I don’t understand why voicemail really needs ti be a separate service involving forwarding and such. Couldn’t there be an app that picks up an unanswered call after a timer, plays a greeting, and records the reply? Couldn’t that all be on the device?
Or is there some technical limitation that I just don’t understand? I haven’t found any such app, and all voicemail apps seem to be services that forward calls remotely.
I never got that either. We could just have an answering machine app, a telefax app or even an corporate interactive voice response menu. I don’t think there’s any technical reason for these things not existing. It’s just audio transmitted over an audio channel.
