4.3 Making and Answering Phone Calls

4.3.1 Handset, Speakerphone and Headset Mode

Handset can be switched between either Speaker or Headset. However, whenever the Headset is plugged in, Speaker will be switched to Headset.

To Switch between Handset and Speaker/Headset, simply press the Hook Flash in the Handset cradle or press the SPEAKER button in the phone.

4.3.2 Multiple SIP Accounts and Lines

GXV-3000 can support up to 3 independent SIP accounts. Each account is capable of independent SIP server, user and NAT settings among others. Each of the 3 LINE buttons (LINE1-LINE3) is “virtually” mapped to each SIP account. In off hook state, when user chooses an idle line, the name of the account (as configured in the web interface) will be displayed in the LCD while a dial tone is being played out. For example, if the 3 SIP accounts are named FWD (FreeWorldDialup), BroadVoice and Asterisk PBX respectively and they are all active and registered. When LINE1 is pressed, user will hear dial tone and see “FWD”. When LINE2 is pressed, user will hear dial tone and see “BroadVoice”. When LINE3 is pressed, user will hear dial tone and see “Asterisk PBX”.

For outgoing calls, GXV-3000 will pick up the LINE pressed, which the LED will be lit up in solid red color. User can switch the dialing account before dialing any digits by pressing the same LINE button one or more times. If user continues to press one LINE, the selected account will circulate among the registered accounts. For example, when LINE1 is pressed, LCD displays “FWD”. If LINE1 is pressed twice, LCD displays “BroadVoice” and the subsequent call will be made through SIP account 2.

- 15 -

GXV-3000 User Manual Grandstream Networks, Inc.

For incoming calls, if an account is configured and registered, all incoming calls for that account will attempt to use its corresponding LINE if it is not in use. When the “virtually” mapped line is in use, GXV-3000 will flash the next available LINE (from Left to Right) in red color.

A LINE is defined as “ACTIVE” when it is making or receiving a call, and its corresponding LINE LED is lit up in solid RED.

4.3.3 Making Calls

There are four ways to make phone calls:

1. Make Handset/SPEAKER/Headset off hook, or press the available LINE key to select a SIP

account, the corresponding LINE LED will light up in solid red. Enter the phone numbers and press the SEND key.

2. Make Handset/SPEAKER/Headset off hook, or press the available LINE key, the correspond-

ing LINE LED will light up in solid red. Press the SEND button to redial the last number called.

3. Press the OK to bring up the Main Menu, select Phone Book, browse phone book to the person

you want to dial, press OK to select and OK again when Dial is selected. The call will dial out in SPEAKER mode. (Right now this only applies to primary a/c which is LINE 1)

4. Paging/Intercom: This is ONLY valid if the SERVER/PBX support this feature and both

phone and PBX (for example, Asterisk) are configured correctly: Make Handset/SPEAKER/Headset off hook, select the LINE key to related feature available account, then press OK key again to see LCD showing: LINEx: PAGE USING. Now input the phone number you want to Page/Intercom and press SEND key.

NOTE:

• Once off hook and key pressed, the dialed number will be displayed on the LCD and the corre-

sponding DTMF tone will be played out.

• If the “SEND” button is not pressed after the phone number pressed, the phone (by default) will

wait for 4 seconds (no key entry timeout) before sending all digits out and initiating the call.

4.3.4 Making Calls using IP Address

Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy. VoIP calls can be made between two phones if

• Both phones have public IP addresses, or

• Both phones are on a same LAN/VPN using private or public IP addresses, or

• Both phones can be connected through a router using public or private IP addresses (with nec-

essary port forwarding or DMZ)

- 16 -

GXV-3000 User Manual Grandstream Networks, Inc.

To make a direct IP calling, press “OK” button to bring up MAIN MENU, the select “Direct IP Call” in the MENU and press OK to select, then key in the 12-digit target IP address, press OK key again to call out.

Examples: If the target IP address is 192.168.1.60 and port is 5062, like 192.168.1.60:5062, the key input to the Menu UI will be:

192*168*1*60#5062

followed by OK key to dial out, where “*” key represent “.” and “#” key represent “:”

• Quick IP Call Mode:

This model has the ability to dial an IP address under the same LAN/VPN segment by simply pressing the last octet in the IP address. This will allow user partially simulate a PBX functions using CMSA/CD without a SIP server. When doing this, controlled static IP usage is recommended.

