That's true. However it's also true that regardless of the fact that lots
of people want to contribute to it, SG16 has not officially sanctioned
this work, and neither has the IETF. So I humbly suggest that these
discussions be confined to the neutral mailing list that was started
expressly for the purpose of discussing SIP-H.323 interworking:

Hi everyone,
If I am not wrong, the discussions and the benefits of IMTC groups are more
or less restricted to IMTC members.
And to become a IMTC member, it costs $7500 anually which will restrict the
open contribution from small companies
and enthusiastic fellows.
As mentioned by Radhika, the purpose is to come out with a proposal which
is widely accepted and commented by a large
community. So , I would rather prefer SG16 to be a better place of
discussion.
I would like to have the views of other members also from this group.
Best Regards
Vipin Palawat
