You are looking for a PBX , not a VOIP system.
On a PBX ,you could have up to several hundred,if not thousand of phone numbers that you could manage on your own, incluiding the sending out of fake caller I.D.
Such a PBX will need a minimun of one digital link to the outside world.
And will work that way only on the US. Some other countries do not allow you to send a fake I.D.
And will not be a cheap option neither.Will be looking at several thousand dollars minimun.
Nope.When you send a fake, or wrong caller I.D. ,all what you do is sending the wrong “return address” information.
But that number is not avaialble on the dialing plan of the phone company.
You will not receive a call on that number.
