changes.

Switching between two calls

When you are in a call you may put the other party on hold while you call someone else. You will then be in call with two par ties, but only one at a time.

Do as follows:

1. While in a call, press the softkey Hold. The softbuttons will now change to

show you two options:

• Resume to go back the call you were in.

• New call to let you call someone else, while at the same time keeping the

rst part y on hold.

2. By using the softbutton that will toggle between Hold and Resume you may

switch between talking to either par ty.

Blind transfer

When you are in a call, you may transfer the other party to someone else, to let them communicate without your participation.

Do as follows:

1. While in a call, press the softbutton Tr ans fer. The Softbutton menu will give

you two options, viz. to transfer the one on hold or This will bring up the following menu:

norah dollhouse

peer gynt

hjalmar ekdahl

hedwig ekdal

emma bova ry

oscar w. ild e

2. You may now key in the number/URI to which the other party shall be

transferred. Alternatively, you may use the Favorites or Frequently called. Or you may navigate to the Directory tab and place your call from there.

www.cisco.com

Cisco IP Video Phone E20 Administrator guide

D14 330 .12 Adminis trator gui de Cisco IP Video Pho ne E20, TE4.1 Novembe r 2011.

3. Af ter the number/URI has been located, proceed as if you were placing a

call from the phone book in the usual way. The only dierence is that the other party will be connected to the one you just called and you will be disconnected.

Consultative transfer

You may also combine the two above options. Instead of just transferring the

other party to someone else without consulting the one to receive the call, you may call this person rst and then do the transfer.

Do as follows:

1. While in a call, press the softkey Hold.

2. Press the softbutton New call and place a new call in the usual way.

3. Press Trans fer. You will now be prompted to decide whether this new call

shall be transferred to the one you have on Hold or as a blind transfer to someone else (the option Other).

Video conferencing using MultiWay™

The E20 supports MultiWay™ as a means to call more than one. Successful use

of MultiWay requires the presence of certain infrastructure products.

Note! MultiWayConference of Prol e1 (see “Prole 1–3” on page 28) must

have been set to the correct address of the MultiWay server to make this work.

This must be set for Prole 1 regardless of which Prole(s) that actually are in

use. The other Proles need not be specied for MultiWay to make this work.

Cas e 1: Assume that you already are in a call and that you would like to expand

the call to include someone else.

Do as follows:

1. Start calling someone else by pressing the

. This will produce the menus

allowing you to place a call as described earlier.

2. Placing a new call will put the current call on Hold. When the new participant

replies, select Join Calls.

3. Repeat, if needed, to include more participants.

Each participant may leave the conference at all times by terminating the call in the usual manner. This will disconnect the par ticipant, but the rest of the conference will go on.

If the one who initiated the conference terminates his or her call, the conference may be brought to an end (all participants will be disconnected) or the conference may go on without the initiator. This will depend on the actual setup of the MultiWay server. Consult your System Administrator, if needed, to nd out more about this,

Case 2: Someone calls you while you are in a call. You will need to decide

whether the calling party shall be invited to join the current call or not.

1. Someone calls you while you are in a call. A dialog box giving you three

options will be shown. The options are:

• Accept (put current call on hold)

• Accept (disconnect current call)

• Reject

2. Select Accept (put current call on hold).

3. When you are ready to create the conference, select Join Calls.

Case 2 options: If you do not want to set up a MultiWay conference, you have

the following choices in 2. above:

• If you want to accept the incoming call instead of the current call, select

Accept (disconnect current call).

• If you do not want to respond to the incoming call, select Reject.

Note! The maximum number of participants in a MultiWay call is limited by the

capabilities of the infrastructure of your network only. The two cases described on this page may be combined as much as you want.

Note! You may not invite an ongoing conference to the Multiway. If one of your

participants is a conference or a multisite call the Join button will be disabled.

Adding the screensaver of your choice

You may add the screensaver of your choice to the E20. You will need a USB

disk containing the picture(s) you want to use as screensaver. If the USB stick contains multiple pictures, the contents will be shown as a gallery, one picture at a time.

A few things to observe:

• Once you have plugged in the USB disk, the E20 will produce a dialog

asking you whether the pictures on the USB disk should be displayed by the USB picture frame. TE 4 will read xcif data and even rotate images when necessary. The prompt will let you specify the time interval between the last time you operated (used) the E20 and when the screensaver should start to appear.

• The USB disk must remain connected to the E20 to make this work.

• The following le formats are supported: *.jpg, *.png, *.gif.

The E20 uses Exif information to scale the picture.

