Adding Voice Class Codecs

A voice class codec is the coding scheme used for outgoing calls. Voice class codecs in VRC contain a list of codecs (encoding/decoding scheme) with priorities for using these codecs in the VoIP dial peers.

You can reference a voice class codec for all ingress and egress routes that are used in the dial plan. You must first create the voice class codecs at the region level and then assign them to your routes.

Use this procedure to add voice class codecs to a managed region.

Note: You cannot add voice class codecs to a foreign region.

Procedure

You must be in the Design View to add a voice class codec.

  1. Expand the dial plan tree to view all components.

  2. Locate the region you want to add a voice class codec to.  

  3. Click the Voice Class Codecs tab. The window displays the voice class codecs associated with this region.

  4. Right-click and choose Add from the menu. The Add Voice Class Codecs dialog box appears.

  5. Enter the voice class codec attribute information.

        6.   Click Apply. The voice class codec is added to the region.

The command line interface (CLI) generated for all gateways that terminate routes with this voice class codec shows an output similar to the following example:

voice class codec <tag>

    codec preference 1 <codec_name> [bytes <>]

    codec preference 2 <codec_name> [bytes <>]

 

dial-peer voice <tag> voip

   voice-class codec <voice class codec tag>
