## The answer, as recorded

Asked on 2026-09-21 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd actually rank these, depending on your team size and what you need.
> 
> ## The short list
> 
> **1. RingCentral - the safe default for 10+ people**
> The most complete feature set out of the box: multi-level IVR, call recording, analytics, video, SMS, and the deepest integration library (Salesforce, HubSpot, Microsoft 365). It's the priciest of the mainstream options, and you'll notice that at the entry tier, but it's the one you pick when you don't want to re-evaluate in 18 months.

> 
> **2. Nextiva - best price-to-feature ratio for a traditional phone system**
> Core starts at $15/user/month on annual billing ($23 month-to-month), which is the lowest of the big three. The catch: the $15 tier skips multi-level IVR and call recording, so budget for Engage ($25/user/mo annual) if you need real call routing. Strong uptime record and it bundles customer-engagement channels (web chat, social, reviews) if you're client-facing. ([getvoip.com](https://getvoip.com/blog/ringcentral-vs-nextiva/))
> 
> **3. Quo (formerly OpenPhone) - best for 1-10 people**
> $15/$23/$35 per
