Inteliquent (formerly Onvoy LLC, now part of Sinch) is one of the largest competitive local exchange carriers (CLEC) in North America, processing hundreds of billions of minutes of voice traffic. Because Inteliquent sells bulk DID (Direct Inward Dialing) numbers and SIP trunks to third-party VoIP service providers, offshore scam boiler rooms frequently route Medicare, auto-warranty, and IRS impersonation robocalls over Inteliquent lines.
