How build vs buy voice AI works on Voxovo
Quick answer: Voxovo helps you ship phone agents that book, qualify, contain, and escalate — with Presence Buffer so callers never hear dead air while tools or LLMs think.
Unlike chat widgets, a Voxovo agent can answer your company number, dial leads, book appointments, qualify inbound demand, update Live Sheet rows, schedule with Live Calendar, and warm-transfer to humans when needed.
For "Build vs buy for AI phone agents", start by clarifying the caller outcome: containment, booking, payment promise, qualified meeting, or structured ticket. Write that outcome into the agent prompt and first message.
Teams choose BYO telephony so carrier numbers and minutes stay on their own accounts. Voxovo bills AI credits for STT, LLM, TTS, Presence Buffer, and platform features — not your phone bill.

Voxovo 1.0 Speed prioritizes sub-second turns for bake-offs and high-volume queues. Smart trades a bit of latency for stronger reasoning. Ultra targets speech-to-speech naturalness when available for your language.
Presence Buffer pre-caches filler audio per voice and language so tool calls and slow LLM turns do not create dead air — a practical differentiator versus platforms that leave silence.
Live Sheet and Live Calendar are first-party mid-call tools: agents can read/write structured data and book without fragile Zapier glue, or sync Google when you prefer.
Measure what matters: STT, LLM, TTS, and full turn latency on every Test Live and production call. Publish scorecards in bake-offs instead of marketing claims.
