Unique. I assume that you are not attempting to use rfc6140 or rfc5626. > How could the SIP Server or Registrar verify that these > two numbers are in fact originating from the same Device? As far as I know, that is outside of the scope of rfc3261 unless you want to make assumptions/deductions concerning some header values (such as Contact or User-Agent). RFC 6140 may be of interest. _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is essentially closed and only used for finishing old business.
