Robocall mitigation software
Robocall mitigation software that runs beside your switch. It stops fraud in milliseconds, answers tracebacks, and keeps call data on your host.

Compliance work, done on every call
A traceback answered in one click
Enter the number and the time. Falcon finds the call, names the upstream that sent it, and writes the answer.
FCC autopilot
Every 6 hours Falcon checks the FCC standing of the carriers that send you calls. A provider under an FCC order is flagged, or blocked in enforce mode.
FALCON_FCC=true
FALCON_FCC_MODE=monitorCovers 47 CFR 64.6305(g) and 64.1200(n)(3).
Block the signer, not the number
Scammers rotate numbers every week. Their signing certificate stays. Falcon reads the Service Provider Code on every call, so one rule stops a whole campaign.
Share telemetry. Get the network for free.
Every sharing install is a sensor on another network, so you can spot a bad signer before its calls reach you.
Local only
Runs on its own.
- Screening and STIR/SHAKEN
- Rules, tracebacks, and the dashboard
- Nothing leaves your host
FALCON_SHARE=false
Sharing
DefaultFree, and on out of the box.
- Network score for every signer and dialer tool, hourly
- The FCC autopilot list after one day
- The called number leaves as REDACTED
With a CallerAPI key
Counts from the first call.
- Network scores and the FCC list from day one
- Business Caller ID verification, free
- Spam feed and voice AI as paid add-ons
Reporters, not installs
One account counts once. A new install without a key waits 7 days.
The middle opinion wins
A score is the median. A loud minority can not move it.
Two accounts to hard-block
No single customer can block a carrier for everyone.

}Beside the switch, never in the call
Your switch asks before it sets up media, and gets an action with the reasons. If Falcon stops answering, calls continue.

Questions carriers ask
What is robocall mitigation software?
Software that screens each call before it is set up and tells the switch to allow, flag, or reject it. Falcon also verifies STIR/SHAKEN and names the provider that signed the call.
Does Falcon sit in the call path?
No. The switch keeps signaling and media and asks Falcon over HTTP or SIP. If Falcon is slow or down, the call continues.
What data leaves my network?
Redacted screening events, by default: the decision, the calling number, the source address, and the signer. The called number leaves as REDACTED. Recordings and the SDP stay on your host. FALCON_SHARE=false turns sharing off.
Is Falcon free?
Yes. Falcon is open source under Apache 2.0. Sharing installs get the network scores and the FCC list free. A CallerAPI key adds free Business Caller ID verification, and paid add-ons such as the spam feed and voice AI.
