I'm in need of some helpful pointers, and if possible, details with the following scenario:</div>

First, my use case; we host multiple customer FreePBX instances across our cloud system. Currently our customers access their PBX via VPN. Recently we've had requests that would require us to provide more direct access to the PBX from the Internet and using
a VPN is not an option. This includes devices that don't support VPN, softphone's on systems that can't have a VPN client installed on them, etc.</div>

To solve this, I believe the correct solution is to provide a SIP proxy on the edge of our network with the following capabilities:</div>

<div><span class="ContentPasted0">I followed the tutorial located here (<a href="https://fatiherikci.com/en/opensips-installation/" id="LPlnkOWALinkPreview">https://fatiherikci.com/en/opensips-installation/</a>) and, with a few other resources, managed to get
an instance of <span style="display: inline !important; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);">
openSIPS</span> with the control panel running. However, I'm now at a loss for how to write a script that acts as a pass-thru proxy. By pass-thru, I mean all messages including auth/registration going through to the backend PBX.</span></div>
<div><span class="ContentPasted0"><br>
</span></div>
<div><span class="ContentPasted0">For some further context, I've also installed DSIProuter (Kamailio/RTPengine/Web UI) that has the ability to "pass-thru" request to an endpoint based on the domain. It partially worked, but there is an ongoing NATing issue
that I've been unable to resolve. I'm experimenting with openSIPS to see if it can provide the solution.</span></div>
<div><span class="ContentPasted0"><br>
</span></div>
<div><span class="ContentPasted0">My end goal is for our operations team to be able to on-board new customers by simply adding new domains and endpoints using the control panel.</span></div>

<div><span class="ContentPasted0">Thanks in advance for any help.</span></div>
