menu > Profile Definitions submenu > Coder Group Settings page item).
Figure 3-83: Coder Group Settings Page
2. From the 'Coder Group ID' drop-down list, select a coder group ID.
3. From the 'Coder Name' drop-down list, select the first coder for the coder group.
4. From the 'Packetization Time' drop-down list, select the packetization time (in msec)
for the coder. The packetization time determines how many coder payloads are
combined into a single RTP packet.
5. From the 'Rate' drop-down list, select the bit rate (in kbps) for the coder you selected.
6. In the 'Payload Type' field, if the payload type for the coder you selected is dynamic,
enter a value from 0 to 120 (payload types of 'well-known' coders cannot be modified).
The payload type identifies the format of the RTP payload.
7. From the 'Silence Suppression' drop-down list, enable or disable the silence
suppression option for the coder you selected.
8. Repeat steps 3 through 7 for the second to fifth coders (optional).
9. Repeat steps 2 through 8 for the second to fourth coder groups (optional).
10. Click the Submit button to save your changes.
11. To save the changes to flash memory, refer to ''Saving Configuration'' on page 265.
