## The answer, as recorded

Asked on 2026-10-11 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd rank them, roughly by who they fit rather than a single "best."
> 
> **1. RingCentral** - The default safe pick if you want a real phone system, not just an app. Deepest integration library (Salesforce, HubSpot, Microsoft 365), multi-level auto-attendant, desk-phone support, strong reliability record. Starts around $20/user/mo on annual billing. It's the most expensive of the mainstream options and the admin console is genuinely complex, so it's overkill if you have 5 people and no IT help.
> 
> **2. OpenPhone** - What I'd actually recommend first to most *small* small businesses (1-15 people, no desk phones). Shared numbers with a team inbox, SMS that works properly, AI call summaries, HubSpot/Slack integrations, and a UI you can set up in an afternoon. ~$17-25/user/mo. Weak spot: it's software-only and not built for a call-center workflow.
> 
> **3. Nextiva** - Best middle ground on price-to-reliability. Core plan ~$15/user/mo annual, 99.999% uptime claim, unified voice/video/messaging, good CRM hooks. Support is its main selling point versus RingCentral. Contracts and upsell pressure are the common complaints.
> 
> **4. Dialpad** - Pick this if AI features matter to you more than
