Re: [rtcweb] draft-kaplan-rtcweb-sip-interworking-requirements-00

Just adding one more point regarding architecture, Media plane
interworking function is an optional element for the next generation
(release) of SIP devices wherein Media agent of SIP UA will be able to
interop directly with browser media plane without intermediate
media-plane gateways.

Thanks
Partha
