Building AI Voice Agents at Scale: Implementations, Tradeoffs, and Enterprise Considerations
A decision framework for how much of your voice agent stack to own, and how much to delegate to a vendor.

The strategic question is no longer whether to adopt voice AI, but how to implement it in a way that balances quality, control, speed to market, compliance and scalability. For most enterprises, that comes down to how much of the orchestration they want to own.
This guide starts with the technology stack behind a conversational voice agent (telephony, turn-taking, STT, LLM and TTS), then compares the three dominant implementation approaches: building with blocks, orchestration-first products, and hybrid.
A comparison matrix covers cost, time to value, control, latency, team requirements and compliance, and three case studies (Telus Digital, Meesho and Funding Societies) show how each path plays out in practice.
Written for technical leaders and heads of AI weighing a full build, a managed product, or a middle path.
