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?

  • Hi Kristian,

    Thanks for sharing your analysis. Interesting read. Makes me wonder why not more vendors/projects are doing port multiplexing. Let’s hope it will pick up steam now that Apple has implemented it.