In the “Advanced Settings” page there is an option "Use Quick IP-call mode", by default it is set to No. When this option is set to YES, and #XXX is dialed, where X is 0-9 and XXX <=255, phone will make direct IP call to aaa.bbb.ccc.XXX where aaa.bbb.ccc comes from the local IP address REGARDLESS of subnet mask.

#XX or #X are also valid so leading 0 is not required (but OK).

eg.

192.168.0.2 calling 192.168.0.3 just dial #3 follow by SEND or #

192.168.0.2 calling 192.168.0.23 just dial #23 follow by SEND or #

192.168.0.2 calling 192.168.0.123 just dial #123 follow by SEND or #

192.168.0.2 dial #3 and #03 and #003 has same effect --> call 192.168.0.3

NOTE:

• If you have a SIP Server configured, Direct IP-IP call will still work. However, if you are using

STUN, Direct IP-IP call will also use STUN.

• When doing Direct IP calling, make sure the “Use Random Port” is configured as “NO”. Otherwise

it will not work unless the phone is configured to listen to the special port you specified and also that port need to be inputted in the dialing digits.

4.3.5 Receiving Calls

There are three states when GXV-3000 receives a call:

1. When receiving an initial call. Besides ringing with selected Ring Tone, the corresponding ac-

count LINE will flash in red, taking Handset/SPEAKER/Headset off hook will enable user to hear the calling party in Handset/SPEAKER/Headset.

2. When receiving second or more incoming calls, besides playing stutter Call Waiting tone,

GXV-3000 will pick up the corresponding account LINE or the next available LINE as described in section 4.3.2.

3. When the related configuration is enabled for Paging/Intercom and the PBX (or Server) also

4. supports this feature, the phone will beep once and automatically establish the call via

SPEAKER.

4.3.6 Call Hold

While in conversation, pressing the “HOLD” button will put the other party on hold. User can resume the conversation by pressing the corresponding blinking LINE. User will also automatically put the current line on “HOLD” by pressing another available LINE for making or receiving other phone calls.

4.3.7 Call Waiting and Switch between Calls

GXV-3000 can switch to another line for making or answering calls and automatically put an ACTIVE call on Hold.

When receiving second or more incoming calls, besides playing a stutter Call Waiting tone, GXV-3000 will pick up the corresponding account or the next available LINE as described in section 4.3.2.

4.3.8 Call Transfer

GXV-3000 supports both BLIND and ATTENDED (or SUPERVISED) Transfer:

1. Blind Transfer: When a LINE is “ACTIVE”, user will get a dial tone by pressing the “TRNF”

button, then dial the number and press the “SEND” button, this will transfer the other party in the corresponding LINE to the dialed number.

2. Attended (or Supervised) Transfer: When in conversation with an “ACTIVE” LINE as defined

in section 4.3.2, user shall press “Linex” button to make a call and thus automatically puts the

- 18 -

GXV-3000 User Manual Grandstream Networks, Inc.

current ACTIVE LINE on HOLD. Once the call established, user just press “TRNF” key to transfer the call then hand up.

NOTE:

• Transferring calls across SIP domains needs to be supported by SIP service providers.

• Blind Transfer will usually use the Primary account SIP profile

4.3.9 3-Way Conferencing

GXV-3000 supports 3-way conferencing. With one LINE ACTIVE and another LINE on HOLD, press the CONF button then the LINE that is on HOLD (blinking), this will join the three parties together in a conference.

Once the conference established, press the CONF key will toggle between each other two sides of the videos.

If after pressing the “CONF” button, a user decides not to conference anyone, user can cancel it and resume the conversation by pressing CONF again or the original LINE button.

If the conference holder wishes to end a conference, simply press HOLD, which breaks the conference and places both parties on hold. The conference holder user can then talk to each individual party by selecting the corresponding blinking LINE.

