CUCM 8.5 integrated directly SIP Exchange 2010 sp1 UM

I have a CUCM 8.5.1 SU2 cluster with a SIP trunk ( TLS / SIP 5061) to Exchange 2010 SP1 UM. I have followed all the setup guides for the integration between the two systems. When a  call to the pilot number for exchange is made, there is no audio but I can see an RTP stream on the phone, and Exchange 2010 can see a similar session. Also from RTMT, MTP resource is being used when the call is up. As far as I can see the  call is setup correctly  and the certificates are exchanged between exchange and CUCM.

I have seen other posts where the fix is to upgrade to 8.5.1 SU2, but as I am on that one already.....any help would be greatly appreciated. thanks

Id first try and narrow down its not a TLS problem.  Can you make a test call to Exchange without TLS required?       When building systems, always setup the sytem with 5060 first, then move to 5061 TLS after.
