User's Manual 18. Coders and Profiles

To configure Coder Groups:
1. Open the Coder Group Settings page ( Configuration tab > VoIP menu > Coders and
Profiles submenu > Coders Group Settings ).
Figure 18-2: 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 (i.e., format of the RTP payload) for the
coder you selected is dynamic, enter a value from 0 to 120 (payload types of common
coders cannot be modified).
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 next coders (optional).
9. Repeat steps 2 through 8 for the next coder group (optional).
10. Click Submit to apply your changes.
18.3 Configuring Tel Profile
The Tel Profile Settings table allows you to define up to nine configuration profiles for Tel
calls. These profiles are termed
Tel Profiles . The Tel Profile Settings table contains a list of
parameters, which can also be configured globally for all calls using their corresponding
"global" parameters. The only difference between the Tel Profile parameters and the global
parameters regarding description may be their default values.
Tel Profiles provide high-level adaptation when the device interworks between different
equipment and protocols (at both the Tel and IP sides), each of which may require different
handling by the device. Once configured, Tel Profiles can be assigned to specific channels
(trunks). Therefore, Tel Profiles enable you to assign special configuration settings for
device handling of specific calls. For example, if specific channels require the use of the
G.711 coder, you can configure a Tel Profile with this coder and assign it to these
channels. Tel Profiles are assigned to channels in the Trunk Group Table (see Configuring
the Trunk Group Table on page
325 )).
The procedure below describes how to configure Tel Profiles using the Web interface.
