Reasons for Alternative Routing

The Reasons for Alternative Routing screen includes two tables (Tel

Æ

IP and IP

Æ

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

Æ

Tel calls is provided in Q.931 notation. The release reason for Tel

Æ

IP calls is

provided in SIP 4xx, 5xx and 6xx response codes. For Tel

Æ

IP calls an alternative IP

address, for IP

Æ

Tel calls an alternative hunt group.

See

Tel to IP Routing Table

for information on defining an alternative IP address. See

IP to

Hunt Group Routing

for information on defining an alternative hunt group.

You can use this table for example:

For

Tel

Æ

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

Æ

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). See DefaultReleaseCause
in

Table 23

.

The reasons for alternative routing option for Tel

Æ

IP calls, only applies when Proxy

Is not used.

To configure the reasons for alternative routing:

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.

Figure 41

Reasons for Alternative Routing Screen

2

In the IP to Tel Reasons table, from the drop-down list select up to 4 different call failure
reasons that invoke an alternative IP to Tel routing.
