Coders

From the Coders screen you can configure the first to fifth preferred coders (and their
attributes) 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.
You can also configure the Coders table using the ini file parameter CoderName (refer to
Section 6.5.7
To configure the gateway's coders, take these 9 steps:
1. Open the 'Coders' screen (Protocol Management menu > Protocol Definition
submenu > Coders option); the 'Coders' screen is displayed.
2. From the Coder Name drop-down list, select the coder you want to use. For the full list
of available coders and their corresponding attributes, refer to
Note: Each coder can appear only once.
3. From the Packetization Time drop-down list, select the packetization time (in msec) for
the coder you selected. The packetization time determines how many coder payloads
are combined into a single RTP packet.
Note 1: If not specified, the ptime gets a default value.
Note 2: The ptime specifies the packetization time the gateway expects to receive.
The gateway always uses the ptime requested by the remote side for sending RTP
packets.
4. From the Rate drop-down list, select the bit rate (in kbps) for the coder you selected.
