Summary:                    [patch] REINVITE before 200ok causes a call to be
ended
Description: 
When Flash hooking:
Box 1 sends a INVITE with a contact 0.0.0.0 (Hold)
Asterisk sends a invite to box 2
Box 2 sends a trying
Asterisk sends a second invite to box 2 with a differetn CSeq, Branch and
Session version(SDP). This trigger a 500 msg.
The 500 is triggered because you cannot (according to RFC) send a second
invite when you have an unfinished dialog

Could a maintainer please delete sip_reinvite3.diff and sip_reinvite5.diff
as these are non-functioning patches.

It is worse than you think. I could probably find why the CANCEL is
repeating, but  sip_reinvite5 also prevents the reINVITE of the transferred
call legs from working properly. I'll have to re-think the patch, perhaps
preventing the redundant INVITE in the first place?
