<p>If I am reading well RFC 4662 Section 4.5 (<a href="https://tools.ietf.org/html/rfc4662#section-4.5">https://tools.ietf.org/html/rfc4662#section-4.5</a>) Kamailio should send a full state NOTIFY for initial RLS subscribes and then it can send a partial state for updates.</p>
<p>I think we lose information here, but if a re-subscribe is performed I get a full NOTIFY, which is my current "workaround" :</p>
<p>1 - Initial subscribe<br>
2 - If full state -> OK<br>
3 - If partial state -> re-subscribe</p>
