I have tried that and it didn't help.
Also I cant get into manager mailbox either.
Please forgive my ignorance on this system. What A/D port are you referring to?
Thanx
In the voicemail, logged on from a laptop, you would see that the voicemail ports say "Ans" except for one marked "A/D". That one send the signal to light and turn off msg lamps. If the port gets busied out, msg lights never change.
If you can't log into the voicemail, then this advice won't help you, and you should call out a local tech to resolve this for you.
