01 — Overview
How does an AI voice agent work for a UK business in 2026?
It plugs into your existing UK SIP infrastructure (BT, Gamma, Vonage, RingCentral, 8x8, NFON), runs natural-language conversations in British English with sub-200ms reply latency, and takes action live in your CRM, calendar, billing, and helpdesk through the integrations you've authorised. Inbound and outbound, 100+ languages for European callers, per-resolution pricing.
UK voice AI buyers in 2026 fall into two camps. Camp one wants a developer infrastructure (Vapi, Bland, Retell) and is willing to build the agent themselves. Camp two wants a finished product they can configure in a dashboard and put in production this quarter. Open is the second.
On the SIP side, we're a destination on whatever UK carrier you already use — BT Cloud Voice, Gamma Horizon (and the wholesale platform), Vonage Business UK, RingCentral UK, 8x8 X-Series, Zoom Phone UK, NFON, Voxbone/Bandwidth. Inbound calls hit Open via SIP INVITE; outbound originates through your trunk so you keep your existing minute pricing. UK number ranges (0800, 0808, 03xx, 02xx, 01xx, 07xx mobile) all supported.
On the agent side, the AI is configured in the Open dashboard rather than built in code. You define the role (sales SDR, support agent, receptionist, outbound recall caller), point at your CRM and calendar, set the voice and language, define the knowledge base, set escalation rules. Production-grade observability is built in: per-call recordings, transcripts, reasoning traces, outcome tags, and cost-per-resolution analytics.
On compliance: UK-GDPR alignment with EU/UK data residency by default, optional UK-only pinning for regulated sectors. OFCOM Persistent Misuse rules for outbound (abandoned-call rate caps, calling hours, abandoned-call message). Recording and consent prompts configurable. ICO-aware DPA. PII redaction including NI numbers, NHS numbers, and payment cards.
Production deployments at UK customers go live in days, not quarters. The longest external dependency is usually trunk paperwork on Gamma or BT; Open itself is configured and tested same-day.
