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.


Yes. Pixels now do it. It’s slick.
If the phone is disconnected from the network, the provider’s voicemail service handles it.
Edit: here’s the support page describing it. It’s like old school answering machines, except that you see the live transcript, so you can decide to interrupt if you want to take the call. It’s really good.
Thanks, I’ll check this out!
