5.8.4.5 Reasons for Alternative Routing
The Reasons for Alternative Routing screen includes two tables (TelIP and IPTel). 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 (received in Q.931 presentation), the gateway tries to find an alternative route to
that call. For TelIP calls an alternative IP address, for IPTel calls an alternative hunt group.
Refer to ‘Tel to IP Routing’ on page 74 for information on defining an alternative IP address. Refer
to the ‘IP to Hunt Group Routing Table’ on page 77 for information on defining an alternative hunt
group.
Note: The reasons for alternative routing option for TelIP calls only applies when Gatekeeper
isn’t used.
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); the ‘Reasons for Alternative
Routing’ screen is displayed.
