The VG248 can receive message-waiting indicator (MWI) information from Cisco CallM an ag er an d s en d it to an al og p h on es. The VG2 4 8 sen ds MWI messages using any of the following methods:

• Playing stutter dial tone when a user picks up the phone

• Illumi nating th e MW I lamp on th e ph o ne

• Using caller ID m e ch anism to se n d in f orm ation to t he L C D sc re e n on the

phone

Yo u can enabl e or disable any of these opti ons. See th e “Choosing Message

Waiting Indicator Type” section on page 3-11 for deta ils .

Understanding Call Control Modes

Chapter 1 Overview

The VG248 supports different call control modes, which indicate how users access an d use t he s up por ted tele ph o ny feat ur es. You can cho os e th e call con tr o l mode appropriate to the specific needs of your users and the abilities of your analog devices. The supported call control modes include:

• Basic

• Standard

• Feature

T o und erst and t he dif fe re nce s amon g th e thre e mo des, k e ep in mind t he fol l o wing tips:

• The three modes differ in how they support transfer and conference.

• All modes support call waiting, and you can disable it on a per port basis

using Cisco CallManager.

• All mo de s su pp o rt feat ur e co de s f or s p eed d ia l, re di al, call for wa rd an d

pickup, and you can define or disable them on a per device basis.

• Users can access features using the hook flash, 0-9, *, or # buttons, depending

on how you have configured the feature codes.

• You cannot use a double flash hook.

Standard is the default telephony mode, and it provides standard Bellcore features, s uc h as u sed i n N o r th A m eri ca.

Users use the flash button or hook flash to transfer, conference and hold calls, with t he f ollowin g re qu ir ements :

• You cannot use a double hook flash to end a call.

Feature

• When putting calls on hold, the first call can be e ither incoming or outgoing.

• When tran sferring a c all or establishing c o nferences, the second call must be

outgoing.

Users al so us e f eat ure code s to ac tivate ot he r features i n stan d ar d mod e. See

Table 1-1 for details about how the telephony features are accessed in standard

mode.

For simple call s , th e fe atu r e mode i s indist in guishabl e f r om th e s t an da rd m od e. While on calls, users use the flash button or hook flash to get a second dial tone to dial a secon d pa rt y. However, users then mu s t en ter feature co d e s t o t r an sfe r the call o r establish a confer en ce .

When usi ng feat ure m o de wi th tw o ca lls es tabl is hed, t he ho ok flas h cyc les ar oun d four states:

Understanding How the VG248 Supports Telephony Features

These di fferen t s tat es enable y ou to keep both calls active and s w it ch b etw e en them. Thus, unlike Standard mode you can keep both calls active for as long as you want and freely switch between them.

T o transfer or conference, you need to enter the relevant feature code at one of the feature t o nes (w h ic h ar e si m il ar to d ial tones exce pt y ou can only enter f eat ur e codes r ath er t ha n be in g ab le to d ial a d i re cto ry numb er).

Understanding Caller ID Support

If you have activated caller ID on Cisco CallManager, the VG248 can collect that informat io n and pa ss it on to an alog ph on es. You can d isable ca ll er I D on a per port basis. This enables you to support caller ID on some analog phones and not on others (see the “Enabling Caller ID” section on page 3-11 for details).

The VG248 supports the following caller ID standards:

• Bellco re G R- 3 0- CORE—North Am er ica

• ETS 300 648 and ETS 300 659-1—Europe (excluding the United Kingdom)

• British Telecom SIN227 and SIN 242—United Kingdom

Supported Analog Devices

When a call ar r ives, th e VG 2 48 s en d s th e fo ll owing i nf o rm ati on :

• Time and date in form atio n

• Calling number up to 18 digits when available, otherwise the reason why

• Callin g n ame up to 2 0 ch ar act er s w h en availab le

Supported Analog Devices

The VG248 has a maximum ringer equivalency number (REN) load of three (3) analog devices per line (using a shared directory number), and only two of these devices can be off-hook at any one time.

You should use analog devices designed to work in the country in which you are using the VG248. For example, if you are using the VG248 in the United Kingdom, you should use analog devices designed for use in that country.

Chapter 1 Overview

Speakerphones

The VG248 pe rforms line ec ho cancel lat ion, bu t it does not perfor m acoust ic echo cancell ati on . S p ea ker p hones wi th bui lt -in ech o cance ll ati on su ch as the Polycom-brand phones should work fine. However the voice quality might be unsatisfactory when using a speakerphone that does not perform acoustic echo cancell ati on i tself.

Private Line Automatic Ringdown Phones

A telephon e conf igur ed as a Pri va te Line Auto matic Rin gdo wn (PLAR) telepho ne dials a pre-configured number when it goes off-hook. You cannot use PLAR phones to dial any other numbers. Telephones in hotel lobbies and airports are often configured in this way.

