Summary:                    race condition in sip hangup with reinvited media
Description: 
Condition: Server A (Asterisk 1.4.1) places call on server B (1.4.1) which
extends it to the provider, C (sonus)

When Asterisk 1.4.1 reinvites, and then the call ends, it reinvites the
destination end back to itself, then sends a bye without waiting for the
re-invite to be complete, causing a race condition.

If we are going to re-invite (back to ourselves), we should wait for the
100 Trying, then 200 OK, then ack the 200 OK, and only then, send a bye.

Initial tests seem to indicate that the sip_reinvite6.diff patch in
http://bugs.digium.com/view.php?id=9305 resolves this issue.  Hopefully we
can get some further testing and get it in to 1.4/trunk ASAP.