Avoiding conict with the standby function

There is a standby function in the E20. When activated, the standby function

makes the screen go black after a time interval (delay) specied by you. This

setting will override the screensaver feature. To continuously display the screensaver, the standby function must be disabled. You may, however, combine the two. Consider the following: Assume that you specify the screensaver to start after 10 minutes and that you

specify the standby to start after one hour. Five minutes after the last time you

used your E20 (or pushed any button), the screensaver will start and it will then

run for 55 minutes until the standby function starts.

Multiple lines

TE 4 supports multiple lines. This means that it supports registration of multiple

concurrent SIP proles on the E20. Consequently, it is possible to be registered with more than one Address-Of-Record at the same time. The user can be reached through several SIP URIs at the same time and it is possible to call using a specied SIP prole. One example would be the use of a work (SIP-) prole for the home oce and a private (SIP-)prole. Another example would be a secretary using both a personal (SIP-)prole and the (SIP-)prole for his/ her manager.

Limitations:

• In general, it is not possible to use dierent lines to dierent types of SIP

servers (for example Cisco VCS vs Broadsoft Broadworks).

• Multiple lines is not currently supported when registered to Cisco UCM as a

native device.

When dialing out from a system congured with multiple lines, you will need to select a line before making the call. The line currently selected is shown above the Search or dial eld. Navigate to this eld and press

The available lines will then be shown as outlined below.

Select your line and dial as usual.

Incoming calls with multiple lines

In the Advanced settings you may dene how the E20 will respond to an incom-

ing call. This is called IncomingCallAlertLevel. This feature may come in handy

when the E20 is set up in shared lines enviroments. You may select between

Discreet, Regular and Silent. The setting may be set separately for Idle and

In-call situations. Note that access to Advanced settings may have been pass-

word protected by the system administrator.

When your unit has been congured with multiple lines you may, of course,

receive more than one call as well.

If you are in a call and another call comes in, the response will be in accordance

with the alert level setting. If this is set to Silent the only indication will be along

the bottom line of the screen as outlined below.

If set to Discreet, it will appear as outlined below.

In both cases press the key corresponding to the center softbutton to open the

menu and then navigate down to the incoming call:

Press to gain access to the options:

Navigate to make your choice and press to put your choice into eect.

If the alert level has been set to Regular, another incoming call will appear as outlined below. Use the

and the to make your choices.

You may have put several incoming calls on hold. An example is shown below.

Press Press to gain access to the options:

Navigate to the one to resume communication with and press . Press again to put your choice into eect.

If your E20 is hooked up to Multiway, you may resume more than one call and thereby initiate a video conference (some of the participants may be audio only, but they may still par ticipate in the conference).

Shared lines

The Cisco Unied Communications Manager (CUCM) allows several devices to

share the same number. This enables remote resume and barge in. The CUCM documentation provides the details on how to set up shared lines. Assume that you share a number with someone else and that person has put a call

on hold. Remote resume means that you may resume this call from your E20. You may also Barge in to an ongoing call (merge into the call) on a shared line,

as outlined below.

Broadworks Specic Features

TE 4 supports BroadWorks which is a software-based IP-PBX. You may provision

the E20 using the BroadWorks provisioning system. In addition to supporting the BroadWorks provisioning scheme, TE 4 supports Shared Call Appearance, Clickto-dial, Push-to-talk. The former is a concept based on support for private and shared lines. Private lines are regular SIP-proles similar to the line concept in TE

2.0 and earlier versions. A shared line is a BroadWorks extension supported in TE 2.1 and higher. It means

that several users (E20s) can share a single line.

Whenever someone calls the shared line, all of the E20s congured with this

shared line will start to ring. Whoever answers rst will take the call. However, it is possible for other users of the shared line to barge-in and join the call.

Since Broadworks does not suppor t video mixing in its current version, the joined

call will be audio only. As soon as one of the users disconnects from the call, the

video will be resumed.

It is also possible for one operator to put a shared line on hold and let another operator resume the same shared call on another E20.

Click-to-dial is a concept where a web-based call-control manager can be used to set up and tear down video calls between dierent devices. The most common use case would be for a user to call another user from his/her own E20.

Push-to-talk is a concept similar to a walkie-talkie where the calling user will press the call button to immediately be connected to the remote party.

The Settings

Applications

There are a few applications not related to video communication as such included with your E20. Actual contents may be countr y-dependent.

My shortcuts

With My shortcuts you may redene one or more of the softbuttons appearing along the bottom line of the display. There are three sets of options to choose from:

• Speed dial lets you assign one of your phone book entries (including My

contacts) to a softbutton.

• Menu shortcuts can be used to save you from menu navigation by having a

menu item available at the push of a softkey. Choose between Applications,

Call settings, Move camera, Make a call, Phone book and System information. The one you assign to a particular softbutton will you take you

to that menu when you push the corresponding button. What these menus actually do will be explained later in this part of the guide.

