Cisco AS5300 Voice-over-IP Feature Card Installation and Configuration

Product Numbers: AS53-CC-VOX=, AS53-6VOX=, AS53-CC-VOX, AS53-6VOX

The Voice-over-IP (VoIP) Feature Card is a coprocessing card and software package that adds VoIP capabilities to Cisco AS5300 universal access servers. The VoIP capability enables a Cisco router to carry live voice traffic (for example, telephone calls and faxes) over an IP network. The VoIP feature card is available as a spare or a factory-installed card within the chassis.

The VoIP feature card contains multiple digital signal processor (DSP) modules. It uses the Cisco AS5300's quad T1/E1 Public Switched Telephone Network (PSTN) interface and local-area network (LAN) or wide-area network (WAN) routing capabilities to provide up to a 48/60 channel gateway for VoIP packetized voice traffic to/from T1/E1 time-division multiplexing (TDM) traffic. Major applications of the VoIP feature cards include toll bypass, remote PBX presence over WANs, unified voice/data trunking, and plain old telephone service (POTS) internet phone gateway. If you purchased a chassis with this card already installed go directly to "Prerequisites to Configuration".

Applications

VoIP offers the following benefits:

• Toll bypass

• Remote PBX presence over WANs

• Unified voice/data trunking

• POTS-Internet telephony gateways

The VoIP feature 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.

The second application (see Figure 2) uses the VoIP feature card as a PSTN gateway for Internet telephone traffic. This leverages the standardized use of H.323-based Internet telephone client applications.

Hardware Features

The basic hardware features of the VoIP feature card and the DSP modules are described in the following sections.

VoIP Feature Card

The VoIP feature card is a voice processing card that resides in one of the slots in the Cisco AS5300 universal access server. Up to five DSP modules can be installed onto the Voice feature card to perform voice processing for up to 30 B channels.

• CPU: MIPS 4700 100 MHz

• Support chipset: GT-64010 system controller

• DRAM: Standard 72 pin SIMM (4, 8, 16 MB)

• Flash: Cisco proprietary Flash 80 pin SIMM

• Five DSP module sockets

DSP Modules

The DSP module provides voice compression and packetization services to the Voice feature card in a configurable and expandable fashion.

• 6 DSPs per DSP module, use 4 DSP modules for T1 applications and 5 DSP modules for E1 applications

• Uses TI TMS320C542 50 MHz

• DSP SRAM: 128 Kwords (16 bit)

Prerequisites

You need to have available the Cisco Documentation CD-ROM, printed documents or web access to: Cisco AS5300 Universal Access Server Software Configuration Guide, Cisco AS5300 Universal Access Server Hardware Installation Guide, Voice Over IP for Cisco AS5300 Software Configuration Guide, and the Regulatory Compliance and Safety Information document for the AS5300 universal access server.

Before you can configure your Cisco AS5300 to use Voice over IP, you must first:

• Install the VoIP feature 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. For more information about the physical characteristics of the VFCs or DSP modules, refer to the previous section "Hardware Features"of this document.

• 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--for example, avoid secondary dial tones from secondary switches, where possible.

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

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.

Safety with Electricity

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

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.

  • 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.

Software Requirements

In the Cisco AS5300 universal access server, the VoIP feature card and the DSP modules require Cisco IOS Release IP Plus SF53CP-11.3.2N or higher.

Tips

If you are having trouble:

• Enter the debug isdn q931 command and look at the Cause i line if voice calls are being rejected. If this line states "Bearer capability not presently available," then you may need to use the isdn incoming voice modem command.

5300#	 debug isdn q931
 ISDN Se3:23: RX <-  SETUP pd = 8  callref = 0x0001
   Bearer Capability i = 0x8090A2
   Channel ID i = 0xA98381
   Net Specific Fac i = 0x0480323535E1
   Calling Party Number i = 0x0080, '40001'
   Called Party Number i = 0x80, '99'
 ISDN Se3:23: TX - RELEASE_COMP pd = 8 callref = 0x8001
   Cause i = 0x80BA - Bearer capability not presently available

• If dialing cannot occur, check the configuration by entering the debug isdn q931 command. When you finish viewing the messages, enter no debug isdn q931 to turn off the messages. See Table 2 for explanations of the error messages.

5300# debug isdn q931

ISDN Event: Hangup call to call id 0xCE2 on dsl 2

Step 4: Configuring the Dial Peers

Configure the voice-telephony and voice-network peers for the access server.

Verify

Check the validity of your dial peer configuration:

• Enter the show dial-peer voice command to verify that the data is configured correctly. Note that you should use this command only if you have relatively few dial peers configured.

5300# sh dial-peer voice 4
 VoiceEncapPeer4
   tag = 4, destination-pattern = `4....',
   answer-address = `',
   group = 4, Admin state is up, Operation state is up
   incoming called-number = `', connections/maximum = 0/unlimited
   type = pots, prefix = `4',
     session-target = `', voice-port = 3:D, direct-inward-dial = disabled
   Connect Time = 38992627, Charged Units = 0
   Successful Calls = 0, Failed Calls = 35818
   Accepted Calls = 35818, Refused Calls = 0
   Last Disconnect Cause is "1C"
   Last Disconnect Text is "invalid number."
   Last Setup Time = 3787365

Tips

If you are having trouble connecting a call and you suspect the problem is associated with dial peer configuration, try the following:

• Ping the associated IP address to confirm connectivity. If you cannot successfully ping your destination, refer to the "Configuring IP" chapter in the Cisco IOS Release 11.2 Network Protocols Configuration Guide, Part 1.

• Enter the show dial-peer voice command or the test dialplan number command or both on the local and remote routers to verify the data is configured correctly.

• If you have configured number expansion, enter the show num-exp command to check that the partial number on the local router maps to the correct full E.164 telephone number on the remote router.

• The codec value must be configured the same on both the voice-telephony peer and the voice-network peer.

• Enter the debug vpm spi command to verify the output dial string the router dials is correct.

• Enter the debug cch323 rtp command to check RTP packet transport.

• Enter the debug cch323 h245 command to check logical channel negotiation.

• Enter the debug cch323 h225 command to check the call setup.

Step 5: Configuring Voice Network Data

Configure the voice network data by creating a number expansion table to map (or associate) individual extensions with their full E.164 telephone numbers.

Configure

Verify

To verify your voice network data configuration:

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, then begin the following steps.

Verify

To check that you have successfully downloaded the software:

• Enter the show vfc slot_number directory command to verify that the VCWare is in the Flash memory. Only one filename should appear. If this command times out, start over with "Identify Voice Cards."

5300# show vfc 1 dir
Files in slot 1 VFC flash:
	File Name 	Size (Bytes)
1.	vcw-vfc-mz.1.0.bin 	291292

• Enter the show vfc slot_number default-file and show vfc slot_number cap-list commands to verify that the DSPWare is unbundled and the default file list and cap-list are initialized.

5300# show vfc 1 def (full word is default-file)
