SIP User's Manual 5. Web-based Management
You can use the 'Reasons for Alternative Routing' screen in the following example
scenarios:
îš„ For Tel-to-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.
îš„ For IP-to-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 'General Parameters' on page 103.
Note: The reasons for alternative routing option for TelÆIP calls only apply when a
Proxy isn't used.
For configuring this table, you can also use the ini file parameters AltRouteCauseTel2IP
and AltRouteCauseIP2Tel (refer to 'Number Manipulation and Routing Parameters' on
page 318).
¾ To configure the reasons for alternative routing, take these 5
steps:
1. Open the 'Reasons for Alternative Routing' screen (Protocol Management menu >
Routing Tables submenu > Reasons for Alternative Routing option).
Figure 5-20: Reasons for Alternative Routing Screen
