We are using OpenAI Realtime SIP/RTP for a telephony voice bot.

During an active SIP call, our RTP sender may change SSRC due to failover, endpoint restart, hold/resume, or media path change.

Please confirm the expected OpenAI behavior for:

  1. SSRC change during silence
  2. SSRC change during active speech
  3. SSRC change with RTP sequence/timestamp reset
  4. SSRC change with source UDP port change
  5. SSRC change after re-INVITE/hold-resume
  6. Whether the same Realtime call_id/session is preserved
  7. Whether there are limits or throttling for multiple SSRC changes
  8. Whether RTCP BYE is expected for the old SSRC
