Our verdict
Retell AI is a strong choice if you want to build a voice agent your way, with your choice of LLM, voice and phone carrier. It is not a ready-made receptionist, so small businesses that just want calls answered will get there faster with Upfirst or Rosie.
Pros
- No contract; voice agents run $0.07 to $0.31 per minute
- $10 free credit and 20 concurrent calls included
- HIPAA, SOC 2 Type II, GDPR and ISO 27001 compliant
Cons
- Per-minute cost stacks: $0.055 infra plus $0.015-$0.04 voice, LLM and $0.015 telephony
- Add-ons like knowledge base ($8/mo plus $0.005/min) and extra concurrency ($8/mo each) raise the bill
- Needs setup work; it's a builder, not a turnkey receptionist
