How these differ from AI receptionists
Receptionists route and book. Customer service agents act inside your systems: they authenticate callers, read and update records in your help desk or CRM, and close the ticket. That takes deeper integrations and more setup, which is why most vendors here quote rather than publish prices.
Most of these vendors also handle chat and email with the same agent. We list voice capability only where the vendor says it supports phone calls.
What to check
- Pricing unit
- Per conversation, per resolution, per minute or platform fee, and how a 'resolution' is defined.
- Systems it can act in
- Help desk, CRM and contact center integrations, plus whether it can call your own APIs.
- Escalation
- How it hands off to a human agent and what context goes with the call.
- Security
- SOC 2 report, data retention controls and whether your data trains their models.
