I think I have multiple issues going on but I might be getting closer to the issue.
<br />
<br />I am wondering if this might be part of the issue.
<br />
<br />If you look at the the following, http://www.tech-invite.com/Ti-sip-dialog.html#inv , for the first INVITE message that the Callee receives the first Proxy that the callee needs to take in its Record-Route is first in the list of Record-Routes on the INVITE message. As for the Caller the Record-Route set gets flipped (whatever Record-Route is on the top will be its last route hop). So if this is the case then why is the OpenSIPS/SBC device sending my Callee device an INVITE message with the far end proxy, OpenSIPS/Proxy, on the top of the Record-Route list? Here is the INVITE that my callee is getting
<br />
<br />INVITE sip:9013XX3XX6@192.168.88.14:3072;line=9zx0whnm SIP/2.0
<br />Record-Route: <sip:50.XX.XX.156;lr;ftag=4aoni525hc;nat=yes;vst=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA;did=598.b8b26331>
<br />Record-Route: <sip:99.XX.XX.161;r2=on;lr>
<br />Record-Route: <sip:192.168.88.1;r2=on;lr>
<br />
<br />
<br />The Record-Route with 50.XX.XX.156 should be at the bottom of the list I think because that is the OpenSIPS/Proxy that is on the Internet. Am I wrong on this? On the SIP trace I posted on pastebin this INVITE to the Callee starts on line 299.

In wireshark it's a lot easier to jump from a message to another through the call flow. You can use tcpdump to capture to .cap file for wireshark.
