Is it possible to set up an indicator light on an analog phone (connected via a voip gateway) to notify me of voice mail?

Question

Asterisk

Let's say there is a simple wired analog phone without a display (for example, Ritmix RT-003 or Gigaset DA210 or another).

The phone has a light indicator that glows when a call is made.

Is it possible to make it glow in the presence of voice mail when connected through a voip gateway?

Is it even possible to notify about voice mail on an analog phone connected via a voip gateway?

Answer 1

In the analog telephone "protocol" there are only three states - "line busy", "line free" and "ringing". There is nothing about voice mail in it - nothing will work for you without radio destruction
