Usage Guidelines
Use this commands to create a list of supported dynamic audio and video codecs in the system. When a request
is received by the CSCF, the SDP fields in the message are checked to determine the codec being used. The
codec in the SDP fields must match a codec in the allowed codec list or the CSCF rejects the request.

Examples
The following command adds the GSM-EFR codec to the allowed dynamic codec list:
