Summary:                    [patch] Asterisk sends wrong CSEQ in CANCEL if using
INFO dtmf
Description: 
SIP RFC states that a CANCEL to an INVITE must have the same CSEQ as the
INVITE. When asterisk sends INFO packets, it increments the ocseq counter.
When it sends the CANCEL, the cseq is not that of the INVITE but of the
last INFO.

(Please don't ask me for logs... they're not going to say anything more
than what I just said above. )

This is a big problem as the other party thinks the call is still going
(it rejects the improper CANCEL).
