[Spce-user] Problem with sipwise and snom m9

Hi,

i took a short look at sipwise 3.0 using a snom m9 phone amongst
others and went into some trouble. Everything seems to work fine, but
if i call the m9 and hangup before accepting the call the m9 rings
further until its own timeout. Following the communication between
sipwise and the phone there seems to be a problem with the CANCEL
message, where the phone reacts with a 400 reply. I have the part of
the tcpdump attached. I'm not quite sure, if it's a phone firmwarebug
or something with sipwise, in a former and retired asterisk
installation the phone didn't have the problems *g.

	Regards
		Bernhard Dick