• Actions can be Redial or USB media.

To utilize this feature, navigate to a softbutton and press

to enter the options list. If you have assigned one or more softbuttons and enter this menu again, you will see that a Clear softbutton item has been added to the menu.

Wallpaper

Wallpaper is the image displayed by the system when in idle. This may be no wallpaper, i.e. dark (as if unit has been turned o), the default setting, or your own personal wallpaper. If you choose to go for the latter, you should present your wallpaper to the unit by means of a memory stick connected to the USB socket of the unit. Your E20 will examine the memory stick contents and let you choose what to use. Selected contents will be copied to the E20. Just follow its instructions.

The le formats supported are *.jpg, *.png, *.gif.

Sounds and alerts

Ring tones allow you to select between the ring tones available. Use the

key to navigate up and down as usual. You will hear the dierent ring tones as you move up and down.

Get custom ring tones from USB. If the ring tones oered as standard are not

enough, you may add your own ring tones by means of a mem or y stick connected to the USB socket of the unit. Your E20 will examine the memory stick contents and let you choose what to use. Just follow its instructions. File formats supported are MPEG-4 AAC-LD and MPEG-4 AAC-LC, but not MP3.

www.cisco.com

Cisco IP Video Phone E20 Administrator guide

D14 330 .12 Adminis trator gui de Cisco IP Video Pho ne E20, TE4.1 Novembe r 2011.

Ring volume lets you set the volume of the incoming call signal. You will hear the

level as you adjust.

Key tones let you determine whether you should hear a sound every time you

press a key or not. Set to On to activate.

Flash screen on incoming calls. Set to On to activate.

Standby and screensaver

There is a standby function in the E20. When activated the standby function makes the screen go black after a time interval (delay) specied by you. This setting will override the screensaver feature.

You may add a screensaver of your choice to the E20. You will need a USB disk containing the photos (illustrations) you want to use as screensaver. If the USB stick contains multiple pictures, the contents will be shown as a gallery, one picture at a time.

A few things to observe:

• To continuously display the screensaver, the standby function must be

disabled.

• Once you have plugged in the USB disk, the E20 will produce a dialog asking you

whether the pictures on the USB disk should be displayed by the USB picture frame. The unit will read xcif data and even rotate images when necessary. The prompt will let you specify the time interval between the last time you operated (or used) the E20 and when the screensaver should start to appear.

• The USB disk must remain connected to the E20 to make this work.

• The following le formats are suppor ted: *.jpg, *.png, *.gif.

Language

Choose between English, Norwegian, Swedish, German, French, Korean, Italian, Dutch, Danish, Finnish, Portuguese, Japanese, Russian, Spanish, Spanish Latin, Turkish, Chinese Traditional, Chinese Simplied.

Camera control

Camera control lets you move your own camera up and down, in addition to set the exposure and whitebalance. Note that the camera will not move up and down physically, but the image will.

In a call, a softbutton for camera control will appear (the button in the middle). Pressing this will cause the unit to attempt to start moving the far end camera (Far End Camera

Controll—FECC). To move your own camera press the softbutton N ear end camera

(the leftmost button). Your own camera can be moved in vertical direction only.

Exposure and Whitebalance can be set manually or you can leave it up to the

E20 to set it for you.

Bluetooth™

You may connect a Bluetooth™ headset to the E20. To do that, you have to turn the Bluetooth support in the E20 to On and set your Bluetooth device in pairing mode.

Call fo rwar d Call forward lets you forward all calls to a dened receiver. Just key in the identity

and then activate the feature. When used with CUCM, the call forward information will also be known by the CUCM server. Changing this on the server or in the E20 will change the other setting accordingly. This implies that call forward will take place even if the E20 is unpowered, whenever it is used with CUCM. When not used with CUCM, the E20 must stay powered and connected for call forward to work.

Call settings Auto answer can be set to O or On. When set to O you must respond to an

incoming call to accept it, either by lifting the handset or by pressing the

key. When

set to On, the call is automatically accepted.

Default bitrate in calls can be set to 1152, 768, 512, 384, 256 or 128 kbps. Maximum upstream bitrate: 1152, 768, 512, 384, 256 or 128 kbps. Maximum downstream bitrate 1152, 768, 512, 384, 256 or 128 kbps.

The reason for allowing dierent upstream and downstream bitrate is to meet the need to specify dierent settings in asymmetric internet connections—typically when operating the E20 from home.

Date and time Date and time can be set to either Manual or Automatic.

If set to Automatic the menu allows you to update Time zone, Date format and

Time format only. When set to Manual you may change Day, Month, Year, Time upon 12/24 hrs, Date format and Time format.

