Abstract
A system that incorporates teachings of the present disclosure may include, for example, receiving a request for a voice call at a mobile switching center server, transmitting a mapping query from the mobile switching center server to a database in response to the request for the voice call, route the request from the mobile switching center server to an internet protocol multimedia subsystem for facilitating establishing the voice call when the mapping query is successful in obtaining an internet protocol address for establishing the voice call with a recipient communication device, and routing the request from the mobile switching center server to a second server for facilitating establishing the voice call without routing the request to the internet protocol multimedia subsystem when the mapping query is not successful in obtaining the internet protocol address. Other embodiments are disclosed.
