Gateway Settings List
1. IP-GW(1): GW Group-1
2. IP-GW(2): GW Group-1
3. IP-GW(3): GW Group-1
4. IP-GW(4): GW Group-2
5. IP-GW(5): GW Group-2
When "123XXX" is dialled, the call is routed to GW Group-1. However the lowest-numbered device (IP-
GW(1)) is busy or not available, so the call is rerouted to IP-GW(2).
Note
For information about assigning groups when using the IP-GW card, refer to the Programming Guide
of the VoIP Gateway Card.
Automatic Rerouting of VoIP Calls to Public Trunks
When a VoIP call 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 IP network
transmission cannot be completed successfully.
[Example]
Telephone Company
(area code: 098)
Extn.1000
Dials
PBX code: 30
"7-20-1011".
The leading numbers of extensions accessed through the VoIP 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 using VoIP 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
