3.3.5.10.1 Configuring Reasons for Alternative Routing
The 'Reasons for Alternative Routing' page allows you to define up to four different call
release (termination) reasons for IP-to-Tel call releases and for Tel-to-IP call releases. If a
call is released as a result of one of these reasons, the device tries to find an alternative
route for that call. The device supports up to two different alternative routes.
The release reasons depends on the call direction:

Release reason for IP-to-Tel calls: provided in Q.931 notation. As a result of a
release reason, an alternative Trunk Group is provided. For defining an alternative
Trunk Group, refer to ''Configuring the Inbound IP Routing Table''
This call release reason type can be configured, for example, 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 the parameter DefaultReleaseCause.

Release reason for Tel-to-IP calls: provided in SIP 4xx, 5xx, and 6xx response
codes. As a result of a release reason, an alternative IP address is provided. For
defining an alternative IP address, refer to ''Configuring the Outbound IP Routing
Table'' on page
This call release reason type can be configured, for example, when there is no
response to an INVITE message (after INVITE re-transmissions), the device issues an
internal 408 'No Response' implicit release reason.
The device also plays a tone to the endpoint whenever an alternative route is used. This
tone is played for a user-defined time, configured by the ini file parameter
AltRoutingToneDuration.
