app idea: voice call routing / screening

[qxotk]

Setup an inbound phone number to receive calls (a la twilio) to use onename id attributes to find the owner of the calling number. If not found then route the call through a screening process to vet the caller. Could keep a list of known good numbers and know undesired numbers in profile for use in future calls.

I want this because spam, only thing Blockstack brings is verifiable white list opportunity, I think. Plus not sure if this would only temporarily mitigate as would not bad actors be able to setup spoof Blockstack profiles?

All input appreciated.
