<div dir="ltr"><div>Hi,</div>
<div> </div>
<div>Kamailio server is behind our company's softswitch and acts as a sip application server.</div>
<div>I notice that there are calls that the softswitch replied with 503 "service unavailable" and kamailio sent to the originator leg 500 "service unavaileable".</div>
<div>When kamailio recieved 504 or 502 it sends them back as is. shouldn't it be the same with 503?</div>
<div> </div>
<div>It also does not have a "to tag" in the CDR. And the "to tag" in the 503 that was recieved is not equal to the 500 reply "to tag" kamailio sent back.</div>
<div> </div>
<div>any ideas?</div>
<div> </div>
<div>BR,</div>
<div>Uri</div></div>
