Outgoing from PABX
The PBX routes the calls to mobile networks through the SS-15 BRI unit. The
SS-15 BRI may use one or two directions for this (DIR0 for module GSM0,
one mobile network, DIR1 for module GSM1, the other mobile operator)

The decision is taken depending upon the CLIP GSM table or the GSM port
settings if the incoming phone number is not found in the table.
