Hi,
I have an intermittent problem with telephone(s) NOT RINGING when someone tries to call. Most of the time, the telephone will ring. Therefore removing all devices from telephone line, then connect one device at a time to find "culprit", is not practical. Note: I removed 3 devices I seldom use from phone line. Ringing voltage increased to 81.VAC (3 devices removed) due other devices loading.
At main input jack, everything disconnected (no loads), ringing voltage was 93 VAC.
I am retired electronic technician. I used my Fluke DMM with "Max/Min" capture feature to log the ringing voltages. Twice, I was able to "capture" the NO RINGING voltages, 34.4VAC and 38VAC.
TEMP SOLUTION:
Since my answer machine is on all the time, and answers on the
4th ring, I told my relatives & friends to hang up if phone rings 5 or more times. Then call again. The odd thing (good thing), when they call back, the phone(s) ring!! So far, every time.Did anyone else have this issue?
Thank You in advance, John
