Configuring Coders - AudioCodes MP-124 User Manual

SIP User's Manual
Each Profile contains a set of parameters such as coders, T.38 Relay, Voice and DTMF
Gain, Silence Suppression, Echo Canceler, RTP DiffServ, Current Disconnect and more.
The Profiles feature allows you to customize these parameters or turn them on or off, per
source or destination routing and/or per the device's endpoints (channels). For example,
specific ports can be assigned a Profile that always uses G.711.
Each call can be associated with one or two Profiles - Tel Profile and/or IP Profile. If both IP
and Tel profiles apply to the same call, the coders and other common parameters of the
preferred Profile (determined by the Preference option) are applied to that call. If the
Preference of the Tel and IP Profiles is identical, the Tel Profile parameters take
precedence.
Notes:

3.3.4.4.1 Configuring Coders

The 'Coders' page allows you to configure up to five coders (and their attributes) 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:
Version 5.8
•
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.
•
If you modify a parameter in its primary configuration page (orini file) that
also appears in the profile pages, the parameter's new value is
automatically updated in the profile pages. However, once you modify
any parameter in the profile pages, modifications to parameters in the
primary configuration pages (orini file) no longer impact that profile
pages.
•
For a list of supported coders, refer to the ini file parameter table
CoderName, described in ''SIP Configuration Parameters'' on page 252.
You can also configure the Coders table using this parameter.
•
For defining groups of coders (which can be assigned to Tel and IP
Profiles), refer to ''Configuring Coder Groups'' on page 107.
•
The device always uses the packetization time requested by the remote
side for sending RTP packets.
•
For an explanation on V.152 support (and implementation of T.38 and
VBD coders), refer to ''Supporting V.152 Implementation'' on page 403.
