What it is

Why ElevenLabs, and why an implementation partner?

ElevenLabs makes the most natural-sounding AI voice available, with brand-voice cloning, real-time multilingual switching and advanced turn-taking, and a Conversational AI agents product that connects to telephony through Twilio and SIP. It is the right platform when voice quality, brand and customer experience matter. Turning that into a production phone line, integrated with your systems, able to take a payment, safe in regulated settings, is an engineering job. That is what Fifty One Degrees does.

A worked example

What a production ElevenLabs agent looks like

For a high-value retailer with TV-driven inbound (anonymised), Fifty One Degrees built an ElevenLabs voice agent on ElevenLabs Conversational AI with Twilio and Stripe. The flow:

The agent answers, identifies itself, and is patient by design for an older, high-value caller base, with extended turn-taking and a willingness to rephrase on request.

It verifies the caller against the account under data-protection rules before doing anything sensitive.

It takes the order in natural conversation, then takes card payment securely via Stripe tokenisation, so no card data is stored.

It submits the order straight into the order system by API, and reports any abandoned or failed call by webhook, escalating to a human where needed.

The sales team is freed for high-margin calls; the routine orders are handled in the brand’s own voice.

ElevenLabs or Bland

Should you build on ElevenLabs or Bland AI?

Both are excellent for different jobs. ElevenLabs leads on voice quality, brand voice and multilingual experience, the right choice when the call is the customer experience. Bland AI is phone-native and built for high-volume, regulated calling at scale. Fifty One Degrees implements both and is platform-agnostic, so it recommends the one that fits your calls. The full side-by-side lives on Conversational AI & call automation.

FAQ

Questions buyers ask Fifty One Degrees about ElevenLabs

Are you an ElevenLabs implementation partner in the UK?

Yes. Fifty One Degrees builds production voice AI agents on ElevenLabs for UK and US businesses, engineering the conversation, telephony, backend and payment integrations and guardrails that take an agent from a great voice to a working phone line. A pilot is typically live in around 2 weeks.

Should we build on ElevenLabs or Bland AI?

ElevenLabs leads on voice quality, brand voice and multilingual experience, so it suits lines where the call is the customer experience. Bland AI is phone-native and built for high-volume, regulated calling at scale. Fifty One Degrees implements both and is platform-agnostic; the full comparison is on the Conversational AI page.

Can an ElevenLabs voice agent take phone orders and payments?

Yes. Fifty One Degrees has built exactly this: an agent that verifies the caller, takes the order in natural conversation, processes card payment securely via Stripe tokenisation so no card data is stored, and submits the order to the backend by API, with human handover for the edge cases.

How do you connect ElevenLabs to phone numbers?

Through Twilio and SIP integration, with local numbers across the regions you serve. Fifty One Degrees sets up the telephony, routing and fallback as part of the build, so the agent works on a real phone line rather than only in a demo.

Can it speak in our brand voice and in other languages?

Yes. ElevenLabs supports brand-voice cloning and real-time multilingual switching, and Fifty One Degrees configures the voice and language handling so the line sounds like your brand and serves the markets you operate in.

How is it different from our old IVR?

An IVR is a rigid menu; an ElevenLabs agent holds a natural conversation, understands intent, handles interruptions and acts on your systems. The experience is a person-like call that books, verifies and transacts, not “press 1 for sales.”

How long does it take to build?

A pilot on one call type is usually live in around 2 weeks, with a fully integrated version, including payment where needed, following over the next few weeks. Fifty One Degrees ramps the agent’s share of calls as it proves out.
