Call routing - Call to GSM number goes over PRI2 interface

If the call which should be dialled to the GSM network from the gateway is forwarded to the PRI2 interface, check the Prefix lists and LCR table settings.

The prefixes for call routing to the different destinations (GSM, ISDN/VoIP) have to be set in the Prefix list (Gateway configuration - Prefixes). Then you also have to set the routing steps in the LCR table (Gateway configuration - LCR table).

If  there is no call routing record found in the LCR table, the call can also be routed to an another interface (Gateway configuration - Port modes, see picture below).