HTTPS: Set to HTTPS to enable secure management. Requires HTTPS

to be enabled in the Network Services HTTPS Mode setting.

HTTPS test certicate: Set to On or O.

SNMP (Simple Network Management Protocol)

Used in network management systems to monitor network-attached devices (routers, servers, switches, projectors, etc) for conditions that warrant administrative attention. SNMP exposes management data in the form of variables on the managed systems, which describe the system conguration. These variables can then be queried (set to ReadOnly) and sometimes set (set to ReadWrite) by managing applications.

Mode: Set to O when you want to disable the SNMP network service. ReadOnly: Set to ReadOnly when you want to enable the SNMP

network service for queries only.

ReadWrite: Set to ReadWrite when you want to enable the SNMP

network service for both queries and commands.

Community name: Enter the name of the Network Services SNMP

Community. SNMP Community names are used to authenticate SNMP requests. SNMP requests must have a ‘password’ (case sensitive) in order to receive a response from the SNMP Agent in the codec. The default password is “public”. If you have the Cisco TelePresence Management Suite (TMS) you must make sure the same SNMP Community is congured there too. Note! The SNMP Community password is case sensitive.

System contact: Enter the name of the Network Services SNMP

System Contact.

System location: Enter the name of the Network Services SNMP

System Location.

Host IP 1–3: Enter the IP address of the SNMP Manager. All traps will

then be sent to the host listed. The system’s SNMP Agent responds to requests from SNMP Managers

(a PC program etc.). SNMP Traps are generated by the SNMP Agent to inform the SNMP Manager about important events. Can be used to send event created messages to the SNMP agent about dierent events like: system reboot, system dialing, system disconnecting, MCU call, packet loss etc. Traps can be sent to multiple SNMP Trap Hosts.

SIP

Determines whether the system should be able to place and receive SIP calls.

On: Set to On to enable the possibility to place and receive SIP calls.

This is the default setting.

O: Set to O to disable the possibility to place and receive SIP calls.

NTP (Network Time Protocol)

The Network Time Protocol (NTP) is used to synchronize the time of the system with a reference time ser ver. The time server will subsequently be queried every 24th hour for time updates. The time will be displayed on the top of the screen. The system will use the time to timestamp messages transmitted to Gatekeepers or Border Controllers requiring H.235 authentication. The system will use the time to timestamp messages transmitted to Gatekeepers or Border Controllers that requires H.235 authentication. It is also used for timestamping Placed Calls, Missed Calls and Received Calls.

Auto: The system will use the NTP server, by which address is supplied

from the DHCP ser ver in the network. If no DHCP server is used, or the DHCP server does not provide the system with a NTP server address, the system will use the static dened NTP server address specied by th e user.

www.cisco.com

Cisco IP Video Phone E20 Administrator guide

D14 330 .12 Adminis trator gui de Cisco IP Video Pho ne E20, TE4.1 Novembe r 2011.

Manual: The system will always use the static dened NTP server

address specied by the user.

SSH

Enables login via SSH.

Phonebook

Server 1

ID: Enter a name for the external phonebook. Addresses the specic

phonebook.

Typ e: Can be TMS (TANDBERG Management System) or VCS (Video

Communication Server)

URL: Enter the address (URL) to the external phonebook server.

Addresses the specic phonebook server.

Provisioning

Provides the possibility of managing the E20 by using an external manager/ management system.

External Manager

Address: Enter the name for the provisioning server. Protocol: http or https Path: Enter the path within the external manager to access the

provisioning information (if http-based provisioning.)

Domain: Enter the domain of the provisioning server

Mode

O: The system will not try to register to any management system. TMS: If set to TMS the system will try to register with a TMS server as

described in the address and path settings. TMS is short for TANDBERG Management System. Please contact your TANDBERG representative for more information.

VCS: If set to VCS the system will try to register with a VCS as described

in described in the address and path settings. VCS is short for Video Communication Server. Please contact your Cisco representative for more information.

HTTP: If set, the E20 will try to download conguration from a web

server. The URL is the concatenation of the External Manager address and the Path parameter. If the protocol is https, the E20 will use HTTPS during the download. If the HttpMethod parameter is POST, the E20 will do an HTTP post to the web server. Otherwise, it will do a HTTP Get to the web server. LoginName and password will be used if the web server requires username and password to download the conguration.

Callway: To use with Callway contact your Cisco representative for

more information.

CUCM: The E20 will try to connect to a Cisco Unied Communications

Manager. This requires that CUCM are version 8.5 or above and that the CUCM is aware of the E20.

Auto: If set, the E20 will enter auto provisioning mode and look for both

HTTP bootstrapping servers, VCS ser vers etc. This is the default mode.

the system. A Uniform Resource Identier (URI) is a compact string of characters used to identify or name a resource.

