1General functions
1.1 Fax via GSM
It is possible to send and receive faxes over the GSM mobile phone network using a custom
G3-fax machine. You can use the WLL550 Pro gateway with integrated FXO or any
AS55x/WLL550 VoIP gateway with an analog telephone adapter via a dedicated SIP-channel.
Normally fax transmissions over the GSM network are critical because the handshake is not
optimized fir it. For better results the WLL550 Pro buffers the transmission process and splits
it into two phases. First the fax document will be submitted from the sending machine to the
WLL550 Pro's memory and then time-delayed from the WLL550 Pro memory to the receiving
fax station. The WLL550 Pro will try up to three attempts to submit a fax. During this time
the channel LED is flashing continuously and no further call is possible via this channel.
However a fax transmission can fail for some reason and by splitting the transmission it
might happen that the first phase of the transmission is successful but the second phase
fails. To ensure that the sender gets information about the unsuccessful transmission the
WLL550 Pro can generate a receipt for all successful and failed fax transmissions via a
response fax.
For using the fax service a SIM card with activated GSM-fax service is mandatory. Ususally
you will get a separate fax number from your service provider (also called multi-numbering).
All incoming fax calls will be forwarded automatically to the analogue fax port or the SIP fax-
channel. Outgoing faxes will be forwarded via a GSM-channel (UMTS and LTE do not support
the GSM fax service).
For programming instructions see 5.5.
1.2 Callback
Due to the restrictions of displaying the CLIP within GSM networks ( ‘CLIP -no screening’ is
not available and only a GSM number can be transmitted) a called party does not know
which PBX subscriber is calling via the AS55X or who has initiate the call-setup. The called
subscriber however, cannot reach the call initiator for a call back, because all subscribers of
the PBX could have initiated this call. For this purpose the AS55X can record calls or call
setup data.
All call-setups could be saved, so the AS55X can backtrack every call setup’s origin. The
called party initiates a call to the transmitted CLIP number (one GSM number of the AS55X)
and by using of the call-setup list the callback can be routed the original subscriber of the
PABX. Please consider that only the last call to one destination can be saved. A previous
existing call-setup will always be overwritten by the new one. It is mandatory that both sides
transmit their number (CLIP).
For programming instructions see 5.8.2, 5.8.3, 5.10.2 and 7.5.

1.3 Callback termination
The callback termination function is implemented to save fees on the mobile phone site. It is
possible to call the AS55X with or without transmitting your caller ID (CLIP / CLIR). The call-
setup or the call will be aborted immediately and the AS55X will initiate a callback to the
mobile phone.
There a few different possibilities:
1st: the incoming call will be rejected by the AS55X
(free of charge, callback via CLIP)
2nd: the incoming call has to be rejected manually by the mobile phone
(free of charge, callback via CLIP)
3rd: the call will be rejected after entering a code
(NOT free of charge, callback via DTMF code)
For programming instructions see 5.10.1, 5.8.2 and 5.10.3.
1.4 Short message callback request
To improve the callback options the ‘short message callback request’function is
implemented to supply a called subscriber with additional call information. If you call a
customer via GSM you can choose between number presentation (CLIP) or number
restriction (CLIR). In case of CLIR is active the customer sees a number of the AS55X but
could not know who is the subscriber of the calling number. With ‘short message callback
request’it is possible to send a SMS short message after a call with additional call
information. Two different text templates with up to 160 characters can be defined. The
selection of the text to be sent depends on the calls origin is within the PBX domain or not.
The text phrases are always the same but can be complemented by the following variables:
Calling number (SIP or ISDN number of calling party)
GSM channel number as displayed
GSM channel number in national order
Freely entered number via DTMF.
It is possible to send this short message automatically or controlled by the customer via
DTMF code. The calling party name is available for the SMS callback request for SIP calls.
For programming instructions see 5.8.5
