Question

Is there any way to tell who a VOIP number belongs to? How can I tell if a particular device is using VOIP services?

Answer 1

It's impossible to tell who is calling you. The VoIP services are usually used because they provide a top layer of anonymity. Someone who uses a VoIP service, can easily disconnect and then reconnect with another number. It's pretty hard to track someone who uses a VoIP number.
