Hi, Everyone:
ITU-T and IETF are the formal standard bodies to create standards for H.323
and SIP, respectively, and the interworking standard between the two is also
a part of it..
However, all inputs from other organizations will definitely be welcomed.
Best regards,
Radhika R. Roy

> In order to provide interoperability between the two standards, it

> urgent to define a common interworking specifications for the

> The recognition of the need for this interworking specification

> In this BOF, we are going to discuss SIP and H.323 interworking
