It seems that for some reason openser(555.111.555.111:5060) will not forward the ACK packet in this scenario. Config at bottom. ACKs from other clients seem to get forwarded just fine. Have tried both 1.0.1 and CVS-head same results..
Thanks

ACK is in SIP Message 9 which openser should then send to 77.159.77.105:9193