4.3.10 Checking Message and Message Waiting Indication

When GXV-3000 is on-hook, pressing the MSG button will trigger the phone to call the VoiceMail Server (VMS) configured for the primary account. If a line/account is selected first, it dials the VMS configured for that account.

The MWI (Message Waiting Indicator) LED will flash in red color in three quarters of a second when voicemail server sends message waiting information to GXV-3000.

NOTE:

• This feature requires the phone to be configured correctly in the “VoiceMail User ID” field the

VM portal access number, also requires the Server to support this.

4.3.11 Mute / Delete

When in conversation with an ACTIVE LINE, pressing “MUTE/DEL” will mute the conversation, which means you can hear the other party but the other party cannot hear you. Pressing the button

- 19 -

GXV-3000 User Manual Grandstream Networks, Inc.

again will resume the conversation. When pressed, the red icon (muted microphone) will blink in the LCD to remind call is muted.

When dialing a number or during the Key Pad “MAIN MENU” configuration mode, press “MUTE/DEL” will delete the last entered digit.

When phone is idle, press the Mute/Delete key will function as a shortcut to Enable/Disable the DND (Do Not Disturb). When enabled, the red icon (Do Not Disturb) will blink in the LCD to remind user the DND is activated.

When there is an incoming call, press the Mute/Delete key while phone is ringing will REJECT the incoming call. The server will tell caller the user is busy and/or forward the call to Voice Mail if server support this feature and configured properly.

4.3.12 CAMERA BLOCK

User can press CAMERA BLOCK key to Disable/Enable the video sending out when in video call. If no video call wanted (privacy), user can press this button and make Audio Only call. When CAMERA BLOCK key is pressed, a red blocked camera will blink in the LCD to remind that the call is not in video mode and the camera is blocked.

There are two modes under which the GXV-3000 can operate:

• If DHCP mode is enabled, then all the field values for the Static IP

mode are not used (even though they are still saved in the Flash memory.) The GXV-3000 will acquire its IP address from the first DHCP server it discovers from the LAN it is connected. The DHCP option is reserved for NAT router mode (not implemented yet)

• To use the PPPoE feature the PPPoE account settings need to be set.

The GXV-3000 will attempt to establish a PPPoE session if any of the PPPoE fields is set.

• If Static IP mode is enabled, then the IP address, Subnet Mask, De-

Admin Password

Silence Suppression

Voice Frames per TX

Administrator password. Only administrator can configure the “Advanced Settings” page. Password field is purposely left blank for security reason after clicking update and saved. The maximum password length is 25 characters.

This controls the silence suppression/VAD feature of G723 and G729. If set to “Yes”, when a silence is detected, small quantity of VAD packets (instead of audio packets) will be sent during the period of no talking. If set to “No”, this feature is disabled.

This field contains the number of voice frames to be transmitted in a single Ethernet packet (be advised the max. size of Ethernet packet is 1500 byte (or 120k bit) so user should be aware that there IS a limit there). When setting this value, the user should be aware of the requested packet time (ptime, used in SDP message) as a result of configuring this parameter. This parameter is associated with the first codec in the above codec Preference List or the actual used payload type negotiated between the 2 conversation parties at run time. e.g., if the first codec is configured as G723 and the “Voice Frames per TX” is set to

e 2, then the “ptime” value in the SDP message of an INVITE request will be 60ms because each G723 voice frame contains 30ms of audio. Similarly, if this field is set to be 2 and if the first codec chosen is G729 or G711 or G726, then the “ptime” value in the SDP message of an INVITE request will be 20ms. If the configured voice frames per TX exceeds the maximum allowed value, the IP phone will use and save the maximum allowed value for the corresponding first codec choice. The maximum value for PCM is 10 (x10ms) frames; for G726, it is 20 (x10ms) frames; for G723, it is 32 (x30ms) frames; for G729/G728, 64 (x10ms) and 64 (x2.5ms) frames respectively. Please be very careful when massage those parameters. By adjust this, user also get jitter buffer changed accordingly. BT-100 phone has patent dynamic jitter buffer handling algorithm. The jitter buffer range from 20 ~ 200 ms. Incorrect setting will affect voice quality so do not touch the parameter if not understand and most of the case the default value will work in GS products. Please refer to the Codec FAQ in our website for more technical details:

http://www.grandstream.com/FAQ-Codec.pdf

Video Frame Rate

RTSP port

Layer 3 QoS

Layer 2 QoS

No Key Entry Timeout

Use # as Dial Key

Local RTP port

Use Random Port

Default is 554. The port for video surveillance camera data stream.

