AI for call centres.
Tier-1, SDR, overflow.

An AI overlay on your existing call-centre stack — Twilio, Five9, Genesys, Talkdesk or Asterisk. Handles tier-1 inbound, runs the outbound SDR motion, covers after-hours overflow, and writes every call to the CRM. UK PECR/ICO/TPS and SA POPIA/NCA compliant by design.

Built for: UK contact centres (25–2,000 seats) and South African offshore centres serving UK or US clients. Telco, utilities, financial services, debt collections, B2B SaaS, e-commerce.

Capabilities

What an AI overlay actually does.
On the stack you already run.

  1. Inbound AI tier-1 — every call, every queue, no wait

    Account balance, order status, booking changes, password resets, simple FAQ. The AI handles 60–80% of tier-1 volume end-to-end. Complex queries escalate to a human with the full transcript and the AI's recommended next action.

  2. Outbound AI SDR — qualified meetings on the calendar

    Pulls leads from CRM, dials at scale, qualifies on your framework, books human-AE meetings, writes call summaries. 3–5× the dial volume of a human SDR. TPS-screened (UK) and POPIA-consented (SA) by default.

  3. After-hours + overflow coverage

    Calls that hit a full queue or arrive outside agent hours get an AI agent instead of a hold tone. For UK centres covering global hours and SA offshore centres serving UK/US — closes the 24/7 gap without scheduling night shifts.

  4. Call summarisation + CRM write-up

    Every call — AI-handled or human-handled — gets transcribed, summarised, dispositioned and written to the CRM automatically. Agents stop spending 15–30% of their day on wrap-up. Quality monitoring gets 100% call coverage instead of 1–3% sampled.

  5. Native to your stack — Twilio, Five9, Genesys, Talkdesk, Asterisk

    No platform migration. The AI overlays your existing telephony, CRM, WFM and QM systems. Live in 4–8 weeks instead of the 6–12 months a Genesys/NICE replacement takes.

  6. Compliance by design — UK PECR/ICO + SA POPIA/NCA

    TPS screening, consent capture, two-party-consent recording, AI-disclosure on call open, NCA/NCR-aware flows for credit-regulated campaigns, PCI-DSS-aligned pause-and-resume for card capture. A named human supervisor signs off every deployed flow.

The questions COOs and heads of CX ask

AI call centres,
answered.

Are there AI call centres in the UK and South Africa?
Yes. AI-augmented call centres are live in both markets. The 2026 reality: the fully-autonomous "no humans" call centre is still rare, but hybrid AI + human centres are now the operational default for any centre above ~25 seats. AI handles tier-1 inbound, after-hours overflow, outbound list qualification and call-summary write-up; human agents take the escalations and complex sales conversations. UK enterprise centres (utilities, telcos, banks) are furthest down this path; South African offshore centres are adopting fast because the cost-per-interaction maths is compelling.
Is AI cold calling legal in the UK?
AI outbound calling is legal in the UK with caveats: (1) you must screen every dialled number against the TPS (Telephone Preference Service) before each campaign — calls to TPS-registered numbers without prior consent are an ICO offence under PECR; (2) consent for marketing calls must meet UK GDPR standards (specific, informed, freely-given); (3) the AI must identify itself as automated or AI at the start of the call; (4) call recording requires two-party-consent disclosure. Our UK call-centre deployments include TPS screening, ICO-aligned consent capture, recorded disclosure and a documented compliance protocol. See /is-ai-cold-calling-legal-uk for the full breakdown.
Is AI outbound calling legal in South Africa under POPIA and the NCA?
Yes — with the same structural caveats as the UK plus two SA-specific ones: (1) POPIA consent must be on file before any direct-marketing call to a consumer; (2) National Credit Act-regulated activity (debt collection, credit-related sales) requires the caller (human or AI) to be a registered debt collector or authorised credit provider where applicable. Our SA deployments include POPIA consent capture, NCR/NCA-aware call flows for credit-related campaigns, and POPIA-compliant call recording.
How much does an AI call centre cost?
The economics split into three layers: (1) AI infrastructure (voice + LLM tokens) — typically GBP 0.04–0.12 per minute or ZAR 0.80–2.40 per minute depending on voice quality and call length; (2) telephony minutes through your carrier (Twilio, Vonage, your existing PBX); (3) FrictionZero implementation and operational support. Versus a UK contact-centre agent FTE at GBP 28–42k all-in (or SA offshore agent at ZAR 180–280k all-in), AI capacity costs 20–40% of the equivalent volume — with no shrinkage, no schedule adherence and no after-hours premium.
Will AI replace call-centre agents?
Not wholesale — but the role shifts. Tier-1 repetitive work (account balance lookups, status checks, reset flows, simple bookings, outbound list qualification) is now AI-default at any centre serious about cost-per-interaction. Tier-2 and tier-3 (complex troubleshooting, retention saves, high-value sales, complaint resolution) remain human. Centres that adopt AI typically reduce tier-1 headcount 30–50% over 18 months while growing tier-2 specialist headcount — because they finally have capacity to take more calls.
Does it work as an AI SDR for outbound B2B?
Yes — this is one of the fastest-growing use cases. The AI SDR sits on top of your dialler (Twilio, Five9, Talkdesk or a custom Asterisk setup), pulls leads from your CRM, qualifies on a structured framework (BANT, MEDDIC, or your bespoke playbook), books meetings into a human AE's calendar, and writes the call summary to HubSpot or Salesforce. Typical outputs: 3–5× the dial volume of a human SDR at 30–50% of the cost per booked meeting. Crucially: the AI must be configured for honest disclosure — we will not deploy SDRs that pretend to be human.
Which contact-centre platforms does it integrate with?
Twilio, Five9, Genesys (Cloud CX and Engage), Talkdesk, NICE CXone, Avaya, 8x8, and custom Asterisk / FreeSWITCH setups. CRM-side: HubSpot, Salesforce, Pipedrive, Zoho, Microsoft Dynamics. Workforce management: Calabrio, Verint, NICE WFM. Quality monitoring: Observe.ai, CallMiner. The AI sits as an overlay on your existing stack — no rip-and-replace.
Why does FrictionZero work with South African offshore centres specifically?
South Africa is one of the world's largest English-language offshore call-centre hubs (BPESA reports the sector employs >290,000 people and is targeted to hit 500k by 2030). UK and US enterprise buyers are already used to SA centres; layering AI on top of an SA centre delivers the SA cost base plus the AI efficiency multiplier. Our SA deployments include UK-accent and US-accent voice options for offshore-served clients, POPIA compliance for SA-resident data, and dual-currency reporting.
