Prefix
Prefix Number Definition
The following parameters (
Quick Key
[8][2][1][3][1] to [8][2][1][3][0]
) are
used for the prefix conversion, performed when dialing with the GSM module
through the voice channel only. A description of the methodology is detailed
below. For better understanding the procedure, use the examples on page
177.
Note:
The Prefix Numbers Conversion is relevant only for GSM/GPRS full version
module and is used only for voice calls.
Conversion Methodology
1. If the dialed number begins with an outgoing line number (when the
module is connected to the PBX and not directly to the PSTN line), the
outgoing line number will be deleted.
Go to step 2
2. If the dialed number begins with a prefix, (Constant prefix) recognized by
the GSM/GPRS BUS Module, the module will not change the number.
Go to step 5 else go to step 3
3. If the dialed number begins with a prefix that needs to be removed (Prefix
to remove), the module will delete the Prefix number.
Go to step 5 else go to step 4
4. If the dialed number has no prefixes known to the GSM/GPRS BUS
Module, the module will add a Prefix (Prefix to add) defined in the security
panel (usually used for the local area code of the PSTN).
Go to step 5
5. Dial
the
number.
