Build Voice Service Agents

1. Creates the voice agent from an Agentforce template and adds voice modality.
2. Builds the supporting data model: custom objects, a Contact field with field-level security across profiles, and a branded LWC for Contact record pages.
3. Writes the agent in Agent Script with phone verification, account inquiry and escalation, deploys it and tests it in preview.
4. Adds custom subagents and Apex actions, publishes and activates the version, and assigns permissions to a user.
5. Builds a flow that creates records from the call, fixing field requirements and flow XML ordering along the way.
6. Retrieves the bundle metadata so the agent script can be published, and saves the agent files as a reusable reference with documentation.

When calls still fail after the build, the next step is Diagnose Voice Agent Issues.
