I am new here.
We have old Toshiba regular PBX with 15 phones (single pair ph lines)
I want to setup a IP PBX but still want to use those single pair lines.
So the best solution I would think is to use FXS Gateway (16 ports).
I know the current phones might not be compatible. So what kind of analog or digital (not IP) phones are the best to connect to the gateway without losing the functionality of office environment phone. In other words, I want to have those analog/digital phones’s functionality as close as the IP phones.
