<p>Hello,</p>
<p>do you have the INVITE and the 200ok corresponding to this ACK? I
need to see the R-URI of INVITE as well as the contact in 200ok in
order to analyze why sips appears in ACK.<br>
</p>
<p>SIPS requirements are sort of a mess, probably the best would be
to let it for config to decide when to allow forwarding or not in
case of sips URI.</p>
<p>Cheers,<br>
Daniel<br>

<div>We're having an issue with Kamailio not processing an ACK
and hope someone can help. A PCAP shows that Kamailio is
receiving the ACK, and we believe these log messages are
directly related to it:</div>

<div>The ACK is as follows. It's from telephone 111111 which
is using TLS, which Kamailio listens for on port 5061.</div>
<div>Does anyone know which URI has the bad transport as per
the error above? Might it be the From URI "<a
href="mailto:sips%3A111111@es8.example.com"
moz-do-not-send="true">sips:111111@es8.example.com</a>"
because it doesn't specify port 5061?</div>
<div>Thank you in advance.<br>
