We've Got Answers You're Looking For

Everything you need to know about our AI Voice Agent solutions for your business.

How quickly can you implement AI Voice Agents?

Depending on your current call system setup, deployment of AI voice agents can take anywhere from 2 weeks to 2 months depending on the complexity of the setup. A straightforward single voice agent or voice chatbot can usually be built, tested and deployed within 2 weeks. Contact us for an accurate timeline based on your requirements.

How can voice agents answer difficult questions?

Our AI voice agents are trained on your specific business knowledge, products, and processes.

They handle complex queries through advanced natural language processing and can access your company databases in real-time using a system called RAG (Restrieval Augmented Generation) meaning that they can instantly handle complex service queries or questions about products in-depth.

For questions beyond their scope, agents seamlessly transfer to human staff with full context of the conversation, ensuring customers never have to repeat themselves. The system continuously learns from these interactions to handle similar questions independently in future.

Can I customise the voice or accent?

Absolutely. Choose from 100+ professional voices and accents to match your brand personality (even Scottish accents!). We can even clone your voice or a team member's voice for authentic brand representation.

Our AI voice agents also speak 79 languages, giving you instant access to multilingual customer support without hiring additional staff.

What if callers use profanity or go off-topic?

Unlike other providers, we build our AI voice agents with robust guardrails and comprehensive prompt engineering. If a caller uses profanity the voice agent will have a set of rules to follow - e.g. hang up, or forward the call to a human agent. The AI voice agent is also able to handle convuluted or off-topic conversations, and able to either get back on track or follow rules such as transferring to a human. Contact us for more information about the safety guardrails we implement into our voice agents.

How much do voice agent calls cost?

Call costs typically range from £0.003 to £0.30 per minute, depending on the AI model and complexity required for your business needs. Most businesses see significant savings compared to human staff costs.

For an accurate cost projection based on your call volume and requirements, contact us for a free quote. We'll show you exactly how much you could save each month.

Do I have to change my number to use a voice agent?

No. Your voice agent works with your existing phone number and setup. We integrate seamlessly with your current phone system, so customers continue calling the same number they always have.

If you still prefer human answering during operational hours - your AI voice agent can operate on your existing number out of hours to answer when nobody is around.

The transition is invisible to your customers—they'll simply experience faster, more consistent service from day one.

Can an AI Voice Agent take payment over the phone?

Yes, we can design AI systems that can perform certain actions directly over the phone such as taking payment using a payment provider such as Worldpay, Stripe, Paypal etc. to complete a purchase.

There are also numerous ways we can integrate failsafes and checks, including via SMS auto-responses and manual approvals. To discover what an AI voice agent can do, book your free strategy call to discuss your requirements in depth with us.

How many calls can an AI voice agent handle?

Unlike a single human call operator, AI voice agents can handle multiple concurrent calls at the same time. Concurrent call limits will depend on your business requirements and volumes - most high quality voice agents we build can handle up to 5-10 calls simultaneously per agent.

Are AI voice agents secure?

Yes, we build our AI voice agents with security front of mind. Our voice agents are GDPR compliant, and can be built with ZDR (Zero Data Retention) which means the transcripts or call recordings are never stored. Any PII (Personally identifiable information) is always redacted from any observable transcript and recording - and only ever used to fulfill outcomes - e.g. booking meetings, updating CRMs, or transferring to human operators.
