7.2.1 SIM Blocking
The VoIP2ALL has SIM blocking mechanism to decrease the unsuccessful calls from a SIM that
making unsuccessful calls or seems to be blocked by the network.
There are three reasons that the gateway will block a SIM:
1. The SIM was blocked manually by the 'Block' button in the 'Block Options' area.
2. The SIM has made consecutive unsuccessful calls in the amount of 'Blocked Threshold'
(see the 'General' tab in 'Ports' window).
3. The SIM has made consecutive "message announcement" detected calls in the amount
of 'Number of Detection' (see the 'General' tab in 'Ports' window).
4. The SIM has tried to register unsuccessfully and reached the 'SIM Registration Time
Limit'.
When the SIM is blocked, it will be unregistered from the port and will not be able to work on
any other port until you manually unblock the SIM.
Blocked Cause
The 'Blocked Cause' will show the status of the blocking. The code options are:
0 – The SIM is not blocked.
1 – The SIM is blocked by reason 1.
2 – The SIM is blocked by reason 2.
3 – The SIM is blocked by reason 1 and reason 2.
4 – The SIM is blocked by reason 3.
5 – The SIM is blocked by reason 1 and reason 3.
6 – The SIM is blocked by reason 2 and reason 3.
7 – The SIM is blocked by reason 1 and reason 2 and reason 3.
8 – The SIM is blocked by reason 4.
Unblocking a SIM
To unblock a SIM simply press the 'Clear' button and the 'Unblock' button and then save the SIM
server settings. The unblocking will take effect immediately.
Manually blocking a SIM
To block a SIM manually simply press the 'Block' button and then save the SIM server settings.
The SIM will be blocked when it will finish working (either at the end of defined time in the time
table or when you reset the port).
There is an option to set the gateway to block the SIM after the next call (please contact the
support for this option).
Chapter 7.3: Profiles
The Profile is the collected parameters that a SIM will use when activated. You can define up to
10 different profiles. Each SIM will use one of the predefined profiles.
The profile allows you to easily set the same parameters to a group of SIMs.
