Before you decide
Copilot Studio Voice: Per-user/month Dynamics 365 Contact Center licensing with Copilot pay-as-you-go credits, plus Azure and telephony costs. Pipecat: Open-source framework is free; Pipecat Cloud bills hosting per active minute, with transport and provider services billed separately or bundled for enterprise. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded knowledge and data sources for Copilot Studio Voice include Not publicly documented. For Pipecat, they include Not publicly documented. Ask each provider to demonstrate access for the exact systems you use, with permissions, freshness, and failure behavior. A source missing from this directory is not proof that a provider cannot support it.
Use the same representative calls, approved instructions, and escalation rules in both pilots. How does it handle interruption and uncertainty? Which actions can it complete, and which require approval? What context reaches a human during transfer? Record conversation quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Copilot Studio Voice: Product names, licenses, previews, and architecture vary. Require a bill of materials for Copilot, Dynamics, Azure, telephony, and services. Pipecat: Not a packaged phone agent. Production state, safety, testing, compliance, model bills, and carriers remain implementation work.
