Hi Partha, just as a suggestion it would be great if you could make
correct usage of your mail client and configure it to properly
generate mail responses (by adding ">" in front of the text you are
replying) so you could stop adding <partha> to point your own text.
Writing mails in plain text (without HTML and colorized text) is also
desirable as stated in Netiquette and make easier reading your mails
to others.

Yes, but they use their own gateways and don't bothers their end users
by making Skype software to allow non secure communications. The work
is done in their gateways.

In the same way, if you want WebRTC to interoperate at media plane
with your legacy-non-secure-at-all SIP/RTP infrastructure, then build
a gateway or whatever you need. This is not the task of WebRTC nor
this WG.

You should forget about "federation in WebRTC". That's a no-go. If a
WebRTC scenario wants to interoperate with other WebRTC scenario or
with a SIP/H323/Jingle network, they both should agree on the terms of
the interoperation between their systems. The only WebRTC can state
about that is an "empty" text like "they can use SIP/XMPP or whatever
protocol/mechanism they decide in order to interoperate" which is the
very same as saying "do whatever you want".


Regards.
