What to verify across every demo

Containment results for similar call types and volumes
CCaaS, CRM, knowledge base, and identity integration work
Language coverage, accent handling, and escalation behavior
Fallback paths for failed intents and angry callers
Conversation design ownership after launch
Pricing exposure across calls, minutes, languages, and channels

Who to keep on the edge of the list

Replicant remains worth comparing if focused voice containment fits, but verify pricing and fit for a broader platform decision.

SmartAction (Capacity) remains worth comparing for high-volume use cases, then confirm roadmap and operating support.

Ada remains worth comparing if digital-first support is central and voice is part of a broader AI agent decision.
