What it is

Real time AI call screening and voice deepfake detection

CallScreener AI

Phone based fraud is becoming harder to recognise as attackers use caller ID spoofing, prerecorded speech, voice cloning and AI generated voices to impersonate trusted people. CallScreener AI adds an intelligent screening layer before incoming calls reach employees, customer service teams or sensitive business processes.

The platform can engage callers, understand why they are calling, examine voice authenticity and provide relevant risk indicators. Suspicious or uncertain calls can receive additional verification or be transferred to a human operator for review.

CallScreener AI is designed to support human and policy based decisions, rather than treating a single voice or behavioural signal as proof of fraud.

Sector use cases

Where CallScreener AI applies

Banking and financial services

Help protect phone banking interactions, high value transaction requests and customer service workflows from voice impersonation and AI enabled social engineering, with additional verification before sensitive actions proceed.

Insurance and claims

Screen authorised claims related calls for potential voice impersonation, prerecorded responses or unusual call characteristics, helping investigators identify conversations that need further review.

Telecommunications

Add stronger verification to sensitive customer requests such as account changes and number transfers, alongside existing identity checks.

Enterprise support and helpdesks

Help protect employees from callers impersonating executives, colleagues, customers or trusted partners, particularly on requests involving credentials, account access or financial information.

Government and public services

Screen authorised calls to public service lines for potential impersonation, automated abuse or manipulated voice, with deployment inside approved infrastructure where call information requires stricter control.

Regulated customer verification

Support authorised voice and video assisted verification workflows with call screening, voice authenticity analysis and human oversight. It complements existing identity and compliance procedures rather than guaranteeing regulatory compliance.

Deployment strategy

From telephony integration to reviewed calls

  1. Integrate with the telephony environment

    CallScreener AI is designed to integrate with modern enterprise telephony, contact centre and call management environments. The exact approach depends on the organisation's existing infrastructure and deployment requirements.

    Works with the call platform already in place

  2. Deploy within approved infrastructure

    Call recordings, transcripts and related analysis information can remain within the organisation's approved infrastructure, with the organisation defining how authorised services communicate and where sensitive call information is processed.

    Sensitive call data stays under organisational control

  3. Configure screening and verification

    Conversational questions and verification requests are configured around approved organisational procedures, so the automated first line follows the rules the organisation already applies to sensitive calls.

    Screening that follows existing procedure

  4. Set the handoff rules

    Routine calls follow the approved automated workflow, while suspicious or uncertain interactions transfer to an authorised agent with the relevant screening context already available.

    Automated first line, human judgement where it matters

  5. Review and retain

    Screening conversations and subsequent agent interactions are organised into transcripts and structured reports, with storage, access and retention aligned to the organisation's privacy, security and governance requirements.

    Review ready records, retained on your terms

Deployment that fits your telephony environment

Whether CallScreener AI is evaluated on a single line or introduced across a contact centre, the integration approach depends on the organisation's existing infrastructure, and call recordings, transcripts and related information can remain within its approved environment throughout.
