<div>Hi Guys,</div>
<div><br>
</div>
<div>running kamailio 4.1.4 and using uac_replace_from, I am
seeing a strange issue with the proxying of an ACK message
back from a carrier to freeswitch on the ingress path into a
network.</div>
<div><br>
</div>
<div>So its just a normal call inbound, where on outbound leg we
modify the From address, on the inbound leg all remains the
same.</div>
<div><br>
</div>
<div>Now after the ingress side receives the 200ok, it sends an
ACK as below;</div>

<div>Causing FreeSWITCH to not recognise the request, and
therefore not send an ACK.</div>
<div><br>
</div>
<div>There are no rules set against the ACK processing.</div>

</div>
<div>Has anyone seen this before? We dont know when it started
happening which doesnt help, I will look to setup debug on
test environment but just wondered if this is an issue thats
been seen before?</div>
