      sip: negotiate both UDP and TCP for the control channel · e83a1006
      Sébastien Blin authored
      NOTE: SIP over TCP is disabled for now on Windows, waiting for
      TLS 1.3 support. To re-enable it, check the #ifdef _WIN32 in
      ice_transport.cpp
      
      Our pjsip version supports the RFC6544. With this patch, when
      starting a call, the daemon is using two ICE sessions for the SIP
      channel. One is negotiating a UDP socket, and the other a TCP socket
      and transmits both SDP on the DHT.
      
      If both negotiations succeed, TCP is prefered and will be used
      to transmit SIP messages and the VCard. This should solve the 30
      seconds timeout on bad networks.
      
      Note that the media channel is still using UDP to transmit audio
      and video.
      
      MAJOR CHANGE: the SIP channel use TLS on top of TCP, no DTLS,
      so the transport is considered as reliable.
      
      Also lot of changes in rfc6544.patch to link to rfc6062. The patch
      needs to be cleaned, cf TODO notes
      
      Also this seems to fix the ICE shutdown at the end of the call
      (after the IDLE Timeout)
