If I Block No Caller ID Calls, Can I Still Reveal Them?
Like to keep No Caller ID calls blocked but still want to know who's calling? Good news, you can do both, as long as the call still reaches Traceback. Here's how it works.
Yes. Even with a No Caller ID blocker turned on, Traceback can still reveal the number, as long as the call is forwarded to us and doesn't get picked up by voicemail. The reveal depends on the call reaching us, so voicemail catching it first will stop it.
Why Voicemail Is the Key Thing to Check
Traceback reveals a hidden caller by having the call forward to us. If your voicemail answers the call before it forwards, there's nothing for us to capture, and no reveal. So the one thing to get right is making sure the call forwards to Traceback instead of dropping into voicemail.
How to Keep Reveal Working with Blocking On
- Keep Traceback's service active (Settings → Restart Service if needed).
- Make sure call forwarding to Traceback is set up and working.
- Check that voicemail isn't set to pick up these calls before they forward.
- Run a test: have a friend call from No Caller ID and decline it to confirm the reveal still works.
Privacy Note
Whether or not you block hidden calls, Traceback only uses the call details forwarded to us to reveal the number. We don't access your conversations or your past call history.
Troubleshooting
I block No Caller ID and now nothing reveals. Check that the call still forwards to us and that voicemail isn't answering first. The call has to reach Traceback to be revealed.
The call goes straight to voicemail. Adjust your setup so the call forwards to Traceback before voicemail picks up. Voicemail catching the call stops the reveal.
Reveal works sometimes but not always. This usually means voicemail is occasionally grabbing the call first. Confirm forwarding is consistent and re-run Restart Service.