This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or Diff-Serv or MPLS. Default value is 48.

This contains the value used for layer 2 VLAN tag. Default setting is blank.

Default is 4 seconds.

This parameter allows users to configure the “#” key to be used as the “Send” (or “Dial”) key. If set to “Yes”, pressing this key will immediately trigger the sending of dialed string collected so far. In this case, this key is essentially equivalent to the “(Re)Dial” key. If set to “No”, this “#” key will then be included as part of the dial string to be sent out.

This parameter defines the local RTP-RTCP port pair the GXV-3000 will listen and transmit. It is the base RTP port for channel 0. When configured, channel 0 will use this port _value for RTP and the port_value+1 for its RTCP; channel 1 will use port_value+2 for RTP and port_value+3 for its RTCP. The default value is 5004.

This parameter, when set to Yes, will force random generation of both the local SIP and RTP ports. This is usually necessary when multiple GXV-3000s are behind the same NAT. Default is No.

Keep-alive interval

Use NAT IP

STUN Server

Firmware Upgrade

Via TFTP Server

This parameter specifies how often the GXV-3000 sends a blank UDP packet to the SIP server in order to keep the “hole” on the NAT open. Default is 20 seconds.

NAT IP address used in SIP/SDP message. Default is blank.

IP address or Domain name of the STUN server. STUN resolution result will display in the STATUS page of the Web UI.

This radio button will enable GXV-3000 to download firmware or configuration file through either HTTP or local TFTP server. This is mutual exclusive choice.

This is the IP address of the configured TFTP server. If selected and it is non-zero or not blank, the GXV-3000 will attempt to retrieve new configuration file or new code image from the specified TFTP server at boot time. It will make up to 3 attempts before timeout and then it will start the boot process using the existing code image in the Flash memory. If a TFTP server is configured and a new code image is retrieved, the new downloaded image will be verified and then saved into the Flash memory.

Note: It is strongly recommended that user upgrade firmware locally in LAN environment if using TFTP to upgrade. Please do NOT interrupt the TFTP upgrade process (especially the power supply) as this will damage the device.

Syslog Server

The URL for the HTTP server used for firmware upgrade and configuration via HTTP. For example,

http://provisioning.mycompany.com:6688/Grandstream/1.0.0.33

Here “:6688” is the specific TCP port that the HTTP server is listening at, it can be omitted if using default port 80.

Note: If Auto Upgrade is set to No, GXV-3000 will only do HTTP download once at boot up.

Default is No. Choose Yes to enable automatic HTTP upgrade and provisioning. In “Check for upgrade every” field, enter the number of minutes to enable the phone to check the HTTP server for firmware upgrade or configuration changes in the defined period of time. When set to No, the phone will only do HTTP upgrade and configuration check once at boot up. Used by ITSP. End user should NOT touch these parameters.

This parameter sets the payload type for DTMF using RFC2833. Default is 101.

GXV-3000 User Manual Grandstream Networks, Inc.

Use Quick IP Call Mode

This model has the ability to dial an IP address under the same LAN/VPN segment by simply pressing the last octet in the IP address, without SIP server required.

In the Advanced Settings page there is an option "Use Quick IP-call mode", by default it is set to No. When this option is set to YES, and #XXX is dialed, where X is 0-9 and XXX <=255, phone will make direct IP call to aaa.bbb.ccc.XXX where aaa.bbb.ccc comes from the local IP address REGARDLESS of subnet mask.

#XX or #X are also valid so leading 0 is not required (but OK).

eg.

192.168.0.2 calling 192.168.0.3 just dial #3 follow by SEND or #

192.168.0.2 calling 192.168.0.23 just dial #23 follow by SEND or #

192.168.0.2 calling 192.168.0.123 just dial #123 follow by SEND or #

192.168.0.2 dial #3 and #03 and #003 has same effect --> call 192.168.0.3

Note:- If you have a SIP Server configured, Direct IP-IP call will still work. However, if you are using STUN, Direct IP-IP call will also use STUN.

