Seamless Communication with Telnyx's STUN and TURN server

In the ever-evolving world of internet communication, ensuring clear and uninterrupted calls can sometimes feel like navigating a maze. This is especially true in the realm of Voice over Internet Protocol (VoIP), where traditional networking techniques can create hurdles. That's where Telnyx steps in, offering a solution designed to streamline your VoIP experience: our STUN server.

What is a STUN Server?

At its core, a Session Traversal Utilities for NAT (STUN) server is a tool designed to improve communication through Network Address Translation (NAT). NAT is a method used to remap one IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. This is common in companies and homes with multiple devices connecting to the internet through a single router, but it can complicate direct communication between devices on different networks.

STUN servers enable devices behind a NAT to find out their public-facing IP and port number - critical information for establishing direct connections. This is particularly vital for VoIP technologies, where direct paths ensure lower latency and higher call quality.

Beyond STUN: The Role of TURN in Overcoming Communication Hurdles
