SIP and H.323 Interworking BOF (sip323)

Monday, March 27 at 1300-1500 =============================

CHAIRS: Joon Maeng joon_maeng@vtel.com Dave Walker drwalker@ss8networks.com

DESCRIPTION:

There are two competing standards in the industry for establishing and managing real-time interactive media communications over IP. One is the proposed IETF standard, Session Initiation Protocol (RFC 2543), and the other is the ITU recommendation, H.323. Although they use the same protocol (RTP) for media streaming, they cannot establish calls between them. In the absence of any formal interoperability standards, many vendors are beginning to develop proprietary application gateways for interworking between SIP and H.323.

In order to provide interoperability between the two standards, it is urgent to define a common interworking specifications for the industry. The recognition of the need for this interworking specification has lead to calls for its development from both manufacturers and service providers, individually and through industry consortia (such as IMTC) and other bodies concerned with interoperability (such as ETSI).

In this BOF, we are going to discuss SIP and H.323 interworking issues, execution plans and the scope of the work.

AGENDA:

- Do we need SIP-H.323 interworking? - Coordination with other groups? - Scope of interworking - Outcome of the work? - Suggestions?
