6.2.4.3 Coder Group Profiles
The Coder Group Profiles option opens the 'Coder Groups' screen. This screen allows
you to configure the first to fifth preferred coders (and their corresponding ptimes) for the
gateway. The first coder is the highest priority coder and is used by the gateway whenever
possible. If the far end gateway cannot use the coder assigned as the first coder, the
gateway attempts to use the next coder and so forth.
The gateway supports the following coders:
 G.711 A-law 64 kbps supporting packetization period of 10, 20, 30, 40, 50, 60, 80,
100, and 120 msec
