The system is MICS with NAM. There is this Mailbox that shows "Message for you" but when mailbox is opened there are no messages inside. There is no external Voice Mail on any lines on the system and the extension associated with this Mailbox does not have any external lines assigned...

Thanks for the tip. I will try this next week. I finally heard from telco and they will try to fix it from the central office. They asked me what's the loop current required for my system. I'm not sure if this is anywhere in the specs for 8x24. I told them 27mA/48V just to be on the safe...
Executive Set "E" has line 176 and 177 Appear&Ring. Line 176 is private line to this set.
Assistant Set "A" has line 175 and 177 Appear& Ring. Line 175 is private line to this set.
Assistant wants to be able to answer Set "E" when called internally but Executive...

I didn't personally check the ground yesterday. 8 months ago when I first started troubleshooting this the doctor had an electrician check the electrical outlet and dedicate an outlet for the phone system. I mentioned to them yesterday to have SPAKY doublecheck the outlet and make sure it...

I'm sure my meter is good. I used the same meter (after getting back from the Doctor) to measure the loop current on my lines and it measures 25mA on all lines. The MICS is disconnected the line (4) is back on the 8x24. Got your point; SHOULDN'T PUT A LINE WITH SUCH HIGH LOOP CURRENT EVEN...
OK...
Will telco correct this problem if made aware?
Does anyone know if MICS tolerates this currents (over 27mA)?
Should I just go ahead and order those Loop Current Attenuators?
After taking this measurements makes sense to me that this is the problem because if you look at Line 04...
Well here are the findings:
No ALARMS and no EVENTS in the log. The Voltage on the lines looks OK but I can't say the same about the loop current:
L01 50.2V 35.2mA
L02 50.2V 35.3mA
L03 50.2V 31.3mA
L04 42.7V 39.9mA
L05 50.3V 33.9mA
L06 50.1V 33.9mA
L07 49.9V 34.1mA
L08 50.4V 34.4mA
L09 50.4V...
