3.4.5.4.3 IP to Trunk Group Routing
The 'IP to Trunk Group Routing Table' page provides a table for routing incoming IP calls
to groups of channels (BRI,E1/T1 B-channels, and Mediant 1000 FXS/FXO endpoints)
called Trunk Groups. You can add up to 24 entries in the table.
The IP-to-Tel calls are routed to Trunk Groups according to any of the following (or a
combination thereof):
Destination phone prefix
Source phone prefix
Source IP address
Once the call is routed to the specific Trunk Group, the call is sent to the device's channels
pertaining to the Trunk Group. The specific channel within the Trunk Group to which the
call is sent is determined according to the Trunk Group's channel selection mode. This
mode is defined per Trunk Group in the 'Trunk Group Settings' page (refer to ''Configuring
the Trunk Group Settings'' on page 228) or for all Trunk Groups in the 'SIP General
Parameters' page (refer to ''SIP General Parameters'' on page 134) using the global
parameter ChannelSelectMode. If a mode is not specified for a Trunk Group, then this
global parameter applies. Trunk Groups can be used for FXO and FXS channels, but they
are typically used for FXO interfaces (only Mediant 1000).
Trunk Group ID's are assigned to the device's channels in the 'Trunk Group Table' page
(refer to "Configuring the Trunk Group Table" on page 226).
Notes:
SIP User's Manual
A read-only field representing the Quality of Service of the destination IP
address:
n/a = Alternative Routing feature is disabled.
OK = IP route is available.
Ping Error = No ping to IP destination; route is not available.
QoS Low = Bad QoS of IP destination; route is not available.
DNS Error = No DNS resolution (only when domain name is used
instead of an IP address).
An optional Charge Code (1 to 25) can be applied to each routing rule to
associate it with an entry in the Charge Code table (refer to "Charge Codes
Table" on page 183).
Note: This column is applicable only to Mediant 1000.
•
When a release reason, defined in the 'Reasons for Alternative IP to Tel
Routing' table (refer to ''Reasons for Alternative Routing'' on page 209) is
received for a specific IP-to-Tel call, an alternative Trunk Group for that
call is available. To associate an alternative Trunk Group to an incoming
IP call, assign it with an additional entry in the 'IP to Trunk Group Routing'
table (repeat the same routing rules with a different Trunk Group ID).
•
You can also configure the 'IP to Trunk Group Routing' table using the ini
file table parameter PSTNPrefix (refer to ''Number Manipulation and
Routing Parameters'' on page 364).
