Also, a network element which comprises the database as well as a control entity, the control entity being operative for receiving an incoming call originated by one of the communication devices, determining the directory number associated with the communication device having originated the call, determining whether the call is an emergency call and, responsive to the call being an emergency call, accessing the database to obtain the routing information related to the directory number and directing the call as well as the routing information over a trunk group dedicated to emergency calls.
