Overview

The VoIP capability enables a Cisco access server to carry live voicetrafﬁc(forexample,telephone calls and faxes) over an IP network. The VoIP card is available as a spare or a factory-installed card within the chassis. Use this document if you are:

• Installing or upgrading 6 session voice modules — Part Number AS53-6VOX (DSPM 542)

• Installing 12 session voice modules — Part Number AS53-VOXD (DSPM 549)

The VoIPcard contains multiple digital signal processor (DSP) modules. It uses the Cisco AS5300’s interfaceand local-area network(LAN) or wide-area network (WAN)routing capabilities to provide up to 48/60 channels per Cisco AS5300 universal access server using the AS53-6VOX voice modules, and up to 96/120 channels per Cisco AS5300 universal access server using the AS53-VOXD voice modules.

If you purchased a chassis with this card already installed, go directly to the section “Preparing to Conﬁgure the Software,” page 16.

The VoIP card has two primary applications. The ﬁrst application (see Figure 1) provides a central-site telephony termination facility for VoIP trafﬁc from multiple voice-equipped Cisco AS5300 remote ofﬁce facilities.

Preventing Electrostatic Discharge Damage

Caution Before opening the chassis, ensure that you have discharged all static electricity from your body

and be sure that the power is OFF.

Follow these guidelines when working on equipment powered by electricity:

• Locate the emergency power-OFF switch in the room in which you are working. Then, if an

electrical accident occurs, you can quickly shut the power OFF.

• Disconnect all power before doing the following:

— Installing or removing a chassis — Working near power supplies

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit. Always check.

• Look carefully for possible hazards in your work area, such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

— Use caution; do not become a victim yourself. — Turn OFF power to the system. — Ifpossible, send another person to get medical aid. Otherwise, determine the condition of the

victim and then call for help.

— Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry.It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures.Always follow ESD prevention procedures when removingand replacing cards. Ensure that the chassis is electrically connected to earth ground. Wearan ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between

1 and 10 megohm (Mohm).

General Safety Recommendations

Follow these guidelines to ensure general safety:

• Keep the chassis area clear and dust-free during and after installation.

• Put the removed chassis cover in a safe place.

• Keep tools away from walk areas where you or others could fall over them.

• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll

up your sleeves.

Software Features

This section describes the newest software features of the VoIP card and the DSP modules, which are listed below:

• CODECs

• High-Density DSPs

• DTMF-Relay

For full descriptions of existing software features of the VoIP card and the DSP refer to the Cisco AS5300 Universal Access Server Software Conﬁguration Guide.

Updates to Cisco AS5300 Universal Access Server Module Installation and Software Configuration Guides 13

Software Features

CODECs

Some new compression/decompression (CODECs) has been added to the Cisco AS5300 universal access server. The following table lists the available CODECs with their default packet size (in bytes) and their ranges.

Table 1 Available CODECs CODECs Range

G.711ulaw 40 - 240 160 64 Kbps A separate CODEC for G.729 Annex B is G.711alaw 40 - 240 160 64 Kbps G.723r63 24 - 240 24 6.3 Kbps G.723r53 20 - 240 20 5.3 Kbps G.723ar63 24 - 240 24 6.3 Kbps G.723ar53 20 - 240 20 5.3 Kbps G.726r32 20 - 240 40 32 Kbps G.726r24 15 - 240 30 24 Kbps G.726r16 10 - 240 20 16 Kbps G.728 10 - 240 10 16 Kbps G.729br8 10 - 240 20 8 Kbps G.729r8 pre-ietf 10 - 240 20 8 Kbps G.729r8 10 - 240 20 8 Kbps

included, which adds Annex B functionality to G.729 and a separate CODEC G.723.1 Annex A adds Annex A functionality to G.723.1.

The Annex B functionality added to G.729 and the Annex A functionality added to G.723.1 are the in-built CODEC speciﬁc VAD/CNG functions.

High-Density DSPs

The Cisco AS5300 universal access server DSP/voice modules support the following sessions:

• 542 DSP/voice module (AS53-6VOX) supports 6 voice/fax sessions.

• 549 DSP/voice module (AS53-VOXD) supports 12 voice/fax sessions.

Caution A Cisco AS5300 universal access server can support up to 10 modules of either AS53-6VOX or

AS53-VOXD, but it cannot support both.

DTMF-Relay

DTMF is the tone generated when pressing a digit on a touch-tone phone. This tone is compressed at one end of a call and when it is decompressed at the other can become distorted, depending on the CODEC used. The DTMF-relay feature transports DTMF tones generated after call establishment out-of-bandvia a standard H.323 out-of-band method and a proprietary,RTP-basedmechanism. The principal advantage of this feature is that it transmits DTMF tones with greater ﬁdelity than is possible in-band for most low-bandwidth CODECs such as G.729 and G.723. Without the use of DTMF-relay,calls established with low-bandwidth CODECs may have trouble accessing automated DTMF-based systems such as voicemail, menu-based ACD systems, automated banking systems, and so on.

DTMF-relay is disabled by default when a dial-peer is created.

