Table 19-1: Coders Table Parameter Descriptions
Defines the coder.
Note: Each coder type (e.g., G.729) can be configured only once
in the table.
Defines the packetization time (in msec) for the coder. The
packetization time determines how many coder payloads are
combined into a single RTP packet.
Defines the bit rate (in kbps) for the coder.
Defines the payload type if the payload type (i.e., format of the
RTP payload) for the coder is dynamic.
Enables silence suppression for the coder.

[0] Disable (Default)

[1] Enable

[2] Enable w/o Adaptation =Applicable only to G.729.
Notes:

If silence suppression is not configured for a coder, the
settings of the EnableSilenceCompression parameter is used.

If G.729 is configured with silence suppression disabled, the
device includes 'annexb=no' in the SDP of the relevant SIP
messages. If silence suppression is enabled or set to Enable
w/o Adaptations, 'annexb=yes' is included. An exception to
this logic is when the remote gateway is Cisco equipment
(IsCiscoSCEMode).
