5.6. Incoming calls from GSM and ISDN
Below, you will find points that an incoming call goes through. These points are listed in
their real order. All these services can be authorised or prohibited selectively.
1. CALLBACK
When the function CALLBACK is activated and an incomming call has the same CLIP as
CLIP for CALLBACK, the GSM gateway for defined time doesn’t receive this incomming
call (the call is only ringing). In case that the calling party is still calling (after timeout), the
GSM gateway connects this call according to below listed points. In case the calling party
terminates the call before timeout, the GSM gateway activates the function CALLBACK: It
starts calling to a defined extension. When the extension hangs-up the call, the gateway
starts calling to GSM (called party number = CLIP of incoming call). During building of this
outgoing call, the gateway plays to an extension a defined voice message. When the
called party hangs-up the call, the gateway connects this call to the extension
2. Prohibited numbers (restricted CLIP)
If the gateway finds an agreement between a received number from a GSM network and a
number listed in the chart of prohibited numbers, the call is rejected correctly. The phone
with this number has no possibility to call the gateway.
3. Clip Routing
If the gateway finds an agreement between the incoming number and a number listed in
the CLIP routing chart, it activates the connection to the PBX or telephones connected via
the port listed in the same chart with the “direct dial number” from the chart. The CLIP
chart can be modified by the ISDN GSM program. You can also add items using your
ISDN telephone.
4. Auto CLIP routing
When this function is activated, the gateway begins to register information about outgoing
unconnected (connected) calls in to its local RAM memory. The following information is
saved in to the memory:
- The called number
-
The calling number
- Date and time of the call
In the case that a number that had been previously dialed and registered in to the memory
calls back to the gateway within a configurable period of time, this call is routed to the
subscriber who last dialed the particular number.
