06/26/2025, 6:04 PMTo configure your SIP trunk to use the G.722 codec for HD Voice with LiveKit SIP, please follow these steps (specific to Telnyx):
1. Enable the HD Voice feature on the phone number you want to use. This can be found under Number → Voice in the Telnyx portal.
2. Enable the G.722 codec on your SIP Trunk. This setting is located under SIP Connection → Inbound in the Telnyx portal.
3. It is recommended to leave the G.711U codec enabled as well for compatibility purposes.
Please note that Twilio does not currently support HD Voice, so this configuration applies specifically to Telnyx for US customers. Let me know if you need further assistance!

06/26/2025, 6:05 PMHey there! I wanted to break down something cool about LiveKit SIP for you. It comes with awesome wideband audio codecs like G.722 and Opus right out of the box - which means you don't need to do any extra setup on LiveKit's side to use G.722. Just make sure your SIP trunk provider is set up for HD Voice, and you'll be good to go! Feel free to reach out if you want to chat more about this or have any questions. I'm always happy to help! 😊 Sources: Configuring HD Voice for SIP | LiveKit Docs | Configuring HD Voice for SIP | LiveKit Docs
