3. User Manual – Description of Basic (Voice) Function
Users mostly use their PBXs and GSM Gateways intuitively, without reading any
instructions, or follow very simple instructions provided by an authorized person. The following
functional description is therefore intended for technicians, who follow the instructions
(depending on the PBX set-up) and solve any operational problems.
3.1. Outgoing Call to GSM
3.1.1. Picking Up the Line
The PBX picks up a line the moment a subscriber picks up his or her handset and dials a
number (or prefix) that is routed outside.
Note: If the GSM Gateway is busy, the PBX can either give the caller the busy tone
or choose another connection (PSTN, or there may be more GSM
Gateways with one PBX).
