Abstract
A system that incorporates teachings of the present disclosure may include, for example, receiving a request for a voice call at an interrogating call session control function server of an internet protocol multimedia subsystem where the call is associated with an originating communication device, transmitting a mapping query from the interrogating call session control function server to a database to obtain an internet protocol address for establishing the call with a recipient communication device in response to the request for the call, and routing the request to a server of the internet protocol multimedia subsystem or a second server based on a response to the mapping query provided by the database. Other embodiments are disclosed.
