Hey #asterisk and #PSTN nerds, does anybody know of a way of selectivly denying calls based on what CLEC an incoming caller belongs to? Looking to deny calls coming from a specific VOIP provider that is spam/scammy. Ex: 617-516-7000 listed under https://www.npanxxsource.com/ is T-Mobile for the carrier
Yes, I know numbers can be ported around, I don't care about that level of granularity.
