How are calls routed from landline telephones to the GSM network?
The Nokia 22 can be connected to an analog trunk or extension line of a PBX. The PBX, in turn, can be programmed to automatically route the calls made from a landline telephone to a mobile number via the Nokia 22. When the Nokia 22 operates in the extension mode and the PBX is not programmed to automatically route calls, calls can be made directly to the extension number where the Nokia 22 is connected.
