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.
