Why Deploy with Vatel

Enterprise telephony without infrastructure overhauls

Deploying enterprise AI voice agents shouldn't require costly infrastructure overhauls. Vatel's Deployment Engine layers directly over your existing telephony setup (Cisco Webex, Yeastar, Asterisk, 3CX, Teams, Bicom, or Twilio) via secure SIP trunking. Powered by co-located speech recognition, natural language understanding, and voice synthesis models across 6 global edge nodes, Vatel AI delivers a sub-second response delay — under 700ms (412ms P50) — that allows callers to speak, interrupt, and barge in naturally. From inbound peak overflow to high-volume outbound batch campaigns, Vatel scales instantly with zero dropped lines.

Under-a-Second Latency (<700ms · 412ms P50)

Eliminates awkward robotic silences. Co-located voice pipelines ensure sub-700ms end-to-end response speeds (P50 measured at 412ms), allowing callers to interrupt, ask follow-up questions, and converse naturally.

FAQ

How Vatel absorbs inbound surges and keeps your numbers.

Yes. Vatel scales concurrently and infinitely across 6 edge regions (handling 13,744+ calls/24h). Unlike human receptionists limited to one call at a time, Vatel absorbs daytime surges and after-hours spikes with zero wait times.

No. Vatel connects over SIP trunking or call forwarding to your existing numbers and telephony setup (Webex, Yeastar, Asterisk, 3CX, Teams) without touching your current carriers or hardware.
