Hi IBC, bogdan,

I capture on UA 1 (caller)
1. Invite from caller send to opensips
2. opensips send to caller 100 Give a try
3. Opensips send 200 OK with SDP to Caller
4. RTP setup between Caller and RTPPRoxy
5. Caller send ACK to SIP_GW_PRIVATE_IP (that break here )

Could you please explain why ACK do not go through Opensips?
Thanks,
-LN
