Shut the gate on the flood.
Stop floods of automated, spam and nuisance calls at the edge. Genuine business calls on your allowlist go straight through.
A flood leaves a trail.
To a subscriber it is one more unwanted ring. To the network it is a pattern, and the pattern is what gives it away.
Short calls
Many calls that end almost as soon as they start. The goal is to make a phone ring, not to hold a conversation.
Huge volumes
The same source dialling at a scale no genuine caller would. A spike is the first thing that stands out.
Number hopping
When one number gets noticed, the campaign moves to another. Followed one by one, the calls look unrelated.
Decided before anyone is disturbed.
Each call is checked as it arrives, one at a time, while the flood is still outside. Most calls are simply good calls and carry on untouched. Only the ones that fit a flood pattern meet the gate.
- 01
A call arrives
The signaling reaches the edge of your network before the call is routed to a subscriber.
- 02
The pattern is read
MCM AI checks how the call behaves: its length, its volume and whether the number keeps changing.
- 03
An action is chosen
A flood call is blocked, rerouted, flagged or has its number masked. A call on the allowlist passes.
- 04
The source is shut
The sender goes on the live threat list, so the campaign stops spreading.
Earlier is quieter.
The best moment to stop a nuisance call is before it exists for the person on the other end.
Before a phone rings
Blocked at the edge, a flood call never disturbs a subscriber. Nothing needs to be installed or tapped on the handset.
Before it spreads
Shutting down the source early stops the campaign reaching further numbers on your network.
Without slowing the good
The decision is made in real time, so a genuine call connects as usual.
Four ways to answer a suspect call.
Not every call deserves the same response. Pick the action that suits each case, and soften it where you want to.
Block
Stop the call outright, before the subscriber's phone rings.
Reroute
Send the call somewhere else instead of straight to the subscriber.
Flag
Let it through with a scam warning label, so the subscriber knows what to expect.
Mask CLI
Hide the caller's number on a suspicious call.

Genuine callers walk straight in.
A strict gate is only useful if it does not block the people you want. Allowlists keep genuine business and PBX calls flowing without false blocks.

Illustrative, fictional names. Not real customers.
Built for the networks that carry the calls.
Robocall blocking sits where calls enter the network, so it suits anyone who runs that network or resells access to it.
Carriers
Subscribers blame the network for every nuisance call. Stopping the flood at your edge protects them and the trust they place in you.
Mobile operators
Launch a call firewall under your own brand, with the choice of blocking a call or letting it through with a label.
Wholesale partners
Resell robocall blocking to partners and enterprise customers under your logo, with allowlists for the callers they depend on.
One gate in a wider wall.
Warn instead of block
Some calls are unwanted but not harmful. Spam call labelling lets them ring with a clear tag.

Blocked calls and their sources surface in the Command Center, so your team can follow the pattern.
