Head to head

JustCall vs OpenPhone

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

JustCall

$29/user/mo 14 day free trial

Cloud phone, SMS and AI voice for sales and support teams. Team is $29/user/mo billed annually, two-user minimum.

Where JustCall fits

  • SMB sales and support teams that want calling plus SMS
  • Desks already on HubSpot, Salesforce or Pipedrive
  • Teams that want a power dialer on Pro
  • Managers who want AI call scoring on Pro Plus

OpenPhone

$15/user/mo 7 day free trial

OpenPhone now sells as Quo. Starter is $15 per user per month when billed annually ($19 month to month). A 7-day trial is on the pricing page. Recruiter use is a shared req line, SMS screens, voicemail transcripts, and API writeback.

Where OpenPhone fits

  • Recruiting teams that need a shared candidate line and SMS without a full contact-center suite
  • Desks that want Sona AI on the base plan rather than an add-on dialer bot
  • TA ops that will use the Quo API to push voicemail and SMS into an ATS
  • US and Canada calling teams that can live on Starter numbers and Fair Usage

Where they pull apart

JustCall

Stands out: Calling, SMS and CRM logging on Team, a power dialer on Pro, AI coaching on Pro Plus, and a hosted MCP server.

Watch out: Two-user minimum, so Team starts at $58/mo. The AI Voice Agent is a separate per-minute add-on, and the power dialer starts on Pro.

Not the right fit for

  • Solo users (two-license minimum)
  • Buyers who need AI coaching on the cheapest plan

OpenPhone

Stands out: Every plan includes one local or toll-free number per user, US and Canada calling and SMS, voicemail transcripts, the Quo API, and the Sona AI agent with 1,000 automation credits. ChatGPT and Claude MCP is listed on the cloud-VoIP feature page. Capterra (still filed as OpenPhone, titled Quo) is 4.2 from 64 reviews.

Watch out: Monthly Starter is $19, not $15. Business and Scale AI summaries, call analytics, and advanced CRM integrations start at $23/$35 per user per month annual. Extra numbers are $5/month. US texting needs 10DLC registration fees on top.

Not the right fit for

  • Global recruiting teams that need non-US/Canada calling as the default
  • Enterprises that want a carrier-grade CCaaS with quoted seat minimums
