A warning, before they answer.
Tag likely spam so subscribers see a warning before answering. MCM puts a clear label on the incoming call screen and leaves the choice to the person holding the phone.
Incoming call
Unknown caller
+1 555 010 0142
Illustrative example, not a real call
The warning arrives while it rings.
Before the answer
The label sits on the incoming call screen while the phone rings, so the warning arrives at the moment of decision.
Plain words
A short tag such as Likely spam tells the subscriber what to expect. No settings to open and nothing to install.
Normal calls untouched
A call that looks fine rings as usual. Good calls connect as they always did, because the decision is made in real time.
From arrival to a clear label.
The check runs before the phone rings, so labelling adds a warning without slowing down the calls that are fine.
- 01
A call arrives
The call reaches your network and is checked before the phone rings.
- 02
MCM AI judges it
The caller ID, the route and the calling pattern are weighed in real time.
- 03
A doubtful call is tagged
If it looks like likely spam, a warning label travels with the call.
- 04
The subscriber chooses
They see the label while it rings, then answer, decline or ignore.
A label beats a block when it is doubtful.
Blocking is final. If MCM AI is wrong, the subscriber never learns a call was missed. A label keeps the call alive and adds context, which is the safer treatment when the evidence is mixed.
Label it
For doubtful calls- The call still rings, with a warning attached
- The subscriber makes the final decision
- A wrongly judged call can still be answered
Block it
For clear-cut calls- The call is stopped before the phone rings
- The subscriber never has to see it
- Best kept for calls that are plainly abusive

Signals, not guesses.
MCM AI reads how a call behaves and where it came from. Each signal below leaves a trail that a real subscriber would never be able to spot alone.
Route versus caller ID
A local number arriving on a foreign route is a classic sign of a spoofed call.
Fake brand numbers
A number that imitates a well-known brand but does not come from it earns a warning.
Call volume spikes
Huge volumes of short calls are the signature of a robocall campaign.
Number hopping
A caller that keeps switching numbers to dodge notice leaves a trail MCM AI can follow.
You decide how firm to be.
Choose the action
For each kind of call, decide whether it is blocked outright or let through with a scam warning label.
Keep the review loop
Labelled calls and their sources can be reviewed in the Command Center, so the team sees what is being tagged.
Make it your brand
Resell the labelling to partners and enterprise customers under your own logo.
Built for the networks that carry the calls.
Labelling is a visible sign that your network is looking after its subscribers, and subscribers notice the difference the first time a warning saves them a wasted call.
Mobile operators
Launch a call firewall for subscribers, with labels that explain what is calling and fewer complaints about unwanted calls.
Carriers
Protect your own subscribers at the edge of your network, and keep the final choice with the person who owns the phone.
Wholesale partners
Resell Voice Shield to partners and enterprise customers under your logo, labelling included.
Hard blocks for the worst calls
Labelling suits the doubtful middle. Robocall blocking handles the calls you want stopped before they ring.
