I have an Executech 2000 system and am wanting to add a few single line phones to the system that will still have all system capabilities.

I realize that Comdial makes a single line phone but am wondering to use a standard 2500 type phone, should I utilize the Comdial OPX unit or can I use the ATI-D adapter?

I was under the impression that I would need the OPX unit but have also heard that I should use the ATI-D but thought the ATI-D was only for digital systems. I'm confused?!?!?!

Any help will be greatly appreciated...
