Hoax Calls and Call Number Display

Answered
I posted the following on "Home Phones" with not much result.

 

 

I have received a phone call from a Telstra customer on Victoria who claims that he recieved a call from Telstra stating that his phone service would be disconnected.

 

My number in Qld came up on his CND as the number that had called him.

 

I have had the reverse where I have recieved hoax calls from "Telstra" or "Microsoft" that call number display indicated business numbers around Melbourne.

 

How are these hoax callers able to display my number?

 

I am on a plan that gives me no-cost calls in Australia as part of the plan. If my number is coming up on CND for these hoax calls, are these calls debited against my plan?

 

So far I have recieved about 12 calls from people who claim that they have had a missed call from my number.

 

What can Telstra do about this?

Same as with spoofed e-mails... There is no real solution to this unless all the protocols change etc... Which is not going to happen...

I can answer only the pars of your post above:

  1. It is extremely easy to spoof caller id and to pretend to be someone else - you are just an innocent victim. Two weeks ago, I was explaining similar to someone else. This is similar to spoofing e-mails where scammers/hoaxers pretend to be from different e-mail address than they in the reality are.
  2. NO
  3. Telstra cannot do much about this, unfortunately, because it is out of their hands.

Sorry that I could not give you more satisfactory answer.

Called "Unwelcome Calls" However being a long weekend I wont hear anything until Monday. Phone off the hook today because of the volume of calls from people who have missed calls from my number.