Default is set to No.

Lock keypad update

If this parameter is set to “Yes”, the configuration changes via keypad are disabled therefore the phone is some kind of locked.

NAT Traversal

Subscribe for MWI:

Proxy-Require

Voice Mail User ID

Send DTMF

This parameter defines whether the GXV-3000 NAT traversal mechanism will be activated or not. If activated (by choosing “Yes”) and a STUN server is also specified, then the GXV-3000 will behave according to the STUN client specification. Under this mode, the embedded STUN client inside the GXV-3000 will attempt to detect if and what type of firewall/NAT it is sitting behind through communication with the specified STUN server. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the GXV-3000 will attempt to use its mapped public IP address and port in all of its SIP and SDP messages. If the NAT Traversal field is set to “Yes” with no specified STUN server, the GXV-3000 will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.

Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication will be sent periodically.

SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

When configured, user will be able to dial voice mail server by pressing “MSG” button. This ID is usually the VM portal access number.

This parameter specifies the mechanism to transmit DTMF digit. There are 3 modes supported: in audio which means DTMF is combined in audio signal (not very reliable with low-bit-rate codec), via RTP (RFC2833), or via SIP INFO.

Account Ring Tone

Send Anonymous

Auto Answer

Preferred Vocoder

There are 4 different ring tone that are defined:

• System Ring Tone: when selected, all calls will ring with system ring

tone.

• Customer Ring Tone 1 to 3: when selected, GXV-3000 will ONLY

play this ring tone for all the incoming calls for this account.

If this parameter is set to “Yes”, the “From” header in outgoing INVITE message will be set to anonymous, essentially blocking the Caller ID from displaying.

When set to “Yes”, GXV-3000 will automatically switch on speaker to answer the incoming call. Set to Intercom/Paging mode, it will answer the call based on the SIP info header from the server. Default is No.

5.3 Configuration through Central Provisioning Server

Grandstream GXV-3000 can be automatically configured from a central provisioning system.

When GXV-3000 boots up, it will send TFTP or HTTP request to download configuration file which is “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the GXV-3000.

The configuration file can be downloaded via TFTP or HTTP from the central server. A service provider or an enterprise with large deployment of GXV-3000 can easily manage the configuration and service provisioned for individual device from a central server remotely.

Grandstream provides a licensed provisioning system called GAPS that can be used to support automated configuration of GXV-3000. GAPS (Grandstream Automated Provisioning System) uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual GXV-3000 for firmware upgrade, remote reboot, etc.

Grandstream provide GAPS (Grandstream Automated Provisioning System) service to VoIP service providers. It could be either simple redirection or with certain special provisioning settings. Initially upon booting up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices with redirection settings so that they will be redirected to customer’s TFTP or HTTP server for further provisioning. Grandstream also provides GAPSLite software package which contains our NAT friendly TFTP server and a configuration tool to facilitate the task of generating device configuration files.

The GAPSLite configuration tool is now free to end users. The tool and configuration templates can be downloaded from http://www.grandstream.com/DOWNLOAD/Configuration_Tool/.

For details on how GAPS works, please refer to the documentation of GAPS product or contact Grandstream Sales Department for more information.

6 Software Upgrade & Customization

Software (or firmware) upgrade can be done via either TFTP or HTTP. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page.

6.1 Firmware Upgrade through TFTP/HTTP

To upgrade via TFTP or HTTP, user needs to select TFTP or HTTP upgrade method. “Upgrade Server” needs to be set to a valid URL of a HTTP server. Server name can be in either FQDN or IP address format. Here are examples of some valid URL.

e.g. firmware.mycompany.com:6688/Grandstream/1.0.0.18

e.g. 168.75.215.189

There are two ways to set up the Upgrade Server to upgrade firmware, namely through the Key Pad Menu or via the GXV-3000’s Web configuration interface. To configure the Upgrade Server via Key Pad Menu options, select “System Config” from the Main Menu, then select “Upgrade Preferences”. Under this sub Menu, user can edit Upgrade Server in either an IP address format or FQDN format. Choose “Save and use TFTP” or “Save and use HTTP” to select upgrade method. And select “Reboot” from the Main Menu to reboot the phone.