Supported Analog Devices

Fax Machines

Modems

Cisco CallManager release 3.0 and later can be configured to support the PLAR phone fe atu re for a n IP pho ne or for an a nalo g tel ep hone c onnec ted to t he VG2 48.

The V G248 supp orts fax m achines in pass-through and Cisco fax relay modes. In fax pass-through mode, the gateways do not distinguish a fax call from a voice call. Cisco fax relay offers a more reliable way of transporting the fax data in order to increase the data rate. However, the terminating gateway must also support Cisco fax relay. If necessary, you can disable Cisco fax relay (see the

“Disabling Cisco Fax Relay” section on page 3-3 for details) .

The VG248 supports modems in pass-through mode.

Supported Protocols

The VG248 supports several industry-standard and Cisco networking protocols required for voice communication over an IP network. Additionally, the VG248 supports protocols required for remote network management.

These sections provide an overview of the protocols supported by the VG248:

• Data and Voice Protocols, page 1-10

• Network Management Protocols, page 1-10

Data and Voice Protocols

The VG248 supports the following data and voice communication protocols.

Chapter 1 Overview

• Internet Protocol (IP)—addresses and sends packets across the network.

• Inte r net Gr ou p Manage m e nt Pr ot ocol ( IG M P ) — u s ed to report multicast

group memberships

• Trivial File Transfer Protocol (TFTP)—allows you to transfer files over the

network.

• Hyper Text Trans f e r P r ot ocol ( H T TP ) — d e fi nes how m essages a re for matte d

and trans mitte d, and what acti ons Web servers and browsers s hould take in respons e to va ri ous c omma n ds .

• File Transfer Protocol (FTP)—allows you to transfer files over the network.

• Dynam ic Hos t Con figurat ion P roto col (DH CP )—d ynam ica lly allo ca tes and

assi gn s an IP a ddres s to networ k devic es .

• Real-Time Transport Protocol (RTP)—enables transporting of real-time data,

such as inter a ctive voic e a n d v ideo over data networ ks.

• Skinny Client Control Protocol (SCCP)—enables communication between

the VG24 8 an d Ci sc o CallM an ag er.

Network Management Protocols

The VG248 supports Simple Network Management Protocol (SNMP) and implements several industry-standard Management Information Bases (MIBs).

Cisco VG248 Analog Phone Gateway Software Configuration Guide

1-10

OL-1209-02

Chapter 1 Overview

Understanding SNMP Support

The VG248 supports SNMP versions 1 and 2, enabling you to perform the following commands:

• Get—Retrieve a specific node’s value.

• GetNext—Retrieve the first value present in the ordered tree whose node

succee ds th e o n e s p ec ifie d.

• GetBulk—Retrieve bounded number of values whose nodes succeed, in the

numer ica l orde rin g, the on e spe cified. GetBulk is a vailabl e only in SNMP v2.

• Set—S et a s pe cifi c valu e.

Understanding Trap Support

The VG248 generates the following general traps, as defined in RFC 1157:

Supported Protocols

• Cold st ar t—whe n the VG24 8 star ts up a nd o bt ai ns an IP ad dr ess

• Warm start—when the VG248 changes IP addresses

• Authe nt ic ation fa il ur e— w hen an invalid commu n ity string i s u s ed

Yo u mu st h ave se t at lea s t on e networ k m anage ment s tation in or der f or the VG248 to generate traps. See the “Configuring Trap Settings” section on

page 2-1 4 for details.

Understanding Supported MIBs

The VG248 supports the following MIBs.

RFC 1213

RFC 1213 is the basi c MIB 2 specif i cat io n whic h indi cat es th e sta te of embe dd ed interfaces and s tat ist ics fo r n etw o rk p r ot oc ol s .

The VG248 supports RFC 1213 with the following caveats:

• ifAdm in Stat u s f or t he Ethernet inte rface cann ot b e w ritten, an d i t i s fixe d at

“up”.

• ifSpeci ficfo r a ll in terface s r etu r ns as “ 0, 0” .

• atTable c an no t be w r itt en .

OL-1209-02

Cisco VG248 Analog Phone Gateway Software Configuration Guide

1-11

Supported Protocols

Chapter 1 Overview

• No “ip***” values can be written.

• You cannot write to “tcpConnState” for an active TCP connection.

• The VG248 does not implement the External Gateway Protocol (EGP).

Interface MIB

This MIB is defin ed in RFC 1573 and e xtends the range of information availabl e about a device's interfaces from that provided by the ifTable in RFC 1213. The VG248 implements this MIB for its Ethernet interface and the 48 FXS interfaces. However, the octet or packet count values are not available for the FXS interfaces becaus e th ey a re not applic ab le to these inte rface typ es .

RMON

The VG248 implements the Ethernet Statistics group in Remote Monitoring (RMON ), w it h th e ex cep ti on o f “Et he r St at sS tat us. ” This is fixed at “val id ” a nd cannot be written.

