Three providers that UK businesses compare most often after RingCentral. I deploy all three. Here is the side-by-side.
Quick Comparison

|---|---|---|---|
| UK price/user | £24 | £20-39 | £22-36 |
| Everything included? | Yes | No (tiered) | No (tiered) |
| Contract | Month-to-month | 12 months | 12-36 months |
| Call quality (MOS) | 4.3 | 3.9 | 4.0 |
| Mobile app rating | 4.7 | 4.2 | 4.1 |
| Support response | 3 min | 12 min | 15 min |
| UK data residency | Yes | Partial | Yes |

The Real Cost (25 users, all features)
| Feature | DialPhone | Vonage | GoTo Connect |
|---|---|---|---|
| Base plan | £600 | £500 | £550 |
| Recording | Included | +£125 | +£100 |
| Video | Included | +£250 | Included |
| Analytics | Included | +£75 | +£75 |
| Total/month | £600 | £950 | £725 |
Vonage's £20/user headline becomes £38/user with features. GoTo's £22 becomes £29.
My Verdict
- Under 50 users, UK-focused: DialPhone
- Need Vonage API for developers: Vonage
- Need video-first with basic calling: GoTo Connect
Try all three. The trial will tell you more than any comparison article — including this one.
