SIP User's Manual
Release reason for Tel-to-IP calls: Reason for call release on the IP side, 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, see
''Configuring Outbound IP Routing Table'' on page 165. 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 plays a tone to the endpoint whenever an alternative route is used. This tone is
played for a user-defined time, configured by the AltRoutingToneDuration parameter.
Notes:
To configure reasons for alternative routing:
1. Open the 'Reasons for Alternative Routing' page (Configuration tab > VoIP menu >
GW and IP to IP submenu > Routing submenu > Alternative Routing Reasons).
2. In the 'IP to Tel Reasons' group, select up to five different call failure reasons that
invoke an alternative IP-to-Tel routing.
3. In the 'Tel to IP Reasons' group, select up to five different call failure reasons that
invoke an alternative Tel-to-IP routing.
4. Click the Submit button to save your changes.
5. To save the changes to flash memory, see ''Saving Configuration'' on page 336.
