Why leading companies choose Telnyx Voice AI Agents
Unlike competitors who rely on rented infrastructure, Telnyx spent over a decade building a robust, global, carrier-grade voice network. By colocating dedicated GPUs with our telephony PoPs and deeply integrating with our voice API, we've created an unmatched foundation for voice AI agents: ultra-low latency, powerful call control, crystal-clear call quality, and global-scale reliability.
It’s a deep foundation no competitor can replicate. The best part? Because we own the stack, our voice AI agents run at a fraction of the cost of competitors.
