<p>Hello,</p>
<p><br>
</p>
<p>the second packet in the trace has \0 in the To header. Likely
the endpoints is changing the From/To headers and restoring them
with uac module is no longer working. Either don't auto-restore
them or use uac with dialog module to store the the values.<br>
</p>
<br>
Kamailio 4.4 or newer should have a better detection of this case.<br>
<br>
Cheers,<br>
