5.5.4.5 Reasons for Alternative Routing
The Reasons for Alternative Routing screen includes two tables (TelÆIP and IPÆTel).
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 TelÆIP calls an alternative IP address, for IPÆTel calls an
alternative trunk group.
Refer to Section 5.5.4.2 on page 98 for information on defining an alternative IP address.
Refer to the Section 5.5.4.3 on page 100 for information on defining an alternative trunk
group.
Note: The reasons for alternative routing option for TelÆIP calls only apply when
Gatekeeper isn’t used.
