We are setting up asterisk on four PSTN lines and have voicemail service through our phone company. We would like to keep the voicemail set up, in the off chance that we have more than 4 incoming calls at once. Oh, and when we have voicemail, we get a stutter tone.
So here’s my question. Is there any way that asterisk can detect that I have voicemail through my phone company? And then, in turn, is there any way that I can then notify someone in the office that it’s out there?
