25.7.2 Alternative Routing to an IP Destination upon a Busy Trunk
The Forward on Busy Trunk Destination table lets you configure alternative routing rules for
forwarding (i.e., call redirection) IP-to-Tel calls to an alternative IP destination using SIP
3xx responses. These rules are used upon the following:

Trunk Group has no free channels (i.e., “busy”).

This feature is configured per Trunk Group. The alternative destination can be defined as a
host name or as a SIP Request-URI user name and host part (i.e., user@host). For
example, the below configuration forwards IP-to-Tel calls to destination user “112” at host
IP address 10.13.4.12, port 5060, using transport protocol TCP, if Trunk Group ID 2 is
unavailable:
ForwardOnBusyTrunkDest 1 = 2, 112@10.13.4.12:5060;transport=tcp;
When configured with user@host, the original destination number is replaced by the user
part.
The device forwards calls using this table only if no alternative IP-to-Tel routing rule has
been configured in the Inbound IP Routing table or alternative routing fails and the
following reason(s) in the SIP Diversion header of 3xx messages exists:

“out-of-service” - all trunks are unavailable/disconnected
