Ticket #602:

  • Introduced new API pjmedia_rtp_session_init2() to enable intializing RTP session with non-default initial settings
  • Updated stream so it can be created with non-default initial RTP settings.
  • Updated pjsua-lib to make sure RTP timestamp and sequence contigue when stream session is restarted.