To configure the Upgrade Server via the Web configuration interface, open up your web browser and enter the IP address of GXV-3000. Enter the admin password to get into the web configuration interface. In the ADVANCD SETTINGS page, enter the Upgrade Server’s IP address or FQDN in the “Upgrade Server” field. Select TFTP or HTTP upgrade method. Once these settings are entered, user needs to update the change by clicking the “Update” button. Then “Reboot” or power cycle the phone, the firmware files will be fetched upon booting up.

If the configured upgrade server is found and a new code image is available, the GXV-3000 phone will attempt to retrieve the new image files by downloading them into the phone’s SRAM. During this stage, the GXV-3000 phone’s LCD will show firmware file downloading process. Upon verification of checksum, the new code image will be saved into the Flash. If firmware upgrade fails for any reason (e.g., TFTP/HTTP server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the GXV-3000 phone will stop the upgrading process and simply boot using the existing code image in the flash.

Firmware upgrading may take as long as 45 minutes over Internet, or just 5 minutes on a controlled LAN. It is strongly recommended to conduct firmware upgrade in a controlled LAN environment whenever possible.

For users who do not have local TFTP server, Grandstream provides a NAT-friendly TFTP server on the public Internet for users to download the latest firmware upgrade automatically. Please check the Services section of Grandstream’s Web site to obtain this TFTP server IP address:

- 44 -

GXV-3000 User Manual Grandstream Networks, Inc.

Alternatively, user can download and install a free TFTP or HTTP server in his/her LAN to do firmware upgrading.

A free Windows version TFTP server can be downloaded from:

http://support.solarwinds.net/updates/New-customerFree.cfm.

Our latest official release can be downloaded from: http://www.grandstream.com/y-firmware.htm Unzip the file and put all of them under the root directory of the TFTP server. Put the PC running the TFTP server and the GXV-3000 phone in the same LAN segment. Please go to File -> Configure -> Security to change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the firmware upgrade. Start the TFTP server, in the phone’s web configuration page, configure the Firmware Server Path with the IP address of the PC, update the change and reboot the unit.

User can also choose to download the free HTTP server from http://httpd.apache.org/ or just use Mi-

crosoft IIS web server

NOTE:

• When GXV-3000 phone boots up, it will send TFTP or HTTP request to download configura-

tion file “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the GXV-3000

phone. This file is for initial automatically provisioning purpose only, for normal TFTP or

HTTP firmware upgrade, the following error messages in a TFTP or HTTP server log can be

ignored.

TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does not exist

Configuration File Download

NOTE:

• After flashing the firmware, a power cycle is required. Please power cycle the phone after

the downloading process finished and when the LCD becomes pale or white. For new

hardware version 1.1 or later, the phone will automatically reboot after the new firmware

get flashed.

GXV-3000 User Manual Grandstream Networks, Inc.

6.2 Configuration File Download

Grandstream SIP Device can be configured via Web Interface as well as via Configuration File through TFTP or HTTP. “Upgrade Server” is the TFTP or HTTP server path for configuration file. It needs to be set to a valid URL, either in FQDN or IP address format.

A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding configuration template of the firmware.

When Grandstream Device boots up or reboots, it will issue request for configuration file named “cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. The configuration file name should be in lower cases.

6.3 Managing Firmware and Configuration File Download

When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in minutes, default and minimum is 60 minutes) to have the devices periodically check with either Upgrade Server. This allows the device periodically check if there are any new changes need to be taken on a scheduled time. By defining different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware or Provisioning Server load at any given time.

6.4 Customization own Screensaver Images

User can customize the screensaver images by using the free “screensaver picture generator tool” downloadable from our website: http://www.grandstream.com/y-downloads.htm

User can put own preferred JPEG images into the phone as screensaver. Here are the requirements of the pictures which can be converted as screensaver:

• Baseline JPEG

• 320x240 in dimension

• RGB color space

• 8-bit data

- 46 -

GXV-3000 User Manual Grandstream Networks, Inc.

