Abstract
A telephone handset is provided with a user interface which includes a display unit, audio output unit and various user actuable keys. A phone controller implements and responds to instructions from the user interface. Where the instructions from the user interface request the connection of a call, the phone controller connects the handset to a PSTN via one of a plurality of connection means provided. Similarly, in the event of an incoming call connection request received via any one of the connection means, the phone controller enables the connection of the call. The user may choose to accept or reject the connection using the interface. The handling of an incoming or outgoing call is determined by a connection routing engine. The connection routing engine comprises an identification unit, a rules unit, a comparison unit and an enabling unit.
