HOW IT WORKS
Three simple steps. Total control.
Choose who gets through, set your rules, and let Wall handle the rest.
02
Unknown callers can pay to connect
An AI receptionist asks why they're calling. If the reason doesn't match an expected call, they can pay your toll to connect.
03
You stay in control
Trusted people pass. You can review what happened and change a rule whenever you want.
WHO GETS THROUGH?
You decide.
One number can have different rules for different people.
Trusted contacts
Import the people you already know. They ring straight through without meeting the gate.
Expected callers
Add the call you are waiting for. Wall listens for a matching reason and lets them through free.
Magic Word
Share a private phrase with someone you trust so they can bypass the toll.
Unknown callers
An AI receptionist asks why they are calling before your phone ever rings.
Paid connections
If their reason does not match, they can pay your toll before connecting.

PRIVACY & TRUST
Your phone stays yours.
Birln Wall gives you a controlled layer between your phone and people you have not approved. It is transparent about how that layer works.
Read the privacy policyChoose your setup
Use your Birln Wall Burner Number, or easily forward calls from your current number.
Wall screens what reaches it
Trusted contacts pass. Unknown callers meet the rules you set. Turn forwarding off to return calls to normal.
Your contacts have one purpose
They are used to recognize who should get through. Birln Wall's policy says they are not sold.
Review every decision
Blocked attempts and voicemail activity stay visible, so a call does not simply disappear without context.
FAQ
Good questions. Straight answers.
Do I have to change my number?
No. You can easily forward calls from your current number to your Wall. Or use your included Burner Number as a separate line.
What happens to people in my contacts?
People you approve bypass the gate and get through without paying a connection toll.
How do expected callers get through?
You can use a Magic Word or tell Wall what kind of call you are expecting. A caller who clearly matches that expectation can receive free access.
Can I turn the Wall off?
Yes. Setup is fast, and turning it off is just as easy. The app shows the exact carrier code, so you can switch Birln Wall on or off whenever you want.
