POTS extensions to 3CX

[taurusgd]

I want to be able to keep some wired legacy phone extensions out in the factory floor. They are currently wired into an AT&T partner system. I dont have ethernet cable out there. They are on POTS lines and I am thinking that if I put the POTS lines on an ATA device I will lose these phones. Is there a way to do this? I.e. use 3cx to call a POTS extension?
Thanks

You can connect the AT&T system (or any key system or Key system replacement) to ATA's (extensions from 3CX) just as they are now connected to POTS lines or extension off of an analogue PBX.
