Overview

The VoIP capability enables a Cisco access server to carry live voice traffic (for example, 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 VoIP card contains multiple digital signal processor (DSP) modules. It uses the Cisco AS5300's interface and 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 17.

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

Figure 1 VoIP Card as Central Site

The second application (see ) uses the VoIP card as a PSTN gateway for Internet telephone traffic. This leverages the standardized use of H.323-based Internet telephone client applications.

•If an electrical accident occurs, proceed as follows:

•Use caution; do not become a victim yourself.

•Turn OFF power to the system.

•If possible, 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 removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an 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.

•Wear safety glasses when working under any conditions that might be hazardous to your eyes.

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

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-band via a standard H.323 out-of-band method and a proprietary, RTP-based mechanism. 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.

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

Syntax Description

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

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.

•Make routing and/or dialing transparent to the user by, for example, avoiding secondary dial tones from secondary switches, where possible.

•Contact your PBX vendor for instructions on how to reconfigure the appropriate PBX interfaces.

Identify Voice Cards

Use the following steps to identify the voice cards in the system and determine whether the VFC is in VCWare mode or ROM monitor mode. This determines how you download software to the VFC. If there is not VCWare loaded on the VFC, you can use the ROM monitor mode to download the VCWare. Otherwise the VCWare mode is active.

5300# show vfc <0-2> board

Determine the number of voice cards in the system, the slot number for each card, and the VFC mode (VCWare or ROM monitor) in which you are running.

The VFC mode is indicated as follows:

•VCWARE running for VCWare mode
or

•ROMMON for ROM monitor mode

Note the location and the mode type for each voice card. You will need this information when you upgrade the VCWare.


Go to one of the following sections to continue the procedure to upgrade the VCWare:

•"Replace Firmware with VCWare in VCWare Mode," if your voice card is running in VCWare mode
or

•"Replace Firmware with VCWare in ROM Monitor Mode," if your voice card is running in ROM monitor mode.

Replace Firmware with VCWare in VCWare Mode

Configure

Use the steps that follow to download new voice software if your voice card is running in VCWare mode. When downloading from a diskette, first copy the software from the diskette to a TFTP server. After the software is on the TFTP server, begin the following steps.

Caution   
Erasing the VFC files can result in system outage or the corruption of your VFC board. Check to ensure that the correct version of software resides on your TFTP server before continuing.
