Planning information
The VoIP cards G8-IAX and G3-IAX allow integration of various VoIP standards via an IAX-capable VoIP
server. Therefore, the VoIP cards provide a flexible VoIP interface for IAX connections – e.g. to
G8-VOIPSERV.

NOTES: Installation of a G8-IAX to a GE 300
When using a GE 300 Intercom Server for the G8-IAX card, an interface housing GEI 300 is required
(one GEI 300 per GE 300; the GEI 300 offers place for two interface cards).
The interface housing GEI 300 is connected to the expansion plug of the GE 300, or, if an expansion
housing GEZ 300 is connected there, to the expansion plug of the GEZ 300.
With a GE 300, max. two G8-IAX cards can be used.
For the G8-IAX card, no installation board is required.
The G8-IAX card is connected to the network via the RJ45 jack “Uplink” of the GE 300 motherboard
G3-GEM.
NOTES: Installation of a G3-IAX to a GE 300
The G3-IAX card can be inserted in the slots “1” to “5” of the GE 300 and in the slots “6” to “10” of
the expansion housing GEZ 300 (max. 10 cards per GE 300 incl. GEZ 300).
The G3-IAX card has to be connected to the network via the RJ45 jack “Uplink” of the G3-GEM
motherboard.

System overview
The following section gives a short overview of the basic features of a Gx-IAX card. On the subsequent
pages, the different features of the card are described in detail.
(Phone) calls
Calls in auto-dialler mode
The following example shows an outgoing call from the Intercom system:
Schematic illustration of a call in auto-dialler mode
NOTES: Auto-dialler mode
The auto-dialler mode is used for transfer of calls, e.g. call requests or input messages (control desk
calls) to pre-defined call numbers within the VoIP network.
If an IAX channel is configured as central control desk, initiated calls are stored in the Gx-IAX card
(see also “Call queuing – IAX channel as central control desk” on page 21) and transferred in turn to
the VoIP phones.
The functionality of the auto-dialler mode can also be used for “Audio streaming”.
For further information about auto-dialler mode, see “Auto-dialler mode” on page 19.
