Hi Daniel,
I know, shocking (heh)!
The protocol violations were very slight - omitting SDP rtpmap lines for dynamic RTP payloads, omitting a=rtcp-mux for RTP+RTCP mux (but they're already muxing SIP too, so ehh). Possibly others.

Hello,
interesting, thanks for sharing!
What else I could say, I am really deeply extremely ... (can't find other words) ... shocked they don't use SIGCOMP specs [ha ha!]! I remember some discussions when I said that usage of one well established compression algoritm will get it done in few hours (implementatio wise) than what IETF came up with in this regard. Sad but true, many IETF specs have no touch with reality...
Maybe I missed while quick reading, what are the "various /slight/ protocol violations" you spotted?
Cheers, Daniel

I've been spending some time looking at some of the significant changes Apple has made to Facetime in iOS 7. I'm far from an Apple fanboy but some of them are pretty interesting:
- multiplexing everything over a single UDP port
- deflate compression with SIP
- various /slight/ protocol violations ;)

As SDP bodies swell more and more can we hope to build significant support for multiplexing and deflate compression in the SIP-focused open source ecosystem?
