DiffServ 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 E1/T spans can be designated for 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.
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.
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.
To configure the coder group settings:
1
Open the ‘Coder Group Settings’ screen ( Protocol Management menu > Profile
Definitions submenu > Coder Group Settings option); the ‘Coder Group Settings’
screen is displayed.
