I’m helping out a non-profit who has a Telrad system thats around 18 years old.(I take care of computers and know little about phone systems but they asked me to look at it.

Normally an incoming call gets answered by the auto attendant. But now it just rings. And we found that calling another extension does not get the voicemail.

Looking at the box in the basement, I think I hear a faint clicking (from the hard drive?)

They realize They have to get a new system but for the short term is there a way to program all the phones to ring when there’s an incoming call? Right now the line lights are flashing green on all the phones but no sound. If they see it flashing, they can answer it. But not everybody’s watching the phone all the time to answer
