I have a DX 120 and has pots lines and when calls are put on hold when the person answers the call might get droped and some times the night ringer will ring but phones wont. Has a Viking PA 2A for night ringing lines hooked in the Viking.
Have put a new DX 120 ouch and reground the system.
They are about 10 miles from local telco office.

Thanks for all response
I hope someone has an Idea Comdial are scratching there heads have changed the hold to 0 and hold recall to 0 :toast: you all.
