Set (Router-Voice) Algorithm Preference - Black Box Compact T1 MT850A User Manual

set (router-voice) algorithm preference

Use the set (router-voice) algorithm preference command to specify the list of voice coding
algorithms which will be supported for VoIP calls, on the specified voice channel(s). More than
one algorithm can be listed, and they should be in order of preference. The default algorithm
preference list contains all supported codecs in the order shown below. This command takes
effect immediately, and applies to the CMG Router card only.
NOTE:
appropriate key is entered to enable this codec will not appear in the
available codec list used in the MGCP and DSP messages and negotiation.
The command, however, will still succeed to allow for pre-configuration.
