Hi<br><br>After re-subscribing to a user presence, we receive immediately a NOTIFY with no content:<br><br><div style="margin-left: 40px;">NOTIFY sip:user1@XX.XX.XX.XX:5060 SIP/2.0<br>Via: SIP/2.0/UDP YY.YY.YY.YY:6667;branch=z9hG4bK34ab.7700bc14.0<br>

CSeq: 5 NOTIFY<br>Call-ID: 87cbad243e9c1b48c8333cbbb99cb282@XX.XX.XX.XX<br>Route: <sip:YY.YY.YY.YY:6666;lr=on><br>Content-Length: 0<br>User-Agent: OpenSIPS (1.5.2-notls (x86_64/linux))<br>Max-Forwards: 70<br>Event: presence<br>
Contact: <sip:sa@YY.YY.YY.YY:6667><br>Subscription-State: active;expires=100<br></div><br> and then few seconds later I receive a NOTIFY with the proper presence document.<br><br>Which are the possible reasons why the presence server sends an "empty" NOTIFY ?<br>
<br>Cheers<br>Pascal<br>
