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 4 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 trunk group.
See Table 24 for information on defining an alternative IP address. See the
information on defining an alternative trunk 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.
