[Crickets ...]

Was hoping for at least a pity comment from VOIPoTim. So my take away is that VOIPo mgmt probably cringes at the thought of FreePBX/Asterisk on a residential line. Too bad, other providers (e.g., voip.ms) are (apparently) more accommodating. Ironically, my VOIPo Grandstream sits there with open ports and routinely gets pinged directly from China (sometimes at 3 am) thereby bypassing any possible server screening, whereas PBX gets by with registered trunks -- no need to punch hole in firewall. Yes some dufus could try to open up their SIP functionally publicly, but I'm not sure why anyone (honest) would want to do that as remote extensions over VPN are pretty easy to do. And sneak thieves could share their line via Obi110 a lot easier than PBX anyways.

On spam calls, it's nice to see VOIPo offering nomorobo (beta) option. Unfortunately, nomorobo is surprisingly in 2017 (at least to me) heavily reliant on spammer blacklists and thus of no use to me. Around 90% of my spam calls are from boiler-room/sweatshop outfits, which use on-the-fly fake CID of [destination area code] plus [7 random digits] -- changes with each call. No matter how up-to-date nomorobo's list is in real-time, it is not effective against constantly changing fake random CID. (i guess it's good to hear some parts of the country still have "ethical" spammers that nomorobo *can* target.) Also, nomorobo uses simul-ring, so you hear at least the first ring. With a dozen or more spam calls per day, that's a deal breaker for me and THE reason why I quit using my Panasonic phone's blacklister years ago (when fake CIDs were not a problem).

So the anti-spam solution I'm going with is a verbal captcha ("Please enter the phone number you are calling from now"), coupled with the ability to optionally transfer calls to "Lenny," who is quite a hoot:

I would encourage VOIPo to up its whitelist/blacklist game, or simply give advanced users the ability to edit script rules, such as done for e-mail, e.g., Fastmail.com:
