Hi Olivier,

Irrespective of TURN or ICE-TCP, SCTP over DTLS over TURN/RFC 4571 over TCP has to be supported in case SCTP datachannel mechanism has to be traversed through firewall. The similar discussion happened earlier in PNTAW and the related mail thread is http://www.ietf.org/mail-archive/web/pntaw/current/msg00144.html.

I think that it is better to discuss in detail in pntaw alias about this issue. I'll forward this mail to pntaw alias for more discussion.

Thanks
Partha