IncomingCallAlertLevel: Use this to select the level of alert when

someone calls. This feature may come in handy when the E20 is set up in shared lines enviroments. Select between Discreet, Regular and

Silent. The setting may be set separately for Idle and In-call situations. Default transport: Select the transport protocol to be used over the

LAN.

UDP: The system will always use UDP as the default transport

method.

TCP: The system will always use TCP as the default transport

method.

TLS: The system will always use TLS as the default transport

method. For TLS connections a SIP CA-list can be uploaded using the web interface. If no such CA-list is available on the system then anonymous Die Hellman will be used.

Auto: Uses TLS, if possible. If not, TCP will be tried and then UDP.

TLS verify: For TLS connections a CA-list can be uploaded from the

web interface.

On: Set to On to verify TLS connections. Only TLS connections to

servers, whom x.509 certicate is validated against the CA-list, will be allowed.

O: Set to O to allow TLS connections without verifying them. The

TLS connections are allowed to be set up without verifying the x.509 certicate received from the ser ver against the local CA-list. This should typically be selected if no SIP CA-list has been uploaded.

Typ e: Enables SIP extensions and special behaviour for a vendor or

pr o vid e r.

Standard: Should be used when registering to standard SIP proxy

like OpenSer.

Alcatel: Must be used when registering to a Alcatel-Lucent OmniPCX

Enterprise R7 or later.

Avaya: Must be used when registered to a Avaya Communication

Manager.

Cisco: Must be used when registering to a Cisco CallManager

version 5 or later.

Microsoft: Must be used when registering to a Microsoft LCS or

OCS server.

Nortel: Must be used when registering to a Nortel MCS 5100 or MCS

5200 PBX.

Broadsoft: Must be used when registering to a Broadsoft server.

NonStandard DTMF. Compatibility mode for non-standard DTMF

handling.

CallScreening: Proxy side call management. For Incoming and

outgoing call screening (RFC-5359). Default is O.

On: Enable call screening. The E20 will reply with “305 Use Proxy” for all

incoming SIP invites not from one of the proxies in the SIP Prole.

O: Turn o call screening.

Outbound: O SIP edge proxy to use for signalling. This can be used to

make the device accesible from outside a rewall.

Mailbox: SIP URI of media mailbox (i.e. voicemail, videomail).

MultiWay conference: Address of the MultiWay™ conference server.

To utilize the MultiWay server the address of the ser ver must be specied in Prole 1. There is no need for further specication (Prole 1 is enough to make it work).

Line: Select between Private and Shared. Private lines are regular

SIP-proles similar to the line concept in TE 2.0 and earlier versions. A shared line is a BroadWorks extension that is supported in TE 2.1 or higher. It means that several users (E20s with TE 2.1 and higher) can share a line. Whenever someone calls the shared line, all of the E20s that congured with the shared line will start ring. Whoever answers rst will take the call. However, it is possible for other users of the shared line to barge-in and join the call. Since Broadworks does not support video mixing in the current version, the joined call will be audio only. Once one of the users disconnects from the call, the video is resumed.

BusyLampField: Your Broadsoft BLF URI. When set up correctly this

will give you presence on your BLF enabled contacts. You can set speed dials to match your BLF contacts.

URI: Key in the URI of the E20 unit.

DisplayName: The name that you send to others when you call them.

Introduction

Cisco Discovery Protocol (CDP) is a proprietary layer-2 management protocol developed by Cisco in the early

1990s to provide enhanced automation of network discov-

ery and management. It is broadly deployed on millions of existing Cisco products and provides countless benets to network administrators for managing router and switch interfaces. With the introduction of IP Telephony in the late

1990s and early 2000s, CDP was enhanced to provide

additional automation capabilities for IP-based telephones, including automatic VLAN discovery, Power over Ethernet (POE) negotiation, Quality of Service (QoS) automation, location awareness (to automate the discovery of the physical location of an IP telephone for management

and emergency services purposes), Ethernet speed and duplex mismatch detection, and more.

Note: The IETF, IEEE and TIA, in cooperation with Cisco

and numerous other networking vendors, have since created the IEEE 802.1AB standard, known as Link-Layer Discovery Protocol (LLDP), with extensions developed for Media Endpoint Discovery (LLDP-MED) for voice and video endpoints. LLDP-MED will eventually subsume CDP, but this may take years to unfold due to the enormous installed-base and widespread use of CDP.

Cisco acquired TANDBERG in April 2010. The TANDBERG portfolio of video endpoints compliments Cisco’s existing

Telepresence and Unied Communications solutions. With

TANDBERG now a part of Cisco, one of the rst

steps towards integrating the portfolios is to add CDP support to the former TANDBERG products. CDP support is introduced on the Cisco E20 IP

Video Phone in release TE4.0. Similar support is

planned for the Cisco Telepresence EX series, Quick Set 20, C40/C60/C90 stand-alone integrator codecs, and the C-Series based Prole Systems, in release TC4.2.

