<div dir="ltr">AFAIK the only way to "match" reg and invite (by sip design) is to use separate auth data for each reg. Client could use random port for UAC's and e.g. 5060 for UAS, so you can't really rely on contact vs src host:port matching.<br></div><div class="gmail_extra"><br><div class="gmail_quote">2014-11-28 22:07 GMT+03:00 Luis Azedo <span dir="ltr"><<a href="mailto:luis@2600hz.com" target="_blank">luis@2600hz.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>the problem i see is that the INVITE Contact doesn't match the one registered.</div>
<div><br>
</div>
<div>is this a problem with sip.js or am i missing something in kamailio.cfg or should kamailio save the contact info as sip.js is sending?</div>
<div><br>
</div>
<div>Thank you</div>
