I'm helping a friend with an older panasonic 624 system. She has it in her home and wants all the CO's to ring on all the phones. There is a jack in the basement which I'm told is where they do the programming. What's the best way to do this? Thanks.
If my question isn't complete/self explanatory, email me at vze2m645@verizon.net.
TIA
