NOTES: PABX mode
In PABX mode, it is possible to make a phone call between Intercom station and VoIP phone.
By pre-dialling the respective call number of the channel of the Gx-IAX card, it is possible to dial to a
telephone within the VoIP network.
It is possible to dial directly to a VoIP phone from an Intercom station without the need for pre-dialling
the IAX channel (
see “Phone call by direct outward dialling” on page 26
.