There is a limitation for the flash size to hold the screensaver image file (image.bin) also. Currently the screensaver file (image.bin) limitation is 20 images or 320kb whichever limit is reached first. Screensaver picture can be changed the same way as customized ring tone.

Users are recommended to resize the picture using popular photo processing software. Following screen shots are captured from Adobe Photoshop to resize image to prepare the screensaver images.

• Picture MUST be preprocessed and resized to 320 x 240

• Picture must be saved in Baseline JPEG format.

- 47 -

GXV-3000 User Manual Grandstream Networks, Inc.

Here is the screen shot of the Screensaver Tool Utility:

Please keep in mind the limitation of the image.bin file. Once the file is generated by this utility tool, please put the file into the same folders containing firmware files.

The screensaver image flashing follows the same way of firmware flashing, either TFTP or HTTP. But if the firmware is already the latest one, user can just put the only one file “image.bin” there to allow the phone to get it.

Be advised do NOT interrupt the power supply when doing ANY file flashing as that will risk damage the phone. Users with high frequent power outage are recommended to have UPS hooked on before doing any firmware or screensaver or ring tone flashing.

- 48 -

GXV-3000 User Manual Grandstream Networks, Inc.

6.5 Customization own Ring Tones

User can customize the ring tone using the free tool downloadable from our website: http://www.grandstream.com/y-ringtone.htm

Please follow the same rules as the Screensaver to generate the ring tone files and load them into the phone.

Here are the requirements of the files which can be converted as ring tones:

• Must be either .wav or .mp3 format, recommended .wav format

• Converted file size must be less than 64KB

Here is the screen shot of the ring tone generating tools:

Since the phone only can hold 3 ring tones files in total with each less than 64KB in file size. If user loading a ring tone file bigger than 64KB in size, it will occupy next available ring tone file slot and the total ring tones WILL be reduced accordingly. If the big file is “ring3.bin”, the ring tone will get dropped and can not be loaded into the phone.

User can not change the file name generated to other names except the ring1.bin, ring2.bin and ring3.bin.

8 Video Surveillance

GXV-3000 can be turned into a video surveillance camera. It works very well if the monitor device and the GXV-3000 are in the same LAN. If the monitor device is out side the router in another LAN through two routers, unless tweaks the routers correctly, it is very hard to make that working correctly and reliably. This is mostly caused by the routers involved.

We suggest this kind of application in LAN environment or both sides have public IP.

Here are procedures of how to configure this feature working:

¾ Phone side:

In the ADVANCED SETTING page, find the following field and change from default setting NO to YES, reboot the device.

¾ PC side (Monitor Device):

1. Download VLC from http://www.videolan.org/vlc/. This is the only player so far that works

and support RFC 3984.

2. Launch VLC.

3. Go to Preferences->Input/Codecs->Demuxers->H264, check “Advanced options” in the bot-

tom. The option “Frames per Second” will show. Change that value to 5 and then save.

4. Go to Preferences->Input/Codecs->Access modules->Real RTSP, check “Advanced options” in

the bottom. The option “Caching value (ms) will show. Change that value to 1000 and then

save. You may change it to a smaller value to reduce the delay.

5. If the viewer is under NAT, go to Preferences->Demuxers->Access modules->RTP/RTSP,

check “Advanced options” in the bottom. The option “Use RTP over RTSP (TCP)” will show.

Check that option box. (We do NOT recommend this network environment as the router will

cause unreliable issues)

6. Close the Preferences window and go to File->Open Network Stream: a) Select RTSP as the protocol b) Enter the URL in the format of

rtsp://admin:ADMIN_PASSWORD@DEVICE_IP_ADDRESS:DEVICE_RTSP_PORT.

You need to change the text in red according to your configuration: ADMIN_PASSWORD is the device’s web configuration password for admin. DEVICE_IP_ADDRESS is the device IP. DEVICE_RTSP_PORT is the RTSP port setting of the device. If the port uses default value 554, the port portion can be omitted from the URL

c) Click OK and you should see the video starts

- 54 -

GXV-3000 User Manual Grandstream Networks, Inc.

