How should you evaluate a switch?
Build real-time voice assistants and automated conversational calling workflows. Start with a real task and compare the output, effort, permissions, and full cost. Test interruptions, latency, escalation, call permissions, and telephony costs. Include migration work, access, and cancellation terms in the evaluation. A shared category does not make two products direct substitutes.
