FYI - SIP-H.323 Interworking BOF

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
