Phones won't ring from a particular jack
I have an old Panasonic Intercom Phone system in my house. Regarding one particular phone jack - whichever phone I hook up to it won't ring. The same phone rings fine on different jacks. Opened up the jack and looked at wires - nothing noticeable. Replaced it with a different jack and same issue persists.
Jack wiring consists of 4 wires Blue with white, White with blu, Orange with white & White with orange.
Any ideas?

My guess is either a broken wire somewhere. It also could be the wire is disconnected at the other end where it originates.
It's also possible that jack is wired incorrectly. A phone line takes two wires but most jacks use four. If two of those four wires are crossed the phone will not work.

Is this a phone system where multiple phones are controlled by a common control unit ?
It may have a bad channel/port OR that port is programmed not to ring.
Make sure the NRS (night ring service) button is not in.

The system model is a Panasonic Electronic Modular Switching System KX-61610
I believe it is as you say - multiple phones controlled by a common control unit in the basement. Tons of wires going into the main unit.
I doubt it has anything to do with a NRS since the same phone will ring on a different jack

Ok...... by default that system is 6 C.O. lines x 16 Extensions.
You probably aren't using all 16 extension ports. Move the problem plug to a new port on the system.