However, because there is already an installedbase of these endpoint models (prior to the Cisco acquisition) that are not running CDP, introducing CDP in a software release requires careful consideration of how the new automation functionality will aect that existing installed-base. Enabling CDP by default could cause undesired behavior for those existing deployments when they upgrade to a CDP-enabled release and the devices suddenly begin using VLAN automation, so CDP is being introduced in a phased approach.

This document briey highlights the benets of

CDP, and the behavior of the Cisco E20 in release

TE4.0. A similar approach will be taken when in-

troducing CDP support in the TC4.2 software that runs on the EX and C-Series products.

Benets Provided by CDP

As mentioned in the introduction above, CDP provides numerous automation benets for network administrators deploying IP-based voice and video endpoints on their networks. This section briey highlights some of the most pertinent benets for IP-based voice/video endpoints like the Cisco E20.

Automatic VLAN discovery

Virtual L ANs (VLANs) allow a network administrator to introduce IP-based telephones and video terminals onto their network without the need for re-addressing their existing data subnets, or adding additional ethernet ports to their switches. Leveraging the 802.1Q standard, a device such as a Cisco E20 can tag its Ethernet frames with the VLAN ID that its trac belongs to, placing its trac into the voice / video VLAN (known as the auxiliary VL AN); while Ethernet frames sent by a PC are not tagged, and therefore end up in the data VLAN (known as the native VLAN). This allows the E20 to be inserted in between an existing PC and the Ethernet switch to which it is at tached, allowing for a single Ethernet port per user, thereby eliminating the need to add additional ports in the wiring closet, and allowing the E20 to be assigned to a dierent (new) IP subnet rather than consuming IP addresses in the existing PC VLAN. VLANs also allow the network administrator to apply dierent security and Quality of Service (QoS) policies on a per-VLAN basis.

Figures 1 and 2 illustrate these concepts. Without CDP (or LLDP-MED), the user must manually con-

gure each endpoint with the 802.1Q VLAN ID it should use. CDP automates this task, allowing the Ethernet switch to advertise to the endpoint the ID of the VLAN it should belong to.

Automatic Quality of Service

Quality of Service is essential for a well-performing network, providing preferential service to latency, jitter or loss sensitive applications like voice and video; deferential service to misbehaving applications such as viruses and other undesirable network trac; and fair treatment to routine, non-time sensitive trac such as email or web browsing. However, QoS can be complex to congure and manage, and the administrator needs to be assured that the trac entering the network is marked with the correct QoS values. For user-facing devices such as PCs, IP-based telephones and video terminals, the administrator must establish a demarcation point where QoS mark-

ings coming in from these devices are either not trusted— and instead overwritten to an administratively congured value—or trusted to set their own QoS values and the Ethernet switch will honor those values. This demarcation point, or trust boundary, ensures that if the user accidently, or intentionally, tampers with the QoS values assigned to these devices, those QoS values will be remarked by the administrator as they ingress the network.

CDP provides a method of automatically extending this trust boundary (at the administrators’ discretion) so that the phone or video terminal can mark its packets with the desired QoS values, and the switch will trust the phones packets (because the administrator knows that

the specic model of phone in question can be trusted to behave properly and cannot be tampered with) and forwards those packets on into the network. This functionality is known as AutoQoS on the Cisco Catalyst line of Ethernet switches. Figures 3 and 4 illustrate the concept of AutoQoS. More information on AutoQoS can be found at

http://www.cisco.com/en/US/docs/solutions/ Enterprise/WAN_and_MAN/QoS_SRND_40/ QoSCampus_40.html#wp1098057

Power over Ethernet (POE) negotiation

The 802.3af standard provides for Power over

Ethernet to devices such as IP-based telephones and video terminals. CDP provides additional benet by allowing the endpoint to indicate to the Ethernet switch how much power it requires—and for the switch to advertise to the endpoint how much power is available—thereby allowing more granular level of negotiation between the switch and the endpoint, and allowing the Ethernet switch to more closely track its available power budget. Note that POE is not used by the Cisco E20, but is mentioned here as informational benet to the reader since POE is widely used by many other models of Cisco Unied IP Phones,

Wireless Access Points, surveillance cameras, and myriad other devices.

