What our research says

LobbyStack

LobbyStack covers the core job of a small-business phone line — answer, qualify, book, escalate — with a free tier generous enough to test it and a documented API for teams that want more control than the dashboard gives. It's a narrow tool: phone answering only, not a full helpdesk or CRM.

Pros

  • Free tier available to test before paying
  • Documented API with an OpenAPI spec, not just a dashboard
  • Outbound calling in addition to inbound answering
  • Custom/self-hosted Enterprise option for high volume

Cons

  • Voice minutes and outbound attempts are capped even on paid tiers
  • No company name or location disclosed on the site
  • No platform integrations (CRM, calendar) confirmed from the page

Rosie

Rosie fits small businesses that lose real revenue to missed calls and want a receptionist that never sleeps, without hiring one. It's self-funded and priced per-minute-bucket, so a business with unpredictable call volume needs to watch which tier they land in.

Pros

  • Trains itself from the business website and Google Business Profile
  • Direct calendar booking and call transfers on higher tiers
  • Every call comes with a recording, transcript, and summary
  • Free website chat widget included on all plans

Cons

  • Minutes are capped per tier; heavy call volume forces an upgrade
  • Only bilingual (English/Spanish), not broader multilingual support
  • Higher-tier features like priority transfers and white-glove onboarding are gated to the $299 plan
