Owned infrastructure makes the difference

Telnyx owns and operates its own infrastructure, which minimizes latency and enhances call quality in ways that Vapi cannot match.
By running AI processing and media handling on a privately owned global IP network, Telnyx avoids the delays and congestion of the public internet. Traffic stays anchored near end users, delivering sub-second round-trip times for real-time voice AI.
This level of control ensures consistent, high-quality interactions at scale while eliminating dependency on third-party networks that introduce variability and slow down conversations.
