Summary:                    The response to a CANCEL request does not always
comply with RFC3261
Description: 
The response to a CANCEL request when the original request was an INVITE
does not always comply with RFC3261.

It sometimes send a 200 OK as the answer to the INVITE instead of
responding with a 487 to the INVITE request.

Quote from paragraph 9.2: "If the original request was an INVITE, the UAS
   SHOULD immediately respond to the INVITE with a 487"

this bug is timing/load dependend
