AI in Voice Firewall, working on its own.
AI that takes the action, not just the note. Running inside the network, on your brand.
Live risk scoring
AI assigns a risk score to each call setup using origin, route, CLI and calling pattern history.
Edge blocking
High-risk calls are rejected before they reach the subscriber, and the decision is logged for review.
Cross-channel learning
When the SMS engine sees a scam number, the voice engine blocks calls from it a second later.
Read the call before it rings.
- 1SIP inspection
Every SIP INVITE checked for header anomalies and suspicious origins.
- 2SS7 call control
ISUP and MAP signalling evaluated for illegitimate call setups.
- 3CLI validation
Calling line identity checked against the route it actually arrived on.
- 4Trunk monitoring
Per-trunk baselines reveal sudden shifts in call volume or destinations.
- 5Carrier-grade throughput
Processes 2,500+ voice calls per second on each node.
- 6Unified policy
Voice rules live in the same policy engine as SMS rules.
A loop that gets sharper.
- 1Mirror
Passive taps copy SIP and SS7 signalling without touching routing.
- 2Score
AI scores the call setup against route and number reputation.
- 3Decide
Policy connects, rejects or flags the call in real time.
- 4Learn
Outcomes feed back into the models during daily retraining.

Questions, answered.
Yes. The voice firewall reads SIP and SS7 signalling through the same policy engine, so mixed cores are covered.
It is rejected at the edge and logged with its risk score, and every verdict can be reversed by your team.
Yes. Call setups are scored in both directions, so fraud calls are stopped whether they arrive or leave.
Yes. Per-trunk baselines reveal sudden shifts in call volume or destinations, and a trunk group can be monitored on its own.
In real time, on call setup. Each node processes 2,500+ voice calls per second, so the call is scored before it rings.
