Nortel MICS 7.1, about 10 7310, 4 7208, 1 7410CT (I know), 5 7406 on 2 base stations, 3 doorphones, 1 ASM. KSU and ASM are on a UPS.
On day last week, one 7310 decided to call another set... would not stop until the called station answered (no camp-on or busy call-back, that set hardly gets used).
Couple of days later, two of the 7406 cordless go nuts... one won't stop beeping, the other has a scrambled display. Reset their base station and things calm down.
The the cordless do more or less the same thing again... reset the main KSU (first time in ages), then the cordless base.
Now we notice none of the incoming lines are ringing... calls have been going to telco voicemail. Dialtone on all three CO lines.
Check **CONFIG programming... ALL SETS have their lines programmed to Appear, none to Appear&Ring like they were up to last Monday.
Everything else looks normal. Reconfigured the line appearances and all seems OK.
How weird is that?
