Section 4.2 of draft-ietf-sipcore-location-conveyance-03 says:

    A SIP intermediary can also reject a location it receives from a
    Target when it understands the Target to be in a different location.
    The proper handling of this scenario is for the SIP intermediary to
    include the proper location in the 424 Response.  This SHOULD be
    included in the response as a MIME message body (i.e., a location
    value), rather than as a URI; however, in cases where the
    intermediary is willing to share location with recipients but not
    with a user agent, a reference might be necessary.

Does this leave the Target's ability to spoof its location up to the  
discretion of the SIP intermediary?

Thanks,
Alissa