Cisco CDP MIB

Cisco D is covery P ro t o co l (CD P ) is a m e thod t hat Cis co devices us e to advert is e their presence and to discover information about other nearby devices. The VG248 supports CDP and implements this MIB. You can enable or disable CDP on the VG2 48 . S ee t h e “Ena bl in g CDP” section on pag e 2-10 for de tails .

Cisco Process MIB

This MIB describes the processes currently running on the device. However, because the VG2 4 8 ru n s th r ead s, r ather than p rocesses, t he M I B i s impleme nt ed with t he f ol low in g caveats:

• The amount of memory allocated is not recorded on a per-thread basis.

Therefore, cp m Pr oc Ex tM em Al lo ca ted a nd cp m Pr o cEx tMemFreed ar e returned as 0.

• All threads run at the same priority. Therefore, every process

cpmProcExtPriority are returned as “normal.”

• It is not possi bl e t o cha ng e a proces s’s prior it y, so attempts to w r it e

“cpmPro cEx tPr io r it y” ar e un s uc cessf u l.

Integrating Cisco CallManager with Voice Mail Systems Using SMDI

Simplified Message Desk Interface (SMDI) defines how phone system s provide voice mail systems with the information needed to intelligently process incoming calls. It is an industry-s tandard signaling protocol that supplies calling and called party identification and sets and clears Message Waiting Indicators (MWIs) through an RS-232 serial connection.

Using SMDI and the VG248, you can integrate your existing voice mail systems (such as Lyrix, Octel 200, Octel 250, Octel 300 and Octel 350) and legacy PBX systems with Cisco CallManager.

Each VG248 system enables you to use up to 48 ports for voice mail access. If you need more than 48 port s, you can use the chained co nfigur ation. The chained configurati on ( see Figure 5-2) enables you to connect multiple VG248 devices together, expanding the number of voice ports available for your voice mail integration.The SMDI information is shared and passed between the VG248 devices via the As y nc por ts .

Configuration Tips

When using multiple VG248 syste m s, refer to these tips. Note, howev er, that th is is not a complete list of the items you must configure; these are tips specific to the chained configuration. Refer to the “Configuring SMDI Settings on the VG248”

By default, none of the ports on the VG248 are configured to send SMDI informa tion abou t calls made to those ports. To enable SMDI, you mus t assign the number of SMDI ports a value from 1 to 48. Using fewer than 48 ports for SMDI means th at th e r emainin g p or ts can b e u s ed f o r co nnect in g analog p ho n es , modems, or fax machines.

Setting SMDI Number Length

Tr aditio nal SMDI incl udes cal ler and called party in format ion as 7- digi t number s. If the number is shorter than 7 digits, extra digits (typically zeros) are added to the left. For example, the extension number “12345” becomes “0012345” when sent via SMDI. However, because 7 digits are not enough for external caller ID, an extended SMD I fo rmat is avail abl e t h at uses 10 - di g it nu mb er s .

Most voice mail systems are flexible, supporting either SMDI f ormat. However, some older systems insist on receiving exactly seven digits. Check the voice mail system’s doc umentat ion to d etermin e w h ich se tt in g is most ap propri ate.

You can set the VG248 to output using either 7- or 10-digit numbers. It should match the value required by you r voice ma il system. You c an also set the number length to <unpadded>, which indicates that the voice mail box numbers are always passed unmodified between Cisco CallManager and the analog voice mail system.

However, the SMDI number for mat allows other di gits to be use d. For example , with a SMDI num ber format of 1234567, the extension number 8989 would become 1238989. Zeroes are used for any additional required digits. So, if SMDI number length was 10, the final ex tension num ber would be 00 01238989. If the SMDI number length is set to <unpadded>, this setting has no effect.

Step 1 From the main menu, choose Configure. Step 2 Choose SMDI. Step 3 Choose SMDI number format. Step 4 Enter the required number format.

Validating the SMDI Configuration on the VG248 Devices

You can evaluate the status of the SMDI configuration and diagnose misconfigurations on the VG248 and other VG248 devices chained together. However, this diagnosis cannot detect problems in the configuration of Cisco CallM an ag er, legacy P B X, o r in dividu al ext en s io n’s voice m a il box numb e r s.

A window displays with the results of the diagnosis, indicating any errors or warnings.

Suspending SMDI Port Activity

If you are using the chained configuration and want to temporarily remove one of the VG248 devices or upgrade software on it, you should suspend activity on the SMDI ports before shutting down or restarting the VG248.

By suspending activity, the VG248 waits for the port to become idle, then it tempor ar il y removes the p or t fro m C isco Cal lM an ag er and su sp en ds the por t , preventing any activity on it. Once all the ports have been suspended, traffic from Aysnc 1 is also suspended on the device. SMDI traffic from Async 2 from the previous VG248 device in the chain queues up while this device is suspended. Suspending the device does not affect whether ports are enabled or not; if they were e na bled b ef or e b ei n g su sp en de d, th ey ar e en ab l ed af ter b ei ng r es u me d.
