Fax recognition and DDI module

Incoming fax calls are recognised and/or DTMF suffix dialling interpreted with the fax/DDI op-
tion. The following functions are possible:
Fax recognition
This function supports automatic switching to a defined extension when receiving a fax or mo-
dem call. When this function is activated, a trunk call is answered immediately. If a fax control
tone is present, the fax connection is automatically through-connected. If no fax tone is present,
the trunk call is switched to the extension predefined in the system (intercept console). After
the call is answered, a recorded announcement informs the caller of the fax check.
DDI
This function permits a desired extension to be accessed directly. When this function is en-
abled, a trunk call is answered immediately. A recorded announcement informs the calling party
that he or she can reach an extension directly by means of DTMF suffix dialling. If no suffix di-
alling occurs within a certain period of time, the trunk call is switched to the extension pre-
defined in the system (intercept console).
Fax/DDI
When the appropriate system configuration (programming) is set, the fax and DTMF suffix di-
alling features can be implemented in combination using an options module.
Automatic fax recognition (AutoFax)
Lines that are not assigned to a fax option are also monitored for fax signals.
If an extension recognises a fax activation tone after answering an external call (within 10 s),
the connection is automatically routed to the fax machine and the call to the internal extension
is automatically disconnected.
Terminal display: "Fax being received, please hang up"
Recorded announcement before answer
Only the fax/DDI module's recorded announcement feature is used for this. The announcement
module can be entered as a pseudo port in Call Management. If this entry is active (e.g. as the
first port called), the announcement is played for the caller. The system then switches directly
to the next extension/group entered.
As of SW 2.1, the extension number of the destination to which the option is to forward a call
must be entered directly after option type "873" (announcement) in Call Management.The call-
er will incur call charges from the start of the announcement.
