ABOUT

SIP Trunking built for unlimited global scale

SIP trunking allows businesses to operate a phone system over the internet instead of over physical copper lines and on-premise solutions. Telnyx customers access SIP Trunking through a user-friendly portal and flexible APIs, allowing them to stay in control and manage their global communications easily.

High-quality voice is delivered over a private, multi-cloud network that keeps communications online, even during major cloud outages. What’s more, customers are charged only for what they use—not per seat—providing cost savings from the go.
