User's Manual 22. Routing
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 in the SIP Diversion header of 3xx messages exists:

"unavailable": All FXS / FXO lines pertaining to a Hunt Group are busy or unavailable
Note: You can also configure the Forward on Busy Trunk Destination table using
the table ini file parameter, ForwardOnBusyTrunkDest.

To configure Forward on Busy Trunk Destination rules:
1. Open the Forward on Busy Trunk Destination page ( Configuration tab > VoIP menu
> GW and IP to IP > Routing > Forward on Busy Trunk ).
Figure 22-6: Forward on Busy Trunk Destination Page
The figure above displays a configuration that forwards IP-to-Tel calls destined for
Hunt Group ID 1 to destination IP address 10.13.5.67 if the conditions mentioned
earlier exist.
2. Configure the table as required, and then click Submit to apply your changes.
3. Save the changes to the device's flash memory with a device reset (see 'Saving
Configuration' on page
324 ).
