AltRouteCauseTel2IP
AltRouteCauseTel2IP = <SIP Call failure reason from IP>
For example:
AltRouteCauseTel2IP = 408 (Response timeout).
AltRouteCauseTel2IP = 486 (User is busy).
Note: This parameter can appear up to 4 times.
AltRouteCauseIP2Tel
AltRouteCauseIP2Tel = <Call failure reason from Tel>
For example:
AltRouteCauseIP2Tel = 3 (No route to destination).
AltRouteCauseIP2Tel = 17 (Busy here).
Note:
This parameter can appear up to 4 times.
5.5.6 Configuring the Profile Definitions
Utilizing the Profiles feature, the MediaPack provides high-level adaptation when
connected to a variety of equipment (from both Tel and IP sides) and protocols, each of
which requires a different system behavior. Using Profiles, users can assign different
Profiles (behavior) on a per-call basis, using the Tel to IP and IP to Hunt Group Routing
tables, or associate different Profiles to the gateway’s endpoint(s). The Profiles contain
parameters such as Coders, T.38 Relay, Voice and DTMF Gains, Silence Suppression,
Echo Canceler, RTP DiffServ, Current Disconnect and more. The Profiles feature allows
users to tune these parameters or turn them on or off, per source or destination routing
and/or the specific gateway or its ports. For example, specific ports can be designated to
have a profile which 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 are applied.
Note: The default values of the parameters in the Tel and IP Profiles are
identical to the Web/ini file parameter values. If a value of a parameter
is changed in the Web/ini file, it is automatically updated in the Profiles
correspondingly. After any parameter in the Profile is modified by the
user, modifications to parameters in the Web/ini file no longer impact
that Profile.
5.5.6.1 Coder Group Settings
Use the Coder Group Settings screen to define up to four different coder groups. These
coder groups are used in the Tel and IP Profile Settings screens to assign different coders
to Profiles.
For each group you can define the first to fifth preferred coders (and their attributes) for the
gateway. The first coder is the highest priority coder and is used by the gateway whenever
possible. If the far end gateway cannot use the coder assigned as the first coder, the
gateway attempts to use the next coder and so forth.
