inaki,

based on what in rfc3261 syntax?

Contact        = ("Contact" / "m" ) HCOLON
                 ( STAR / (contact-param *(COMMA contact-param)))
contact-param  = (name-addr / addr-spec) *(SEMI contact-params)
name-addr      = [ display-name ] LAQUOT addr-spec RAQUOT
addr-spec      = SIP-URI / SIPS-URI / absoluteURI
display-name   = *(token LWS)/ quoted-string
contact-params = c-p-q / c-p-expires
                 / contact-extension

SIP-URI = "sip:" [ userinfo ] hostport
          uri-parameters [ headers ]
		 
my reading of the above is that the whole contact body can be an
addr-spec.
