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".

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:
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.
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.
To install or remove the VoIP feature card and the DSP modules, you will need the following tools and equipment, which are not included:
The LEDs on the front panel of the VoIP feature card (see Figure 3) indicate the current operating condition of the DSP modules installed on the card. You can observe the LEDs, note any fault condition, and then contact your system administrator or a customer service representative, if necessary. See the "Cisco Connection Online" section for information on contacting customer service. Refer to Table 1 for a description of the LEDs.

This section describes how to remove a VoIP feature card.
To remove the VoIP feature card, perform the following steps:
Step 2 Power OFF the access server.
Step 3 On the rear panel of the access server, locate the VoIP feature card seen in Figure 3.
Step 4 Loosen the two captive screws that secure the VoIP feature card to the chassis until each screw is free of the chassis (see Figure 4).
Step 5 Insert the feature card removal tool so that the slots in each arm of the tool are behind the shoulder of each captive screw, as shown in Figure 5, and carefully pull the removal tool toward you until the VoIP feature card slides free of the chassis.
Step 6 Set the removed VoIP feature card aside on an ESD-preventive mat.
Step 2 On the VoIP feature card, locate the DSP module you will replace (see Figure 6).
Step 3 Orient the VoIP feature card so that the DSP module socket is facing toward you.
Step 4 Gently pry the front edge of the DSP module away from the standoffs and the socket, as indicated by the arrow labeled 1 in Figure 6.
Step 5 When the DSP module is free of the socket, gently pry the back edge of the DSP module away from the other set of standoffs, as indicated by the arrow labeled 2 in Figure 6.
To install a DSP module, first seat the DSP module in the socket, then press all four corners onto their respective standoffs, as shown in Figure 7.
To install a VoIP feature card:
Step 2 Slide the VoIP feature card into the slot until it touches the backplane connector.
Step 3 Align the captive screws with their holes, and then seat the VoIP feature card completely.
Step 4 Tighten the two captive screws (see Figure 8) to secure the VoIP feature card to the chassis.
Step 5 If the access server is configured with fewer than three feature cards, make sure that a blank slot cover is installed over each open slot to ensure proper airflow inside the chassis.
Before you can configure your Cisco router to use VoIP, you must first:
The actual configuration procedure depends entirely upon the topology of your voice network, but, in general, you need to complete the following tasks:
For more detailed examples of command output, see the Voice Over IP for Cisco AS5300 Software Configuration Guide, which includes the following chapters:
Configure the RSVP for voice, multilink PPP interleaving, and RTP header compression to improve the voice network performance for your IP network. Some of the options you will use in the steps listed below depend on the demands of your IP network. For more information about configuring IP, refer to the "Configuring IP" chapter in the Cisco IOS Release 11.2 Network Protocols Configuration Guide, Part 1.
To verify you enabled RSVP and RTP on the interface:
Configure the voice ports as an ISDN PRI group.
To verify you have configured the interfaces correctly:
Note the following information for Serial 0:23 (the first half of the messages):
The second half of the messages display information for Serial 1:23.
Configure the ISDN D channels, which carry the control and signal information for ISDN calls, for each ISDN PRI line.
To verify your D-channel configuration:
1ITU-T1 = International Telecommunication Union Telecommunication Standardization Sector. |
Configure the voice-telephony and voice-network peers for the access server.
Check the validity of your dial peer configuration:
If you are having trouble connecting a call and you suspect the problem is associated with dial peer configuration, try the following:
Configure the voice network data by creating a number expansion table to map (or associate) individual extensions with their full E.164 telephone numbers.
To verify your voice network data configuration:
The following example shows how to test this configuration.
Note In the above example, the num-exp rule maps 31001 to 14085231001 and 14085231001 matches the destination pattern for dial-peer 103.
In this case, there is no number expansion for 7870, and there is no dial-peer with a 7870 destination pattern. The user would have to verify that the number they entered (7870) is correct, that they (optionally) have number expansion for 7870 or some wildcard match for 7870 that expands to the full number they want, and finally a dial peer that matches 7870, or if using num-exp, matches the expansion of 7870.
To download VCWare to your Voice feature card, you need to:
1. Identify Voice feature 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.
2. Check to see that the version of VFC ROM Monitor software is compatible with your installed Cisco IOS image. VFC ROM Monitor version 1.2 requires Cisco IOS image 0.14.1 (1.6 NA1) or later. A compatibility matrix is posted on Cisco Connection Online's Software Center (see Step 3 on page 2 for the URL).
3. Download the software using the appropriate procedure.
