## What has to be true to appear here

- Handles live, interruptible two-way conversation, not just IVR menus or voicemail
- Reports end-to-end latency
- Can transfer to a human mid-call with context
- Provides call recordings and transcripts the customer controls

## What every product here was put through

1. Measure end-to-end response latency across 200 turns on a standard line, reported at median and 95th percentile
2. Interrupt the agent mid-sentence 50 times and measure how often it recovers gracefully
3. Run 60 booking calls with deliberate ambiguity ('sometime next week, not Tuesday') and score correct outcomes
4. Request a human three ways, including indirectly, and check every route transfers with context

## Frequently asked questions

### Will callers know they are talking to an AI?

Most will, quickly. The relevant question is disclosure: several jurisdictions now require it, and every product here can be configured either way. We report the default, and the default should be disclosure.

### What does a voice minute cost?

Between £0.07 and £0.19 a minute all-in on our September 2026 snapshots, before telephony. Telephony is billed separately by almost everyone and is easy to forget when comparing.
