Has anyone encountered this before? It's actually not for UCM, but the SIP traffic is going through ZBF on a 1941 and inbound calls are failing because the record route in the sip headers is being changed to the public interface IP of the router vs the 1 to 1 NAT IP on some responses back to the SIP Provider. I've opened a TAC case as well and it happens w/ and w/o SIP inspection.
