Aircall
Stands out: Calls log back into HubSpot, Salesforce, Bullhorn, and Slack instead of living in a separate PBX.
Watch out: Plans start at three licenses, and no per-license price is published. AI Voice Agent minutes beyond the included bundle are consumption.
Not the right fit for
- Solo recruiters who want a cheap power dialer
- Teams that need LinkedIn sequencing more than voice
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
