         Proxy-Require, Supported and Unsupported header fields.

         Example: if a user agent client supports and requires the
         server to support reliability of provisional responses (IETF
         RFC 3262), this table contains a row with the option tag string
         '100rel' in jnxSipCommonOptionTag and the OCTET STRING value of
         '1010 0000' or '0xA0' in jnxSipCommonOptionTagHeaderField.

         If a server does not support the required feature (indicated in
         a Require header to a UAS, or in a Proxy-Require to a Proxy
         Server), the server returns a 420 Bad Extension listing the
         feature in an Unsupported header.
