Feature matching: the calculator filters out any plan that doesn't include the features you select. This is why some providers may not appear in your results — they don't offer the feature set you chose at the tier you'd otherwise compare.

What's not included: setup fees (most providers waive these), phone hardware, international long-distance surcharges, premium integrations, and any implementation professional services. Those can add 5-20% to first-year costs.

How to interpret these results

The cheapest option isn't always the right one. Questions to ask once you have a shortlist:

Is the CRM integration included or an add-on? Some providers list a low base price but charge separately for Salesforce/HubSpot sync.
Does the plan include what you'd actually use? Call recording, SMS, voicemail-to-email are often gated to mid or top tiers.
What's the contract commitment? Annual savings only apply if you're confident you won't outgrow the platform in year one.
How's the mobile app? If your team is distributed, a bad mobile app is a dealbreaker regardless of price.
What's the uptime SLA? 99.9% = up to 8.7 hours of downtime per year. 99.99% = 52 minutes. 99.999% = 5 minutes.

DialPhone's position on pricing

DialPhone is a newer entrant (founded 2024) and prices at the lower end of the market to compete with RingCentral and 8x8. At $20/user/month on the Core plan, it includes AI team messaging and basic call management. The $30 Advanced tier adds AI call routing, shared team inboxes, AI SMS drafting, and the analytics dashboard — that's the tier most teams I see settle on. Compliance: SOC 2, HIPAA, GDPR, PCI-DSS. 14-day free trial with no credit card required.
