I think INVITE with Expires 0 would be an Invalid value. I would expect that an Expires with value as 0 in INVITE request be considered as a special case and UAS should respond back immediately. Immediately would be relative depending on the time required to process the message by the UAS. But it should not return 487 Request Terminated.
