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

By the way, this is more general that I first anticipated. 

Asterisk doesn't seem to be aware if there is a transaction going on with
a UA at all time.

Specificaly, the exact same behavior for the reinvite happens for BYE as
well (BYEs are transactions too). A BYE can be sent to a UA before the 200
OK to an INVITE. And this doesn't seem to be corrected by the patch of
One47 (thank you for the patch btw). On BYEs, this is not noticeable right
away, but after a transfer, I see trailing 200 OK from my Mediatrix units
because of this.

Maybe One47 would also want to take a look at this ?

Thanks
