Also try doing this as well in case it's still inspecting the traffic:
no ip port-map sip port udp 5060
no ip port-map sip port tcp 5060

Are you making sure the TCP connections are all torn down after disabling SIP inspection?

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.
