Installing Tailscale on an IP Phone


I’ve set up a freepbx set up to use with my landline in my hone and I use it regularly with Tailscale, on iOS and Android, as my ISP has closed off all my ports. Works great on my mobile phone.

I’d like to know if anyone has tried to install Tailscale on a Grandstream GXP1625 IP Phone and used. If yes, please help me out here and tell me how you did it. I have been looking all over the internet for a solution but I can’t find a straightforward solution, other than “hacking” into the phone to attain root ssh access.

Someone please help.
