In addition, you can associate different Profiles per the channels.
Notes:
• The default values of the parameters in the 'Tel Profile Settings' and 'IP
Profile Settings' pages are identical to their default values in their
respective primary configuration page ("global" parameter).
• If you modify a global parameter in its primary configuration page (or ini
file) that also appears in a profile pages, the parameter's new value is
automatically updated in the profile page. However, once you modify any
parameter in a profile page, modifications to parameters in the primary
configuration pages (or ini file) no longer impact that profile page.
3.3.2.7.1 Configuring Coders
The 'Coders' page allows you to configure up to 10 coders for the device. The first coder in
the list has the highest priority and is used by the device whenever possible. If the far-end
device cannot use the first coder, the device attempts to use the next coder in the list, and
so on.
Notes:
• For a list of supported coders and for configuring coders using the ini file,
refer to the ini file parameter table CodersGroup, described in SIP
Configuration Parameters.
• For defining groups of coders (which can be assigned to Tel and IP
Profiles), see ''Configuring Coder Groups'' on page 119.
• For an explanation on V.152 support (and implementation of T.38 and
VBD coders), see ''Supporting V.152 Implementation'' on page 253.
¾ To configure the device's coders:
1. Open the 'Coders' page (Configuration tab > VoIP menu > Coders And Profiles
submenu > Coders).

2. From the 'Coder Name' drop-down list, select the required coder.
3. From the 'Packetization Time' drop-down list, select the packetization time (in msec)
for the selected coder. The packetization time determines how many coder payloads
are combined into a single RTP packet.
4. From the 'Rate' drop-down list, select the bit rate (in kbps) for the selected coder.
