I'd really like to have a proper answering machine for mobile: where the caller is audible whilst leaving the message, so I can choose whether to pick up (unlike voicemail). Audible calls would be fine at home; on the go it could be limited to a headset. I've looked into this before, and even hacked around a little with the freesmartphone.org stack back in the day. I've switched from OpenMoko to PinePhone since then, and haven't taken a proper look at its telephony stack yet. From Googling around, it appears that there were a few Symbian apps for this; and that Android's permission model doesn't allow any app to automatically answer calls or access their audio. PS: Based on the number of siblings talking about spam/scams, it sounds like that's a real problem in the US. Thankfully I've never had a problem with that on my UK mobile, despite having the same number for 22 years.
