Hello Jeff,<br>
<br>
Your OpenSIPS probably routes that ACK as a strict router, since it
sees that in the R-URI there's an IP where it's listening on (
opensips_WAN_public ).<br>
The contact in the 200OK had <a class="moz-txt-link-abbreviated" href="mailto:sip:9998887777@172.21.201.1:5066">sip:9998887777@172.21.201.1:5066</a> , so
this should have been in the ACK's R-URI. Try to fix the softswitch.<br>
<br>

<div>You can see the ACK come in from the softswitch to Opensips's
public interface starting at line 212. I'd expect this to relay
through to the private side, but instead, we see starting on
line 228 it relays the ACK to itself on its private interface.
I don't know why that is happening.</div>

Can you post the pcap captures somewhere so I can take a look?<br>
