Where they pull apart

CallMantra

Stands out: Recruiter softphone plus SMS, ATS logging, and a power dialer on Premier, priced as a printed monthly SKU.

Watch out: The $20.95 figure is annual billing (20 percent off). Regulatory and one-time registration fees are extra. Caller ID tools start on Pro.

Not the right fit for

Sales SDR orgs that need a B2B parallel dialer
Contact centers that need CCaaS routing

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
