4. DISA

If DISA is activated and a welcome message has been recorded, this message is played

for every incoming call with the exception of calls listed in point 2 and there is a waiting

time for the DTMF number. This timeout is listed in the general parameter chart as

“Waiting time for the first number”. If the gateway receives the number of digits mentioned

in the parameter “number of direct dial digits”, it activates the connection to the PBX or

telephone connected via the port listed in the chart with the number received by DISA.

If a connection is to be made with a smaller number of digits than it is mentioned in the parameter

“Number of direct dial digits”, the selection must be finished with #. If DISA does not accept the

programmed number of digits or the # sign, the connection is not established. For this reason it is

always necessary to activate the Operator service (see below) together with the DISA function

5. Operator 1, Operator 2

The gateway supports direct dialling to two operators. So it is possible to adjust destination

number for both the GSM channels. The number of the operator is set in the general

parameter chart. E.g. the gateway may only work with the Operator service in the incoming

operation. Then, all incoming calls will be routed to the operator’s number via the ISDN

port immediately.

6. Enable CLIP from GSM to ISDN

The gateway is forwarding information about calling party number (CLIP) from GSM to

ISDN (default). Nevertheless, you can switch this function off for a particular module(s).
