Choice & intelligence
AI vendor agnostic
OpenAI, xAI and Gemini today, more as they mature.

Spoken natively, not through a translation layer.
Templates
Pre-built starting points for common use cases.
Prompt-with-AI
Assist tools write the prompt with you, so you don't need a developer.
Intuitive wizard

Knowledge
Advanced web crawling
You choose which pages are crawled, and how often.
Custom knowledge base
Your procedures and internal knowledge, or straight from your site.
Actions & integrations
Tools and APIs, no limits
Any REST API. The agent pushes and pulls from the systems you already run.
Call transfers
Free to any number on the Fuse 2 network, normal rates elsewhere.
Attended transfers
The agent briefs your colleague first, who can accept or reject.
Email queries to your inbox
Caller details and a summary, sent with call-back information.
Number awareness
Knows the number called and the number calling, so nobody reads digits aloud.
Insight
Transcription, summarisation, sentiment and call success
Every call, in Orca and in your inbox the moment it ends.
Analytics and insightsComing soon
Trends across category, resolution, sentiment and origin.
Safety & control
Guardrails and protected controls
Hard limits the AI can't be talked around.

-
You see everything
Live transcripts, call success scoring and full call history, with summaries tagging category, resolution and sentiment. No black box, no guessing what the agent told your customer.
-
It keeps itself current
Other agents go stale the week after launch. Ours re-reads your site on a schedule and mirrors it, new products appear, ended listings vanish.
-
Native speech-to-speech
No transcribe-prompt-synthesise chain stacking delay at every hop. Low-latency speech goes straight into the model and back.
-
The integration is already done
No SDKs to wire up, no tool plumbing to build, no model APIs to babysit. Fuse 2 has done the heavy lifting so your team doesn't have to.

Self-serve in Orca
Configure the agent yourself. The wizard walks you through it, the templates give you a starting point, and Prompt-with-AI helps you write the prompt, so you don't need a developer to get something good live.
Fuse 2 professional services
For anything more involved, our engineers build it with you: wiring your APIs, shaping and testing the prompt, setting guardrails and transfer logic, then tuning the agent once real calls are coming in.
Leisure
Bookings taken, classes checked and members answered, around the clock. The agent knows your timetable, your membership options and your opening hours, and handles the calls your front desk cannot get to.
Retail
Orders checked, stock questions answered and callers kept while queues clear. It reads your product pages, so what is in stock, what has ended and what is new stays current on the phone.
Healthcare
Appointments booked and reception pressure eased, without a hold queue. Patients are answered on the first ring, routine queries are handled in full, and anything clinical routes straight to your team.
Property
Viewings arranged, maintenance logged and tenants answered on the first ring. Applicants are qualified before they reach a negotiator, and out-of-hours emergencies still reach the right person.
Education
Parents answered, admissions queries handled and messages routed to the right office. Term dates, clubs and closures come straight from your website, so the answers stay current.
Professional services
Every enquiry answered, qualified and booked into the right diary. New matters are captured in full, and existing clients are recognised and routed to the people who know them.
Logistics
Delivery queries answered and consignments chased without a hold queue. Drivers, depots and customers all reach someone who can check the job and pass it on properly.
Hospitality
Tables booked, rooms checked and guests answered at any hour. The agent knows your menus, your availability and your policies, and takes the bookings you would otherwise miss.
-
No. Agents are agnostic of your PBX and SIP provider - you point a number at an agent and the call routes into Fuse 2's core. Nothing upstream needs to change, and your channel capacity isn't a constraint.
-
Yes, including attended transfers. The agent calls the destination first, summarises the conversation so far, and lets your colleague accept or reject the call. Transfers to any number on the Fuse 2 network are free; anything else is charged at your normal rate.
-
The configurable web crawler re-reads your website on a schedule you set and mirrors what it finds, so new products appear and ended listings disappear without anyone maintaining a knowledge base by hand. You control which content is crawled and how often.
-
Native support for over 20 languages across the platform, and Gemini 3.1 Flash Live natively supports 90+.
-
Yes. The platform is deliberately vendor agnostic. You can move between OpenAI, xAI and Gemini as their capabilities and pricing change, and we add new providers as they mature.
-
A fixed monthly cost per agent depending on whether you choose Standard or Pro, plus a per-minute rate for the model you run. Because the per-minute rate differs by provider and your volumes matter, we'd rather price it properly - book a call and we'll put real numbers against your call profile.
-
Two layers. Guardrails and protected controls sit outside the prompt, so the AI can't be talked around them. On top of that, automated threat detection monitors call content proactively and flags suspected abuse to Fuse 2 specialists for review.
-
We are a voice carrier. SIP trunking, direct routing, number ranges, interconnects and STIR/SHAKEN are our core engineering discipline, and the agents run inside our own independent carrier-grade core built on Oracle infrastructure - active/active, with zero-downtime deploys. Most AI agent vendors started from the model and treated telephony as a box to tick. It shows on the calls that go wrong.
