Strictly, for an error like that, there should be a "404 Bad Request"
response
but you might decide it is better to treat it as if it is missing:

   If the Content-Disposition header field is missing, bodies of
   Content-Type application/sdp imply the disposition "session", while
   other content types imply "render".

In this case, I think I would opt for a 404 response and then
inform the UA vendors that their UA is misbehaving.

I agree with Attila, although beware he typed "404" where he should have typed 
"400".  (404 is "Not Found".)

Be careful that your parser will accept all possible future extensions of 
Content-Disposition as specified in RFC 3261 section 25.1 -- you wouldn't want 
your device rejecting calls that implemented some future extension.
