Abstract: Aspects of the subject disclosure may include, for example, determining from a transport protocol message, capability information associated with user equipment associated with a call session, determining a first codec to provide a first media service to the user equipment associated with the call session according to the capability information, and responsive to determining the first codec, searching a codec table to obtain a first resource identifier associated with a first media resource function to provide the first media service according to the first codec. If the first resource identifier associated with the first codec is not available at the codec table, accessing the first resource identifier associated with the first media resource function from a domain name server and, in turn, transmitting a first request to the first media resource function to provide the first media service to the user equipment associated with the call session. Other embodiments are disclosed.

Abstract: A method, apparatus and computer-readable medium for identifying a subscriber home domain in a communication network are described. A national subscriber profile is partitioned into regions and a NAPTR resource record is modified to identify in which region a particular subscriber is located. In response to a calling party requesting that a connection to a called party be established, a database is queried to provide a modified NAPTR record which identifies the region in which the called party is located. A connection can then be established without polling each region.

Abstract: A method and an apparatus for completing a circuit switched service call in an Internet Protocol network are disclosed. For example, the method receives a session request and queries an tElephone NUmbering Mapping server for a called party, and determines if at least one Naming Authority Pointer resource record associated with the called party is received from the ENUM server. The method determines if a Session Initiation Protocol Universal Resource Identifier is returned, if the at least one NAPTR resource record associated with the called party is received, and processing the session request using the SIP URI, if the SIP URI is returned. The method determines if the processing of the session request using the SIP URI resulted in a successful call completion and processes the session request using a telephone URI, if the processing of the session request using the SIP URI resulted in an unsuccessful call completion.
