[cisco-voip] CUCM 10.5 and OpenText 10.6

[Countryman, Edward]

We have had right fax 10.5 up and running with a SIP trunk from our CUCM 8.6.2 environment for a while now.

This past weekend we updated to CUCM 10.5.2 and are no longer able to fax out from RF.

From the trace, the SIP call appears to fail with the following error after the INVITE

488 Not Acceptable Here

Do would anything have changed in 10.5 to possibly be causing this?   Weird thing is the inbound faxes are working fine.
