CLI Commands
set
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: The G.729 feature is protected by a software key. Until an
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.
Syntax: set {cmg_voice-addr} algorithm preference
{alg-choice1} [alg-choice2] [alg-choice3]...
Example: set 2:1:1:1-24 algorithm preference g726_32 g711mu
The example will set the algorithm preference G.726-32 with a second choice as
G711 mu-law for voice channels 1 through 24 on the CMG card in slot 2.
{cmg_voice-addr}
In the form {slot:voip:port}.
{alg-choice1}
[alg-choice2] through [alg-choice6]
These optional fields should be listed in order of preference. Algorithms are used from the
list above and are only listed once.
