I have an incrediblepbx 2027 install on crowncloud that I need to connect a couple polycom phones to but they are coming from a non-static IP. My clearlyip phones are no issue because they have the built in openvpn function but these polycom do not have anything like that that I can find. I saw someone post about using domain auth but cant find anything beyond that. How can I connect these polycom phones to my pbx and keep the connection secure?

I use GL-MT300N-v2 with an old IP phone to achieve the same goal.
I got it on sale for less than $20. At the time it was the least expensive among the GLiNet travel routers.

Many still available on eBay in the $25-$35 price range.
