Example:
- <empty> ...roaming restricted
- 2300
...roaming restricted (minimum is five digits)
- 23002 ...roaming enabled only to network code 23002
- 230Xx ...roaming enabled to network codes from 23000 to 23099
- xX001 ...roaming enabled with codes which has last three digits = 001
- xXXxX ...roaming enabled to ANY GSM/3G network code
CLIR – This parameter decides whether the gateway SIM card subscriber number shall be
dialed into the GSM network or not. All PRIGW outgoing calls present the calling line numbers
as inserted in the SIM card in the PRIGW. Technically, it is impossible to transfer number
information from the ISDN into the GSM network (the opposite function is supported, i.e. all
ISDN subscribers can see the GSM calling number). Hence, it is mostly purposeful to restrict
the calling line identification (activate CLIR) to avoid problems with back calls to the gateway in
the case of a missed GSM call, for example. Select this parameter for each GSM group
separately.
− Default - settings according your GSM provider’s network.
− Enabled (CLIP-off)** – The CLIR function is activated, no numbers are sent to the
GSM network. CAUTION! Your GSM provider must support and activate this service!
If not, the number will still be sent to the network and outgoing calls will be impossible
with some providers.
− Disabled (CLIP-on) - the CLIR function is disabled, numbers are sent. Your GSM
provider must support and activate this service! If not, the number will still be sent to
the network and outgoing calls will be impossible with some providers.
**Some GSM network (SIM cards) not support activation CLIR via GM22 GSM modules, in
status window you will see Network: clir-err.
Number of called minutes – Time call limit for one month for the SIM card.
Number of SMS messages – Number of SMS messages sent via the SIM card / one month.
Day of restore limits – Day, when counters “time call limit” and “SMS” will be reset to zero (1 to
31, 32 = limits will be restored every midnight).
First count – length of first count. After this timeout PRIGW uses parameter “next count” to
calculate the length of the call. (1 to 250 seconds).
Next count – length of next counts (1 to 250 seconds) . Next count – length of next counts (1
to 250 seconds) .
Parameters First count and Next count are used for calculating of the real length of the call from the view of
GSM operator.
Example 1: If your calls are charged second by second set both parameters to 1.
Example 2: If you are charged immediately after answering a call for the whole first minute and then second
by second set first count to 60 and next count to 1.
Proper setting of these parameters helps you to keep real record of the minutes spent and charged for
each SIM. These parameters are used for limit counters, statistics (not for the CDR).
Time of use SIM – Interval of using selected SIM card. Caution!: If parameter “Time of use will
be overlapped by another SIM (in one GSM group) – in this case can come about unspecified
switching of SIM cards – can be selected another SIM cards !