14 Updates to Cisco AS5300 Universal Access Server Module Installation and Software Conﬁguration Guides

Syntax Description

DTMF-Relay

The dtmf-relay command speciﬁes how an H.323 gateway relays DTMF tones between telephony interfaces and an IP network. Options allow the gateway to forward tones as part of the signal or as part of an H.245 control channel. The no form of this command removes all signaling options and transmits the DTMF tones as part of the audio stream.

dtmf-relay [cisco-rtp] [h245-signal] [h245-alphanumeric] no dtmf-relay

cisco-rtp (Optional) Forwards DTMF tones using RTP protocol with a Cisco proprietary

payload type.

h245-signal (Optional) Forwards DTMF tones using the H.245 “signal” User Input Indication

method. Supports tones 0-9, *, #, and A-D.

h245-alphanumeric (Optional) Forwards DTMF tones using the H.245 “alphanumeric” User Input

Indication method. Supports tones 0-9, *, #, and A-D.

The DTMF-relay syntax is as follows:

• Conﬁguring with DTMF-relay cisco-rtp or h245-signal when sending to dial-peer 103. Enter the

conﬁguration commands, one per line.

5300# conf t 5300(config)# dial-peer voice 103 voip 5300(config-dial-peer)# dtmf-relay cisco-rtp h245-signal 5300(config-dial-peer)# end 5300#

• Conﬁguring the gateway to send DTMF inband (the default) when sending to dial-peer 103.

Enter the conﬁguration commands, one per line.

5300# conf t 5300(config)# dial-peer voice 103 voip 5300(config-dial-peer)# no dtmf-relay 5300(config-dial-peer)# end

The dtmf-relay command determines the outgoing format of relayed DTMF tones. The gateway automatically accepts all formats.

The gateway only sends DTMF tones in the format you specify if the remote device supports it. If the remote device supports multiple formats, the gateway chooses the format based on the following priority:

1 cisco-rtp (highest priority) 2 h245-signal 3 h245-alphanumeric 4 None – DTMF sent inband

Updates to Cisco AS5300 Universal Access Server Module Installation and Software Configuration Guides 15

Preparing to Conﬁgure the Software

Note The cisco-rtp version of DTMF-relay is a proprietary Cisco implementation and as such only

interoperates between two Cisco AS5300 universal access servers running Cisco IOS Release 12.0(2)XH or between Cisco AS5300 universal access servers or Cisco 2600 or 3600 modular access routers running Cisco IOS Release 12.0(5)TPI, or later. Otherwise, the DTMF relay feature will not function and the gateway will send DTMF tones inband.

Preparing to Conﬁgure the Software

Before you can conﬁgure your Cisco AS5300 to use VoIP, you must ﬁrst complete the tasks listed below. If your Cisco AS5300 is already conﬁgured to use VoIP, you can skip this section.

To conﬁgure your Cisco AS5300 to use VoIP:

• Establish a working IP network. For more information about conﬁguring IP, refer to the

“IP Overview,” “Conﬁguring IP Addressing,” and “Conﬁguring IP Services” chapters in the Network Protocols Conﬁguration Guide, Part 1.

• Complete basic conﬁguration for the Cisco AS5300. This includes, as a minimum, the following

tasks:

— Conﬁgure a host name and password for the Cisco AS5300. — Conﬁgure Ethernet 10BaseT/100BaseT interface of your Cisco AS5300 so that it is

recognized as a device on the Ethernet LAN.

— Conﬁgure Cisco AS5300 interfaces for ISDN PRI lines. — Conﬁgure ISDN D channels for each ISDN PRI line.

For more information about these conﬁguration tasks, refer to the Cisco AS5300 Universal Access Server Software Conﬁguration Guide.

• Install the VoIP card (VFC) into the appropriate slot of your Cisco AS5300 access server. Each

VFC can hold up to ﬁve digital signal processor modules, enabling processing for up to 30 B channels with single-density DSPs or 60 B channels with double-density DSPs.

• Complete your company’s dial plan.

• Establish a working telephony network based on your company’s dial plan.

• Integrate your dial plan and telephony network into your existing IP network topology.Merging

your IP and telephony networks depends on your particular IP and telephony network topology. In general, we recommend the following:

— Use canonical numbers wherever possible. It is important to avoid situations where

numbering systems are signiﬁcantly different on different routers or access servers in your network.

— Makerouting and/or dialing transparent to the user by,for example, avoiding secondary dial

tones from secondary switches, where possible.

Upgrading VoIP Card VCWare

To download VCWare to your voice card, you need to:

1 Identify voice cards in the system and determine whether the VFC is in VCWaremode or ROM

monitor mode. This determines how you download software to the VFC. (See “Identify Voice Cards,” page 18.)

2 Check to see that the version of VFC ROM monitor software version 1.2 or 1.3 is compatible

with your installed Cisco IOS image. VCWare version 4.0 (or later) requires Cisco IOS Release 12.0(2)XH, 12.0(5)TPI, or later.

3 Download the software using the appropriate procedure.
