Feature Guide
[Explanation]
Calls to destinations with leading number "2" or "3" are automatically routed through the IP-GW
ports, designated as trunk group 2.
•
IP-GW (IP Gateway Circuit)
IP address assignment for the local PBX and other PBXs.
[Explanation]
Calls are routed to the IP address of each IP-GW card based on the leading number dialled.
Automatic Rerouting of Calls via a Private IP Network to Public Trunks
When a call via a private IP network cannot be completed successfully, the PBX can automatically attempt
to make the call using a public trunk instead. This provides a backup method of making calls in cases when
private IP network transmission cannot be completed successfully.
[Example]
The leading numbers of extensions accessed through the private IP network are added as entries to the
Quick Dialling table, in addition to being registered as Other PBX Extension Numbers, as shown below:
[Programming Example]
Number to dial to call an extension at another PBX via the private IP network:
7 (TIE line access number) + 20 (PBX Code) + 1011 (extension number)
Number to dial to call that extension using a public trunk:
9 (trunk access number) + 012-345-1011
