Charter for Working Group

There are two competing standards in the industry for establishing and
managing real-time interactive media communications over IP. One is
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
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.
