Initiate a PSTN phone call via UponAI infrastructure. The workspace is inferred from the unique agentId. You may still send workspaceId for backward compatibility. Native-transfer workspaces expose the full per-call override surface, including agentOverride, overrideAgentVersion, customSipHeaders, and ignoreE164Validation.
