Would setting up ZeroTier and adding their machine to it be a solution?
Yes, VPNs will essentially always solve this. The problem is that it is often a physical phone without a VPN built it. So it ends up being a lot of effort.
So this user had a Yealink T46s. (my favorite phone) I know that this has VPN capabilities, but I have not looked into how it works with FPBX. Have you?

OpenVPN. You can do it to the PBX, or you can terminate elsewhere. PBX doesn't care. It's like a honey badger with VPNs.

Do you need SysAdmin Pro for that?

You might. Although you can do it manually without that. But the GUI would be nice.

I'm curious why DuckDNS is picking up on the VPN IP instead of the local one? no split tunneling?
Any possibility that the home user has a router that supports DynDNS? If so, set that up should solve the problem.

Good call on the split tunneling. Checking...

If it doesn't split, then the phone traffic is likely going down the tunnel, too. Or else you are checking from a different location than the phone.

Not likely, if its a full tunnel the external ip WILL always be the IP of where the tunnels ends with everything flowing through the tunnel.

Are you assuming a softphone?
I was assuming a physical phone. -

I was assuming a physical phone.I'm assuming the two on the same network component, regardless of hard or soft.

No, more typical it that the VPN is on the laptop. So only that is affected.
And it is a desk phone as noted someplace above. So not affected by the VPN.

I was assuming not based on it being typical, but that it would only have been set up this way if they were on the same network, otherwise the behaviour would be expected rather than surprising.

I suppose I can see where you are coming from - but I disagree.
I agree with JB that it seems more likely VPN only on the laptop and Split Tunneling wasn't enabled which is causing the DDNS to not function as desired.But we're waiting on the Op to confirm.

Phew! Busy couple of days for me. Sorry for the late reply.
OK, so the setup is as @JaredBusch assumed. VPN on the Laptop only. Split tunneling was not enabled and now it is. Problem solved for now! DuckDNS is reporting the correct home IP. No need for VPN on the phone or PBX.
Good call @Dashrender
@scottalanmiller I'm still going to checkout the possibilities of OpenVPN though. Just in case I need it in the future.
Thanks guys. Have a great weekend.
