<div class="">What’s happening here is that instead of forwarding
the INVITE to the SIPp UAC, it creates a loop. Tried
KSR.setdsturi() only (KSR.pv.sets commented out) and it’s still
the same.</div>
<div class="">If I comment out the 503 reply, then that’s what the
UAC gets back.</div>
</blockquote>
<br>
<p>You have to set dst uri before KSR.tm.relay(), because that's the
function that sends to the next hop. If you set it after it, then
it is not used.</p>
