This is most likely Phone-phishing, unless your customer is really making these calls.
Someone is probably spoofing their number and making these calls. There is no way for you to track such a thing. The terminating carrier has to trace it to see where the call originated from. We have these incidents, but even Level 3 cannot trace this, since it actually never hit their network.
We verified that they did make several calls. Not as many as the complainant claimed, but a few. They're a SIP trunking customer so I can't ID the specific person, just told them to stop it. -- Carlos Alvarez TelEvolve 602-889-3003
