## The answer, as recorded

Asked on 2026-10-21 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's who I'd actually point you to, roughly in the order I'd consider them:
> 
> **1. RingCentral** - the default safe pick if you want one system to cover everything: calls, SMS, video meetings, team chat, and the deepest integration library (Salesforce, HubSpot, Microsoft 365, Zendesk). Starts around $20/user/month. It's the most feature-complete, and the cost of that is a busier interface and an admin console you'll spend an afternoon learning.
> 
> **2. Nextiva** - my pick if reliability and support matter more than bells and whistles. Advertises 99.999% uptime, starts around $15/user/month, and the per-user price gets better past ~20 seats thanks to volume discounts. Below ~19 users it's not actually the cheapest, despite the headline number.
> 
> **3. Ooma Office** - best value under about 10 users, around $19.95/user/month with no contract. It's the one I'd name for a traditional office that wants desk phones on desks and doesn't care about AI or CRM syncing. Simple to set up yourself.
> 
> **4. OpenPhone** - what I'd recommend for a solo founder or a 2-5 person team, especially if you live in a browser and your phone rather than at a desk. Shared inboxes for numbers, clean texting, cheap
