Fwd: [OpenSER-Users] Transaction Deletion

Hi Brandon,
But according to the trace, the ACK is correctly routed further by your
OpenSER (to .202)....Most probably the end device from the other end
does not receive the ACK and keep resending the 200 OK.
So, you end up with this retransmission of 200OK + ACK ......and at a
point, openser drops the INVITE transaction and the ACK will not be
matched anymore, but this should not be a issue as the ACK for 200 OK
are separate transactions and routed only based on RR+contact.
regards,
bogdan
