Version 6.4 219 March 2012
SIP User's Manual 16. Coders and Profiles
coders common to both are used. The order of the coders is determined by the
preference.
5. Configure the parameters as required. For more information on each parameter, refer
to the description of the "global" parameter.
6. From the 'Coder Group' drop-down list, select the Coder Group (see 'Configuring
Coder Groups' on page 216) or the device's default coder (see 'Configuring Coders'
on page 215) to which you want to assign the Tel Profile.
7. Click Submit to apply your changes.
8. To save the changes to flash memory, see 'Saving Configuration' on page 482.
16.4 Configuring IP Profiles
The IP Profile Settings page allows you to define up to nine SIP profiles for IP calls (termed
IP Profile). Each IP Profile contains a set of parameters for configuring various behaviors,
for example, used coder, echo canceller support, and jitter buffer. Once configured,
different IP Profiles can be assigned to specific inbound and outbound calls. For example,
specific calls can be assigned an IP Profile that must use the G.711 coder. Thus,
implementing IP Profiles provides high-level adaptation when connected to a variety of
equipment and protocols (at both Tel and IP sides), each of which may require different
system behavior.
The IP Profiles can be used in the following tables:
Outbound IP Routing Table - see 'Configuring Outbound IP Routing Table' on page
271
Inbound IP Routing Table - see 'Configuring Inbound IP Routing Table' on page 279
IP Group table - see 'Configuring IP Groups' on page 195
The IP Profile Settings page conveniently groups parameters according to application to
which they pertain:
Common Parameters - parameters common to all application types
Gateway Parameters - parameters applicable to the GW (gateway) application
Notes:
• For a detailed description of each IP Profile parameter, refer to its
corresponding "global" parameter (configured as an individual
parameter).
• IP Profiles can also be implemented when operating with a Proxy server
(when the AlwaysUseRouteTable parameter is set to 1).
• You can use IP Profiles in the IP Group table, Outbound IP Routing table,
and Inbound IP Routing table. The device selects the IP Profile as
follows:
1) If different IP Profiles (not default) are assigned to these tables, the
device uses the IP Profile with the highest preference level (as set in the
'Profile Preference' field). If they have the same preference level, the
device uses the IP Profile assigned to the IP Group table.
2) If different IP Profiles are assigned to these tables and one table is set
to the default IP Profile, the device uses the IP Profile that is not the
default.
• You can also configure IP Profiles using the ini file table parameter
IPProfile (see 'Configuration Parameters Reference' on page 541).
