Hi James — I can see your March bill came to £48.12, that's £11 more than usual. Looks like there were two international calls to Spain on the 14th. Would you like me to explain the rates, or transfer you to billing?

One of these will be right for you. We'll help you pick honestly.

Most vendors push you toward one answer. We think different UK buyers have genuinely different needs — and pretending otherwise wastes everyone's time.

What's Inside

Not a chatbot with a microphone. A real contact centre voice platform.

Built on twenty years of telephony engineering. Real SIP integration, real human handoff, real memory across calls.

UK Data Sovereignty

Every part of the voice pipeline, inside AWS London.

When procurement asks where voice data is processed, most vendors give you a corporate headquarters address. That's not the same as data residency — and the ICO knows the difference.

  • Speech recognition on UK-hosted models inside your VPC
  • Open-weights language model in AWS eu-west-2 — no external API calls
  • Neural voice synthesis on UK-hosted infrastructure
  • Your DPIA becomes simpler, not harder

Long-Term Memory

Persona remembers your callers. Even months later.

Most voice agents treat every call as the first. Persona uses a knowledge graph to remember customer preferences, past complaints, account details and conversation outcomes — so your voice agent picks up exactly where the last call left off.

  • CallerID and email recognition — no IVR menus, no account numbers
  • Full call history retrieved in under 50ms
  • Real-time business data via webhooks — CRM, housing, billing
  • PII redaction before anything hits the LLM

Human Handoff

Warm-transfer to real agents, with full context.

Not every call should end with the AI. When Persona detects complexity, escalation is instant — and the human agent receives a transcript and summary before they even say hello.

  • Transfer to internal SIP extensions or external numbers
  • WebRTC client for voice, video and chat — no app download
  • Direct BT Wholesale interconnect for carrier-grade call quality
  • Autonomy dial: set AI independence per channel

Secure Payments

Take card payments mid-call. Without pulling PII into the LLM.

Hostcomm is a PCI DSS Level 1 service provider for the fifth year running. Persona can take a payment mid-conversation by handing off to a secure payment IVR — the card number never enters the language model.

  • Pre-integrated with Stripe, Sage Pay, Barclays and Adyen
  • DTMF card entry for the PCI-sensitive moment
  • Persona resumes the conversation afterward with full context
  • PCI discipline applied across the whole Hostcomm network

The Questions We Get

Answers that hold up in an IG review.

These are the questions we hear in every DPIA meeting and every procurement call. The answers are the same every time.

Ask a different question →

Which mode should I choose — UK-sovereign or high-fidelity?
Choose UK-sovereign mode (Persona UK) if you are in healthcare, financial services, public sector, legal, or any business where data residency is a hard procurement requirement. Choose high-fidelity mode (Persona Premium) if voice naturalness is the top priority and your data protection stance permits US processing. Both modes use the same Hostcomm telephony backbone — you can even run both simultaneously for different customer journeys.
What is a UK AI voice agent?
A UK AI voice agent is an autonomous voice AI system that handles inbound and outbound phone calls where data residency and telephony infrastructure are UK-based. Hostcomm offers two deployment modes under the Persona brand — a fully UK-hosted mode for strict GDPR compliance, and a US-LLM mode for the highest voice quality available today.
Where is Persona's voice data processed?
In UK-sovereign mode, all voice data — speech-to-text, the language model, and text-to-speech — is processed inside Amazon Web Services region eu-west-2, located in London. No audio, transcript, or derived data leaves the UK. In high-fidelity mode, the language model and TTS are processed by OpenAI and ElevenLabs respectively on US infrastructure, under their standard DPAs. See the full data flow →
Is Persona UK GDPR compliant?
Persona UK (sovereign mode) is UK GDPR compliant by architecture — meaning the data residency guarantee is enforced by the infrastructure itself. Persona Premium (high-fidelity mode) is UK GDPR compliant via contractual safeguards with OpenAI and ElevenLabs under their Standard Contractual Clauses — which many UK buyers find acceptable but some regulated sectors do not. Hostcomm is an ICO-registered data controller and processor.
How does Hostcomm compare to Retell, Vapi, or Aircall?
Hostcomm is the only vendor in our comparison where UK-only data residency is committed architecturally rather than contractually. Retell and Vapi are US-based; Aircall does not publish a UK-only processing commitment for its voice AI stack. Hostcomm additionally holds PCI DSS Level 1, G-Cloud 14 listing, and a direct BT Wholesale interconnect — none of which the US vendors offer.
Can I procure Persona through G-Cloud or CCS?
Yes. Hostcomm is listed on the UK Government Digital Marketplace under G-Cloud 14 and is an approved Crown Commercial Service supplier. NHS trusts, local authorities, central government bodies and charities can purchase Persona through standard framework agreements without a separate tender.
How quickly can Persona be deployed?
Typical deployment takes days, not months. A simple use case — FAQ handling, appointment booking, lead qualification — can be live within a week. Complex integrations with CRM, housing management, or healthcare systems typically complete in two to four weeks. A free trial lets you evaluate Persona against a real call flow before commercial commitment.
Is Persona suitable for outbound as well as inbound?
Yes. Persona integrates directly with Hostcomm's predictive dialler for outbound campaigns — rent reminders, payment collection, appointment confirmations, customer satisfaction surveys, renewal outreach. The same agent configuration handles both directions with appropriate guardrails.

Twenty minutes. One demo. Both modes on the line.

Bring your toughest information governance question. We'll show you the architecture for both modes, hand over the DPA, and put a live agent on a real phone number — all in the same call.
