I think B party must terminate with 400 Invalid Request and send BYE to the existing dialog. It might be someone is snooping as well in the network.

We had an interesting question on the Asterisk developer mailing list last year. Assume that a dialog was set up in an INVITE transaction between two UAs and a proxy in between. The proxy added a record-route so the two UAs now has a route set that involves sending through the proxy. Now one UA sends a SIP request directly between the UA's instead of following the route set for the dialog. - Should this request be dropped? - Should it be accepted and processed? - Shout it be responded to with an error message - if so, which one do you suggest?