Location Awareness

With the introduction of IP-based telephones, a new level of mobility was aorded in that an IP endpoints could be plugged in anywhere in the network, obtain an IP address, and start making calls, reducing the costs associated with physically patching telephone cables when moving an employee from one oce to another. However, certain management functions and emergency services rely on knowing the precise location of a telephone. CDP allows for network management applications to identify the physical location of a phone (by detecting what Ethernet port that phone is attached to, and hence, where it physically is located). This information is then leveraged by applications such as Cisco Emergency Responder to direct telephone calls made to emergency services personnel to the correct dispatch oce. There are many other real and potential uses for location information.

Ethernet Speed / Duplex Mismatch Detection

Ethernet devices use the 802.3 auto negotiation procedure to automatically negotiate their speed and duplex settings. However, a very common problem is that one side or the other is accidently congured for the wrong settings, resulting in packet loss. For example, the network administrator has congured all the Gigabit Ethernet por ts on the switch for auto negotiation, but the user accidently sets the port on his or her PC, IP phone or video terminal to a manually congured value, such as 100 Mbps / Full duplex. This can result in a mismatch between the switch and the endpoint, resulting in a large percentage of loss on that interface. CDP does not automate the resolution of such a condition, but it does detect it and cause an alarm to be generated on the switch, notifying the administrator of the condition so that he or she may take steps to resolve it.

Future Medianet Applications

The above benets of CDP have been available for years

from Cisco. Medianet is a new concept aimed at further extending and automating the interactions between endpoints and the network in order to deliver additional end-to-end optimization of multimedia trac across an intelligent internetwork. CDP is one protocol, among others, that will be leveraged by future generations of Cisco IOS Software and Cisco Medianet-ready endpoints to deliver on this vision. Available Medianet applications at the time this document was written include end-to-end tracing of the path a video session takes through a network in order to pinpoint the source of packet loss, optimizing the routing of video packets over alternate paths in order to maximize the throughput of the network, enhanced Session Admission Control in order to control the amount of video sessions admitted onto the network, and more.

CDP Behavior in Release TE4.0

When the Cisco E20 running release TE4.0 is booted for the rst time, or after a factory reset has been done, the following settings are applied by default:

xCongu ration Provisioning Mode: Auto

xCongu ration Network 1 VLAN Voice Mode: Off

xCongu ration Network 1 VLAN Data Mode: Off

The E20 then displays the Provisioning Wizard screen to

prompt the user for what provisioning mode they would like to use: VCS, Callway, CUCM, Broadsoft, HTTP, or Manual.

If CUCM is selected by the user, then xConguration

Provisioning Mode is automatically set to CUCM, xCon-

g u ration Net work 1 VLA N Voic e Mo d e and xCong u ration Net work 1 VLA N Dat a Mo d e are automati-

cally changed to Auto, and the phone begins utilizing CDP to automatically discover its VLAN and begins tagging its packets with the appropriate VLAN ID.

If the xConguration Provisioning Mode is set to TMS, VCS, Callw ay, Broadsoft or Manual, then

xCongu ration Network 1 VLAN Voice Mode and xCongu ration Network 1 VLAN Data Mode are left

in their default state of Off, and the phone will ignore any CDP VLAN advertisements and not tag its packets with any VLAN ID.

For TMS/VCS customers, this behavior preserves the functionalit y they had in previous software releases of the E20 so that the endpoint will continue to use untagged packets and remain on the VLAN it is currently using. If CDP is desired, then it may be manually enabled by setting the xConguration Network 1 VLAN Voice Mode and xConguration Network 1 VLAN Data Mode parameters to Auto.

For CUCM customers, this behavior does present an extra step in the rst-time bootup process, but once CUCM mode has been chosen in the Startup Wizard, CDP will automatically kick in and the phone will join the auxiliary (voice/video) VLAN. If the customer desires the E20 to not use CDP, then it may be manually disabled by setting the xConguration Network 1 VLAN Voice Mode and

xCongu ration Network 1 VLAN Data Mode param-

eters to Off.

For customers who do not have a CDP-capable Ethernet switch, but desire to use 802.1Q VLANs, the xCongura-

tion Network 1 VL A N Voic e Mo d e and xConguration Network 1 VL A N Dat a Mo d e parameters may be set to Manua l, and the associated xCon guration Netw ork 1 VL A N Voic e ID and xConguration Network 1 VL A N Dat a ID parameters may be set to their

appropriate values. Once these parameters are set, the settings are saved

and are persistent through subsequent reboots. If a user later wishes to change them, they may do so by rerunning the Startup Wizard, or by manually setting the parameters individually.

Upgrades to TE4.0 from a Previous Release

For existing customers upgrading to release TE4.0 from a previous release, the existing values for these parameters will be maintained, the Startup Wizard will not be displayed, and no change in behavior will be seen by the user. Note however that the values of the xCong ura-

tion Net wo rk 1 VL A N Voic e Mo de and xConguration Net wo rk 1 VL A N Data Mo de parameters have

changed. In previous releases, the valid values for these parameters were Untagged or Tagged, with Untagged behind the default. In release TE4.0, with the introduction of CDP support, the valid values for those parameters are now [Auto|Manual|Off]. During an upgrade, the previous values are automatically mapped to the new equivalent values.

