Automatic Rerouting Of Voip Calls To Public Trunks - Panasonic KX-TDE100 Features Manual

1.30.2 Voice over Internet Protocol (VoIP) Network

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)
PBX-1
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
[Quick Dialling Table]
Quick Dialling No.
720
If the call cannot be completed using the VoIP network, and the dialled leading number is found in the Quick
Dialling Table, the call will be automatically rerouted to a trunk as specified by the corresponding destination
number.
When a call is made using the VoIP network, if the PBX does not receive a reply from the other PBX within
about 4 seconds of making the call, or an error is returned, the call is rerouted to a public trunk as specified.
Sending Faxes Through the Network
Through system programming, it is possible to select whether faxes are sent using analogue or T.38 protocol
signals.
