I want to see a notice when the adapter hasn't been "seen" for a set period of time. I don't see much value in waiting for a failover event, which would affect inbound calls only.

Picking up the phone to silence is not a good thing, and the residents of the house might not know how to fix it. Since Voipo can't reboot a device it isn't connected to, at least notify us that it's missing. Please.