Table 1 below illustrates the relationship between the old

and new values.

Prior Releases Release TE4.0.0 Comments

What Happens Next

Once a provisioning mode has been chosen by the user (or the xConguration Network 1 VLAN Voice

Mode and xConguration Network 1 VLAN Data Mode parameters have been manually congured), and

the E20 has decided which VLAN it belongs on, the following sequence of events occur:

1. The E20 will broadcast a DHCP DISCOVER on the

VLAN to which it assigned. The DHCP server is

expected to provide all the ordinary parameters—IP address, subnet mask, default router, domain name, DNS server(s), NTP server(s). In addition, it may provide one or more vendor-specic options to point the E20 to its provisioning ser ver:

a. Option 42, containing specic vendor-encapsulated-

options containing either of the following two methods: i. PROVISIONINGSERVER and

PROVISIONINGDOMAIN ii. TMSSERVER

b. Option 242, containing a 32-bit dotted-decimal

notation IP address of the Cisco Telepresence Management Suite (TMS).

c. Option 150, containing a 32-bit dotted-decimal

notation IP address of the Cisco Unied Communications Manager (UC Manager).

d. Option 66, containing a 32-bit dotted-decimal

notation IP address of a TFTP server.

2. The E20 then proceeds to obtain its conguration in

the following sequence.

a. Do a DNS lookup for tandbergprovisioning.<your_

domain_name>. If successful, attempt to use HT TP to fetch the conguration from that server.

b. If DHCP option 42 was received and contains the

PROVISIONINGSERVER and PROVISIONINGDOMAIN parameters, attempt to use VCS mode SIPbased provisioning.

c. If DHCP option 42 was received and contains the

TMSSERVER parameter, attempt to use TMS mode

HTTP-based provisioning.

d. If DHCP option 150 was received, containing the

IP address of the Unied Communications Manager provisioning server, attempt to contact that server using CUCM mode HTTP-based provisioning.

e. If DHCP option 66 was received, containing the IP

address of a TFTP server, attempt to contact that server using TFTP.

f. Do a DNS lookup for provisioning.tandberg.com. If

successful, attempt to use HTTP to fetch the conguration from that server.

Note: The DHCP process is actually done in the back-

ground prior to the Startup Wizard being displayed. This means that during the rst-time bootup, or after a factory reset has been done, the E20 will initially obtain a DHCP lease in the native VLAN. If CUCM mode is then chosen, and CDP indicates that a VLAN should be used, the E20 will release the address it received in the native VLAN, restart its IP stack, and re-DHCP a new address in the auxiliary VLAN. This may result in temporary usage of IP addresses in the native VLAN during the rst-time bootup.

A Note about DHCP Option 150

Some customers congure their DHCP server to process DHCP requests based on attributes contained within the request. For example, at Cisco, if a device requests DHCP Option 150 in its DHCP DISCOVER, the DHCP server will attempt to assign an address from a corresponding Auxiliary (Voice) VLAN. If the DHCP DISCOVER was sourced from a data VLAN, the DHCP server will fail to issue a DHCP OFFER for that device. This means that an E20 on Cisco’s internal network, if set to use VCS (and hence the xConguration Network 1 VLAN Voice

Mode and xConguration Network 1 VLAN Data Mode parameters are set to Off), the E20 will not be

issued an IP address, because the Cisco DHCP server will not OFFER an address to a device on the data VLAN which has requested DHCP Option 150 in its DISCOVER.

The workaround for Cisco internal users who are using

the E20 in VCS mode is to manually set the xCongura-

tion Net wo rk 1 VL A N Voic e Mo de and xCongurat io n Net wo rk 1 VLAN Dat a Mo de parameters to

Auto. Other customers may have similar DHCP rules in

place, so the user should consult their DHCP administrator to determine which VLAN they should set their E20 to use, and set the xConguration Network 1 VLAN Voice

Mode and xConguration Network 1 VLAN Data Mode parameters accordingly.

Summary

This document has briey introduced the history and

benets of the Cisco Discovery Protocol (CDP) and its behavior on the Cisco E20 IP Video Phone release TE4.0. CDP is a powerful mechanism for automating the application of VLANs and Quality of Service for voice/video devices, and existing TANDBERG customers are strongly encouraged to begin exploring its benets and preparing their networks so that they can begin leveraging VLANs, AutoQoS and VL AN-based security policies for the former-TANDBERG endpoints.
