The two issues are only somewhat related. The RELEASE COMPLETE as an reply to a SETUP after having sent a CALL PROCEEDING is probably not allowed by the state transitions listen in q.931. The in-band announcement is more related to whether we have sent a progress information element which states that in-band audio is available. I think Asterisk sends such a progress message almost as soon as possible. However, in this case the problem is a CALL PROCEEDING before the RELEASE_COMPLETE answering teh SETUP. The fact that the CALL PROCEEDING also includes a PROGRESS element is incidental.
