The invention relates to a method of routing a call made to a fixed telephone number of a UMA-subscriber in a mobile telecommunications network comprising a first and a second switching node and a location server. Location information of said UMA-subscriber is acquired wherein said location information comprises a location area code or a combination of location area code and cell identifier associated with a serving BSC or a serving GANC. The call is connected to the UMA-subscriber when the location area code or combination of location area code and cell identifier is associated with one of a group of GANCs, or connected to an alternative destination, such as a voicemail service, if the location area code or combination of location area code and cell identifier is not associated with said one of a group of GANCs. The methods described in the present invention disclosure allow for very efficient offering of UMA in combination with geographic numbers.
