[OpenSIPS-Users] Problem with Opensips routing Reinvite ACK

Hi, we have a set up as follows using Opensips 1.6.2

UA  ->   OpenSIPS  -> SIP Provider

TLS        TLS           UDP
           UDP

We can set up a call from Sip Provider to UA. However when we issue a Reinvite due to (Hold) from UA the Sip provider gets the invite and sends 200K to which the UA responds with an ACK , however Opensips does not seem
to be routing this ACK back to the provider. Strangely the Reinvite which initally started this has the same route set, yet that reaches the provider.

ACK sip:anonymous at 217.10.79.23:5060 SIP/2.0
