Teneo AI Call Guardian
Your subscribers are being targeted. Daily.
It's a problem your subscribers face every single day. Spam calls have evolved from nuisance to weapon. Millions of your customers are being defrauded, manipulated, and targeted by AI-generated voice attacks — and the only thing standing between them and the attacker is a label that says "potential spam." That's not protection. That's a warning with no follow-through.

THE SCALE OF THE PROBLEM
The phone has become the attacker's preferred weapon
This isn't background noise. It's a daily, coordinated assault on subscriber trust — landing directly on your NPS scores, your care queues, and your most vulnerable customers.
"My 74-year-old mother lost £3,200 to someone who knew her name, her provider and sounded completely convincing. I now tell her not to answer calls she doesn't recognise. She misses calls from her doctor."

WHAT THE INDUSTRY CURRENTLY OFFERS
Spam labels warn your customers. They don't protect them.
The standard response — labels, basic blocking, app-based filters — was built for a different era. It puts the burden on the subscriber and leaves sophisticated AI-powered attacks completely untouched.
TODAY: What subscribers get.
A label that says "potential spam" — then the phone rings anyway
App-based filters most subscribers never configure
No protection for elderly or vulnerable users
Zero defence against AI voice cloning
Missed calls from hospitals and schools
A growing sense that the phone isn't safe to answer
CALL GUARDIAN: What to expect
Every unknown call answered on their behalf — before it rings
A real conversation with the caller to determine intent
Confirmed threats blocked automatically
Doctors, schools, couriers passed through immediately
A transcribed summary of every screened call
Complete protection — no app, no setup, no handset dependency
HOW IT WORKS
Network-level AI — before the phone rings
Call Guardian operates at the IMS/SIP layer. The moment a call arrives at your network, it intercepts — automatically, on every device, every line, without any subscriber action required.
THREAT ARRIVES
Unknown call hits your network
An unrecognized number calls your subscriber. With Call Guardian, the AI intercepts before the handset ever rings.
AI INTERCEPTS
The AI agent answers and interviews
Call Guardian picks up, holds a natural conversation, and determines intent — in real time, in any language.
DECISION MADE
Intent determined in seconds
Scammer? Blocked. Doctor's surgery? Connected straight through. Ambiguous? Held for subscriber review.
SUBSCRIBER PROTECTED
Summary delivered. Phone never rang.
The subscriber gets a transcript of the screened call — or the phone rings because someone genuine is calling.
WHAT'S IN IT FOR YOU
The same product solves four problems at once
Call Guardian doesn't ask you to choose between commercial return and subscriber protection. It delivers both — alongside operational relief and a regulatory story that resonates at board level.
COMMERCIAL & MARKETING LEADERSHIP
A new premium revenue line, not a defensive cost
Your competitors label spam. You eliminate it. That's a product story worth a premium add-on or top-tier bundle differentiator — in a market where the pain is felt 13 times a month and no operator has solved it yet.
ARPU uplift via tiered add-on or top-tier bundle inclusion
Freemium funnel: basic blocking free, full AI screening paid
Defensible first-mover position across every European market
CX, NPS & CARE LEADERSHIP
Fewer escalations. Higher scores. Real loyalty.
Fraud complaints and spam escalations hit your care teams first. Call Guardian reduces that load at source — delivering a service subscribers can actually feel, not just read about in a welcome email.
Measurable reduction in spam and fraud-related care contacts
NPS uplift among elderly, vulnerable, and high-usage segments
A felt benefit — not a background feature subscribers forget exists
RETENTION & CHURN STRATEGY
Protect the subscribers most likely to leave
Your most at-risk segments — older subscribers, families, professionals — are also the most exposed to fraud. Solving a problem they deeply care about creates loyalty that's hard to match on price alone.
Churn reduction among highest-value and most vulnerable segments
A switching barrier based on trust, not contract lock-in
Satisfied customers converted into advocates
CEO, CDO & REGULATORY POSTURE
Be the operator that actually solved it
AI voice fraud is dominating consumer media. Regulators are watching. Being first to offer genuine network-level protection isn't just a product decision — it's a reputational one that resonates at board level.
Strong regulatory and press narrative tailwind, especially in the UK
A credible answer when asked "what are you doing about voice fraud?"
First-mover advantage before the market becomes crowded
WHAT IT MEANS FOR YOUR CUSTOMERS
Real protection for the people who need it most
This changes the daily experience of using a phone — for the subscribers who are most vulnerable, most vocal, and most likely to churn when they feel let down.
Elderly Subscriber
Most likely to be targeted — and most likely to be hurt
Before
Answers every call. Has lost money to a scam. Family told her to stop picking up. Now misses calls from her GP.
After
Every unknown caller screened before the phone rings. Doctor passes through automatically. Scammers never reach her.
PROFESSIONAL SUBSCRIBER
Can't ignore calls — but can't afford to be defrauded
Before
Answers unknown calls for work. Caught by two convincing fraud attempts. Wastes time managing unsolicited calls daily.
After
Unknown callers pre-screened. Legitimate calls connect immediately. Scams
blocked before they interrupt one working hour.
PARENT SUBSCRIBER
Worried their children will be targeted and won't know it
Before
Anxious about AI-generated calls that impersonate family members. Doesn't trust teenagers to recognize sophisticated fraud.
After
Network-level screening catches AI-generated voices. Emergency scams never reach their children's phones. No app needed.
