Standards bodies and industry support forums

Various industry forums have emerged to promote as well as standardize the evolving services of next generation networks. These new network services leverage a common IMS core for a horizontal signaling layer. * Alliance for Telecommunications Industry Solutions (ATIS)
IPTV Interoperability Forum
(IIF) * Multiservice Forum (MSF)
IMS/NGN Forum
* SIP Forum These forums generally host interoperability events in which multiple vendors show that services based on standards promoted by the forums can actually be deployed. They also publish specifications and interoperability agreements in parallel with standards bodies.
