Difference between outgoing and incoming
In auto-dialler mode as well as in PABX mode, outgoing and incoming (phone) calls are possible.
Call direction at outgoing and incoming (phone) calls
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).
For further information about PABX mode, see “PABX mode” on page 26.
NOTE: Functions via VoIP phones
At the respective VoIP phone, Intercom functions can be carried out via the keypad (see also “After

Speech channels
Individual configuration per channel
It is possible to carry out a separate individual configuration for each channel of the Gx-IAX card. This
means, a separate speech connection to a VoIP server with individual features is available for each
channel.
Example G8-IAX-4
The several channels of the G8-IAX-4 card are configured as follows:
1st channel: “
Auto-dialler mode”with 6 pre-configured call numbers
2nd channel: “PABX mode”with password
3rd channel: “
Auto-dialler mode”with 8 pre-configured call numbers and password
4th channel: used as “recorder” for “
Audio mixing for speech recording”
Dynamic channel allocation
The dynamic channel allocation applies to incoming calls to the Intercom system.
Schematic illustration of the dynamic channel allocation
NOTES: Dynamic channel allocation
A call from a VoIP phone to the Intercom system is always built up via the 1st channel of the respec-
tive Gx-IAX card.
If the 1st channel is busy (e.g. because of an existing conversation via this channel), the call will au-
tomatically built up via the next idle channel. This also means, the configurations defined for this
channel become effective for this call (e.g. see “Example G8-IAX-4”).

Trunk connection G8-IAX / G3-IAX
16 3.0/0616
Trunk connection
The coupling between Intercom Server and VoIP server is called trunk connection. In order to establish
this connection, pre-configurations of the VoIP server and via CCT 800 are required. This required con-
figuration as well as additional planning information are specified in the following sections.
Planning information for IAX trunk connection
Prior to the establish and configuration of a trunk connection between Intercom Server and VoIP server,
the following questions shall be clarified:
Is the IAX2 protocol supported by the existing VoIP server?
Does the respective VoIP server support the codecs G.711 a-law or G.722?
Is plain text or MD5 as authentication method possible?
How many speech channels (IAX channels) are required?
Which features in the Intercom system are required (e.g. central control desk functions or executive-
secretary transfer chain)?
Registration on VoIP server
The user name and password defined on the VoIP server and the required settings for the network con-
nection have to be configured via CCT 800 for each Gx-IAX card as well (see “Configuration CCT 800 –
trunk connection” on page 18).
NOTE: Feature levels
In order to be able to operate the desired features, corresponding features levels (“B”, “C” or “D”)
of the respective cards are required. These feature levels are listed in the manual “PRO 800
Basic”.
GOOD TO KNOW: VoIP – server registration
Similar to VoIP phones, the different Gx-IAX cards have to be registered on the VoIP server:
The registration of the Gx-IAX card is carried out by means of user name and password (“User
Account”).
Additionally, an entry in the “dial plan” on the VoIP server has to be carried out for each Gx-IAX card.
This means, a dial prefix for each card has to be defined in order to be able to build up a call from the
VoIP phone to the respective Gx-IAX card.
ATTENTION: User name and password
Observe the following for definition of user name and password:
User name: alphanumeric, max. 16 digits
Password: alphanumeric, max. 16 digits

G8-IAX / G3-IAX Trunk connection
3.0/0616 17
Overview and example
The schematic illustration below shows an example with the following specifications:
Three Gx-IAX cards – each registered at the VoIP server with a separate “user account”, i.e. with a
separate user name and password:
Card A: user account A (user name & password A)
Card B: user account B (user name & password B)
Card C: user account C (user name & password C)
For each user account (for each Gx-IAX card), a separate dial prefix is defined (e.g. “20”, “21 and
“22”).
Schematic example illustration
By means of the corresponding dial prefix, it is possible to initiate a call from a VoIP phone to each
Gx-IAX card:
Call to card Aby using prefix “20”
Call to card B: by using prefix “21”
Call to card Cby using prefix “22”
NOTE: Further information
For further information regarding incoming and outgoing calls from the Intercom system, see the

Do not change the default settings (“10240 Kbit”) in the drop-down lists Bandwidth Kbit and
Databandwidth Kbit. This means, do not configure any limitation.

G8-IAX / G3-IAX Auto-dialler mode
3.0/0616 19
Auto-dialler mode
A call from an Intercom station or an input message will be transferred to a pre-defined call number. If
the call is not answered by this telephone or if the telephone is busy, the call will be transferred to an-
other call number after a configurable time. The order, in which the call numbers shall be dialled, is
defined in “dialling sequences“.
Call numbers and dialling sequences
Up to 8 call numbers can be defined, which will be dialled in case of a call – e.g. from a door station
or emergency call station.
For each call number, up to 24 digits are available.
These call numbers can be arranged in up to 8 different dialling sequences.
The dialling sequences set the order in which the call numbers will be dialled.
The dialling sequences are selected with inputs to which e.g. a time switch is connected.
Each dialling sequence is able to contain up to 15 call numbers. Thereby, each call number can be
dialled several times (by entering a call number several times in a dialling sequence).
Example
Call numbers:

Call via dialling interface: Dial the call number of the respective channel of the Gx-IAX card at the
Intercom station.
Call request/input message: For the respective channel, the “control desk function” is configured.
This means:
A call request is initiated at the Intercom station.
An input message is initiated via an input.

Take over call at telephone – call via dialling interface/call request
If a password is configured (optional), the call is accepted with this 1- to 4-digit code.
If no password is configured, the call is switched through immediately (e.g. after going “off-hook”).
Take over call at telephone – input message
If a password is configured (optional), the input message is accepted with this 1- to 4-digit code and
by pressing the button “#”.
If no password is configured, the input message is accepted by pressing the button “#” only.
End conversation
The conversation is cancelled at the telephone by pressing the button “#” or at the Intercom station by
pressing the button X.
ATTENTION: Input message
In order that input messages can be transferred to a VoIP system and that the messages can be
acknowledged accordingly, an appropriate configuration has to be carried out for these input mes-
sages. Therefore, observe notes on page 28.
NOTE: End conversation
When an outgoing conversation is cancelled, also the (call) connection between Intercom system and
VoIP system will be cancelled (contrary to incoming calls, see also “End conversation” on page 22).
