Hello,<br>
<br>
can you add a log message to print the source ip, call id and r-uri?<br>
<br>
It may happen that the ACK is looping back if r-uri is pointing to
itself.<br>
<br>
Also, try to get the ngrep on all devices, like:<br>
<br>
ngrep -d any -qt -W byline port 5060<br>
<br>
Pasting the ACK request here will help to see if something is wrong
with it.<br>
<br>
Cheers,<br>
Daniel<br>

However, in a pcap trace I clearly see the Route header:
<br>
This is the Record-Route in the 200 message
<br>
Record-Route:
<a class="moz-txt-link-rfc2396E" href="sip:79.170.68.157;lr;ftag=330cdf48-co1022-INS033"><sip:79.170.68.157;lr;ftag=330cdf48-co1022-INS033></a>
<br>
And this is the Route header in the ACk:
<br>
Route:

<div>I haven't been able to figure out what's going on. We have
plenty of