There are several limitations:

1. Currently it supports only 2 concurrent views on GXV. The video stream is set at 5 frame per sec-

ond and 128kbps.

2. The video stream will stop if a call starts. The phone’s video stream server will not actively termi-

nate the session, but most clients will tear down the session after certain interval without video stream.

Following is a sample screen shot of the PC client side running VLC as monitoring station:

ECHO CANCELLATION

H.323

H.264

Echo Cancellation is used in telephony to describe the process of removing echo from a voice communication in order to improve voice quality on a telephone call. In addition to improving quality, this process improves bandwidth savings achieved through silence suppression by preventing echo from traveling across a network.

There are two types of echo of relevance in telephony: acoustic echo and hybrid echo. Speech

compression techniques and digital processing delay often contribute to echo generation in telephone networks.

A suite of standards for multimedia conferences on traditional packet-switched networks.

H.264, MPEG-4 Part 10, or AVC, for Advanced Video Coding, is a digital video standard which is noted for achieving very high data compression

. It was written by the ITU-T

codec

Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts

Group (MPEG) as the product of a collective partnership effort known as the Joint Video Team

(JVT). The ITU-T H.264 standard and the ISO/IEC MPEG-4

Part 10 standard (formally, ISO/IEC 14496-10) are technically identical. The final drafting work on the first version of the standard was completed in May of 2003.

- 59 -

GXV-3000 User Manual Grandstream Networks, Inc.

The intent of H.264/AVC has been to create a standard that would be capable of providing good video quality at bit rates that are substantially lower (e.g., half or less) than what previous standards would need (e.g., relative to MPEG-2, H.263, or MPEG-4 Part 2).

HTTP

Hyper Text Transfer Protocol; the World Wide Web protocol that performs the request and retrieve functions of a server

Internet Protocol. A packet-based protocol for delivering data across networks.

IP-PBX

IP-based Private Branch Exchange

IP Telephony

(Internet Protocol telephony, also known as Voice over IP Telephony) A general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). The basic steps involved in originating an IP Telephony call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet or other packet-switched networks; the process is reversed at the receiving end. The terms IP Telephony and Internet Telephony are often used to mean the same; however, they are not 100 per cent interchangeable, since Internet is only a subcase of packetswitched networks. For users who have free or fixed-price Internet access, IP Telephony software essentially provides free telephone calls anywhere in the world. However, the challenge of IP Telephony is maintaining the quality of service expected by subscribers. Session border controllers resolve this issue by providing quality assurance comparable to legacy telephone systems.

IVR

IVR is a software application that accepts a combination of voice telephone input and touchtone keypad selection and provides appropriate responses in the form of voice, fax, callback, email and perhaps other media.

OBP/SBC

Outbound Proxy or another name Session Border Controller. A device used in VoIP networks. OBP/SBCs are put into the signaling and media path between calling and called party. The OBP/SBC acts as if it was the called VoIP phone and places a second call to the called party. The effect of this behavior is that not only the signaling traffic, but also the media traffic (voice, video etc) crosses the OBP/SBC. Without an OBP/SBC, the media traffic travels directly between the VoIP phones. Private OBP/SBCs are used along with firewalls to enable VoIP calls to and from a protected enterprise network. Public VoIP service providers use OBP/SBCs to allow the use of VoIP protocols from private networks with internet connections using NAT

Simple Traversal of UDP over NATs, is a network protocol allowing clients behind NAT (or multiple NATs) to find out its public address, the type of NAT it is behind and the internet side port associated by the NAT with a particular local port. This information is used to set up UDP communication between two hosts that are both behind NAT routers. The protocol is defined in

RFC 3489. STUN will usually work well with non-symmetric NAT routers.

TCP

Transmission Control Protocol, is one of the core protocols of the Internet protocol suite. Using

TCP, applications on networked hosts can create connections to one another, over which they

can exchange data or packets. The protocol guarantees reliable and in-order delivery of sender to receiver data.

TFTP

Trivial File Transfer Protocol, is a very simple file transfer protocol, with the functionality of a very basic form of FTP; It uses UDP (port 69) as its transport protocol.

UDP

User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using

UDP, programs on networked computers can send short messages known as datagrams to one
