Pros & cons
Nextiva
Pros
- Published list price for the AI receptionist, rare in this category
- Voice, SMS, and web chat handled by one agent
- Session pricing favors long intake calls over per-minute rivals
- SOC 2 certified and HIPAA compliant per the vendor, with a 30-day money-back guarantee
- Phone system and receptionist from one vendor, so there is no integration to maintain
Cons
- 50 conversations still cost $99 — no volume discounts at the low end
- Reviewers report unclear session edge cases and contradictory product pages
- Weak at capturing email addresses by voice
- Replacing your phone system is a far bigger switching cost than adding a standalone agent
- Overkill if you only need after-hours answering
Retell AI
Pros
- HIPAA-ready on standard plans
- ~620ms latency (production usable)
- Good CRM integrations
- Balanced inbound/outbound
Cons
- Smaller community than Vapi or Bland
- Some advanced flows require dev work
- Total cost depends on LLM/TTS choices
