In this scenario a 200ok is sent to the caller, but no ACK is sent back. This appears to return true for timeout checks. I will grab a SIP trace. As a side note / update I figure I can potentially add a flag / AVP when a response and / or ACK is received and figure out the cause of the timeout from there. Thanks for your assistance.
