UK AI voice agents, built the way UK buyers actually buy them.
Persona gives you a choice most vendors don't. Choose UK-sovereign mode — speech-to-text, language model, text-to-speech and database all in a UK data centre on OnshoreAI, Hostcomm's own UK-hosted inference service, with no US AI company anywhere in the data path. Or choose high-fidelity mode with your pick of OpenAI, Gemini or Claude, plus ElevenLabs voices — the most natural AI voice on the market. Same telephony backbone. Same twenty years behind it. From £99 a month.
Sovereign or frontier. One of these is 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. Some need every byte to stay in the UK. Some want the raw capability of OpenAI, Gemini or Claude. Persona does both, at the same price — and we'll tell you straight which one fits.
Persona UK · Every component in a UK data centre
Speech-to-text, LLM, text-to-speech and database — all UK-hosted on OnshoreAI, Hostcomm's UK inference service: open-source models (Nemotron, DeepSeek, Llama and Kimi families) and UK-hosted speech-to-text. GDPR compliant by architecture.
- Data never leaves the UK — STT, LLM, TTS and database all in a UK data centre
- LLM run by Hostcomm — not controlled or managed by a US AI company
- Your call data is never used to train anyone's models
- No risk of models being withdrawn or deprecated on a vendor's whim
- Very low latency — sub-800ms, no Atlantic crossings
- Your choice of UK-hosted TTS and STT engines
- Fully functional — tools, webhooks and API integration, nothing cut down
Persona Premium · OpenAI, Gemini or Claude + ElevenLabs
Your pick of the frontier LLMs, with the most natural AI voice available today. For buyers who prioritise caller experience.
- Choice of frontier LLMs — OpenAI GPT, Google Gemini or Anthropic Claude
- ElevenLabs text-to-speech — indistinguishable from a human
- Optional PII redaction before upload for risk reduction
- Same Hostcomm telephony backbone and contact centre integration
- Data processed outside the UK — GDPR via contractual safeguards, not architecture
What is a UK sovereign AI voice agent?
A UK sovereign AI voice agent is a voice AI system where every processing component — speech-to-text, the language model, text-to-speech and the database — runs on UK infrastructure under UK jurisdiction, with no US AI provider in the data path. Persona UK is Hostcomm's sovereign deployment: the full pipeline hosted in a UK data centre on OnshoreAI, operated by a UK company with twenty years of contact centre telephony behind it.
Data never leaves the UK
Audio, transcripts, embeddings and stored records all remain in the UK. No international transfers to assess — your DPIA and ICO conversations get simpler, not harder.
Not controlled by a US AI company
The language model is open-source, deployed and managed by Hostcomm. No OpenAI, Google or Anthropic in the loop — and no foreign legal regime with a claim on your call data.
Never used for training
Your recordings and transcripts are never used to train AI models — ours or anyone else's. That's an architectural fact, not a clause you have to negotiate.
No model withdrawal risk
US providers deprecate models on their own schedule. Persona UK runs model versions we pin and operate — nothing disappears on a vendor's whim, and upgrades happen when you choose.
Very low latency
Every hop happens inside one UK data centre — no Atlantic round-trips. Sub-800ms end-to-end response keeps conversations feeling natural on a real phone line.
Your choice of engines. Full integration.
Pick from multiple UK-hosted TTS and STT engines. Tools, webhooks, CRM and API integration all work exactly as they do in Premium — sovereignty costs you nothing in capability.
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.
Every part of the voice pipeline, inside a UK data centre.
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
- Open-source language model on OnshoreAI in a UK data centre — no external API calls
- Neural voice synthesis on UK-hosted infrastructure
- Your DPIA becomes simpler, not harder
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
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
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

Sourced from public documentation and vendor trust pages as of 2026. "Unstated" means the vendor does not explicitly commit to UK-only processing. We update this table when vendors publish clearer commitments.

Reads and writes your systems while the caller is still on the line.
Connected from the Persona console. Persona looks the caller up as it answers, then acts in the system during the call: creates the ticket, updates the lead, books the slot, applies the offer.
Your CRM not listed? We connect it for free when you sign up. Any system with a JSON API over HTTPS using bearer-token authentication qualifies: a lookup on answer, an update at the end of the call. That covers most CRMs, helpdesks and booking systems. Anything more involved is quoted separately.
HubSpot
Find and create contacts, attach call and chat summaries as notes.
Odoo
Partners, leads, helpdesk tickets, call logging, lead stage updates.
FLG360
Look up, create and update leads; write call outcomes back.
VICIdial
Lead lookup and update, DNC check, schedule callbacks, via the Non-Agent API.
Freshservice
Log tickets to sales, support and accounts; look up by ticket number or caller.
Microsoft 365
Send email from Outlook, manage calendar events and bookings.
Slack
Post to a channel or DM a colleague mid-call when a human needs to know.
Your own systems
Custom connectors, built by Hostcomm. Standard lookup-and-update connections are free at sign-up; one UK subscription retailer's agent goes further and checks a caller's subscription and billing, then pauses, cancels or applies a retention offer during the call.
Lead ingestion API
A lead provider POSTs a number; Persona dials it immediately. Deduplicated by phone number.
PCI DSS payment IVR
Takes the card mid-call by keypad; the number never enters the language model.
Any other CRM: free at sign-up
Hostcomm builds the connection for you at no charge when you subscribe, as long as your system has a JSON API over HTTPS with bearer-token authentication and the job is a lookup on answer and an update after the call. Anything more involved is quoted.
