<p class="MsoNormal"><span style="color:#1F497D">The multiple records are because we are routing calls between UAs which are both registered against Kamailio via an external SIP server (our billing engine). That is causing there to be 2 dialogs created.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
when you get such situation, can you check the database and see if there are more records for the same presence dialog?<br>
<br>
Also, can you send here the parameters for pua*/presence* modules? DB URL parameters are not relevant, you can skip/replace them as they contain password.<br>
<br>
Cheers,<br>
