Reasons for Alternative Routing
The Reasons for Alternative Routing screen includes two tables (Tel IP and IP Tel).
Each table enables you to define up to four different release reasons. If a call is released
as a result of one of these reasons, the gateway tries to find an alternative route to that
call. The release reason for IP Tel calls is provided in Q.931 notation. The release reason
for Tel IP calls is provided in SIP 4xx, 5xx and 6xx response codes. For Tel IP calls an
alternative IP address, for IP Tel calls an alternative hunt (analog modules) or trunk
(digital modules) group.
Refer to Section
Refer to the Section
group.
You can use this table, for example:
For Tel IP calls, when there is no response to an INVITE message (after INVITE
retransmissions), and the gateway then issues an internal 408 'No Response' implicit
release reason.
For IP Tel calls, when the destination is busy, and release reason #17 is issued or
for other call releases that issue the default release reason (#3). Refer to
'DefaultReleaseCause' in
