3.3.2.10 Coders and Profiles
The Coders And Profile Definitions submenu includes the following page items:
Coders (see ''Configuring Coders'' on page 139)
Cod
ers Group Settings (see ''Configuring Coder Groups'' on page 140)
Tel Profile Se
ttings (see Configuring Tel Profiles on page 141)
IP Profile Settings (se
e Configuring IP Profiles on page 143)
Implementin
g the device's Profile features provides the device with high-level adaptation
when connected to a variety of equipment (at both Tel and IP sides) and protocols, each of
which requires different system behavior. 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
trunks (channels). For example, specific E1/T1 spans 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.
You can assign different Profiles (behavior) per call, using the call routing tables:
'Outbound IP Routing Table' page (see Configuring the Outbound IP Routing Table on
page 165)
'Inboun
d IP Routing Table' page (see Configuring the Inbound IP Routing Table on
page 172)
In addition, you ca
n 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.
