OneAI deploys autonomous phone agents that call inbound leads within five seconds of form submission, qualify them against configurable criteria, and warm-transfer sales-ready prospects to a live rep with an in-call briefing already delivered. The vendor reports a 70% contact rate, 38% qualification rate, and 45% handoff rate across campaigns — numbers that reflect automated cadence logic, local presence dialing, and IVR navigation rather than manual SDR effort. The platform includes A/B testing across scripts, voices, accents, and call times, with a dedicated performance team handling setup, CRM integration, and daily monitoring. Where it strains: teams that need to deviate significantly from flow-based scripts mid-campaign hit configuration friction, and the managed model means your engineers are not in direct control of the infrastructure.
