Thanks for who you are
Today I use a raspberry with openvpn to open the vpn channel to freepbx
But I’m looking for a more reliable solution, sd corrupt one or two times a year …
I will try with the directions of the grandstream forum
In addition I had already seen the GL-MT300n and I try very much that I do not understand well … but has it inside a linux or wrong? Does anyone know anything about it?
