Owned infrastructure makes the difference
By owning and operating our own infrastructure, Telnyx minimizes latency and enhances call quality of AI Agents in ways that Retell AI 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, keeping traffic anchored near end users, and delivering sub-200ms round-trip times for real-time voice AI. This level of control ensures consistent, high-quality interactions at scale while eliminating the dependency on third-party networks that introduce variability and slow down conversations.
