Robocalls and simultaneous ringing
I get robocalls and junk calls about six times as often as I get "real" calls. There are some solutions out there, e.g. Jolly Roger (www.jollyrogertelco.com/), but they require simultaneous ringing. I know for a fact (googling your documentation) that you have simultaneous ringing for your business customers, just not for your residential customers. Please port this feature over! I would pay good money for it. (Yes, you "answered" this question in 2016, but time has flown! Surely you have considered your anti-robocall options in the meantime? Well, they're not working.)
