Evaluation criteria

Know what has to work before launch

Voice quality matters, but the real test is whether the agent handles interruptions, transfers, integrations, compliance, and cost.

Latency and barge-in

Can callers interrupt naturally, and does the agent answer without awkward pauses?

Workflow completion

Does the agent actually book, qualify, route, update records, or only summarize?

Human fallback

Can sensitive, confused, or high-value calls reach the right person quickly?

Integration depth

Are calendars, CRMs, ticketing, SIP, and webhooks native, brittle, or custom-only?

Compliance posture

What claims are public, what requires contract review, and what is still buyer-owned?

Total cost shape

How do model, voice, telephony, number, usage, and support charges stack up?

Compliance and neutrality

Voice automation carries real compliance risk.

Outbound calls, recordings, opt-outs, healthcare privacy, and human escalation all need review before launch. Sponsored placement never changes editorial conclusions.
