I have recently acquired a new office with an old, Executone IDS 42 phone system and all of the hardware. Is this even worth messing with? Everything worked a month ago but the old tenant's information is slim at best. I need to have a total of two lines, different from the previous owner, and my local fiber optic telecom professional just doesn't have experience with these units. Just wanted opinions on whether this is worth the hassel.
THANKS
