The method includes associating a plurality of IP addresses with a single DN, communicating the association to a Switching Center responsible for routing calls between the DN and the Public Switched Telephone Network (PSTN), determining that an existing VOIP call session associated with the DN is in progress, and creating another separate simultaneous VOIP call session for the DN. A communications system includes a switching center receiving an association between a plurality of IP addresses and a single DN for providing a plurality of separate simultaneous VOIP call sessions for the DN.
