After simulation, the normalised calling and called numbers plus the name of the
successfully found output line or the reason why the line search was unsuccessful are
displayed.
GSM Routing
Incoming calls from the GSM network are processed by simply being routed to a
selected number in the VoIP network. The routing rule may be set for each SIM card of
the GSM module separately.
While processing GSM incoming calls, the LCR first tries to find the Operator service
according to the GSM module and then according to the SIM card number. After finding
the service, it selects the line that is assigned to the Operator service for the incoming
call. Finally, the calling number is normalised according to the normalising table.
Operator
To set routing click on the GSM routing reference. The Operator service must be set
first. Click on the Operator item to display the table of available operators (see Fig.
3.64).
