Where they pull apart

Five9

Stands out: A published Digital seat at $119 for digital-first CX, with AI contact-center tools on higher bundles.

Watch out: Plus, Pro, and Enterprise still need sales. $119 is a digital bundle, not a full voice contact center by default.

Not the right fit for

  • SDR teams that only need a power dialer
  • Recruiters who want a $20 staffing softphone

RingCentral

Stands out: LLM plugins and MCP connectors bring calls, texts and chat into ChatGPT and Claude at no extra cost.

Watch out: CRM integrations start on Advanced, not Core. The 14-day trial is for new subscribers and excludes SMS. Taxes and fees are added to list prices.

Not the right fit for

  • SDR teams that only need a power dialer
