I believe my fix in the comments of ASTERISK-19303 may address this issue also.  Might need the same fix in a different location though.

The general issue seems to be that in many of the handle_request_invite error scenarios, it doesn't copy req to initreq and doesn't set pendinginvite, which on handle_incoming SIP_ACK makes SIP pedantic unhappy thinking the ACK isn't associated with an existing dialog, and even with pedantic off the lack of pendinginvite causes handle_incoming to discard the ACK rather than calling __sip_ack.

The last of these fixes should be in the 1.8 branch and in  Please test with a version that is at least and let us know if this is still a problem.  If it is, then a bug marshal can be contacted in #asterisk-bugs or on the asterisk-bugs mailing list.  Thanks!
