# Telnyx enables free HD Voice

### 7, Jul 2025

We’re excited to announce that HD Voice is now enabled **for free** on U.S. Telnyx numbers.

## What’s new?

Starting July 7, we’re removing the $1 monthly charge and automatically enabling HD Voice on all US long-code numbers.

## Why are we enabling HD voice for all?

Over the past decade, we’ve invested in building a full-stack carrier that’s a direct peer on the telephony network, giving us the control to offer HD voice at scale.

But our goal isn’t to sell HD voice as an add-on. Our mission is bigger than that. We’re engineering the future of voice AI, where crystal-clear, natural audio is required to deliver exceptional voice interactions.

To us, HD voice is a foundation, not a feature. We don’t upsell the essentials.

## Getting started

* No action required, HD voice is now automatically enabled for all US numbers at no additional cost.
* For optimal performance, ensure your endpoints support wideband codecs like Opus, G.722, or AMR-WB.
* See our [HD Voice Number Feature Guide](https://support.telnyx.com/en/articles/8394071-hd-voice-number-feature) for details on compatibility.

This isn’t a promotion, but a permanent upgrade reflecting our commitment to creating the best platform for [Voice AI Agents](https://telnyx.com/products/voice-ai-agents), raising the bar for the industry and accelerating what’s possible.
