<p>Sorry Daniel, hit reply by mistake!</p>

</p>
<p>So</p>
The initial invite shows;

</p>

And the ACK has the resolved From domain, as in IP address and port;<br>

<div>Although that is the case on other calls that work.</div>

</div>
<div>Shall I setup some debug on a lab instance and capture?</div>

<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><br>
</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>

<div>Many thanks in advance.</div>
