Any ideas why voice going from web app (lk sdk) through livekit cloud through telephony sounds bad but it's great on a recording? Can it be some codecs misconfiguration or something else? Anyone had simillar issues? SIP trunk codex is g711a. I don't see g711a anywhere in the livekit dashboard settings.
In case anyone has this issue, it was DTX. Turning it off fixed it. It's still not ideal but much better.

Hello Mike - can you please tell me where I can find this DTX setting? Is it on Twilio or Livekit?
e
It's in room's options when you create it on frontend, it changes how frontend encodes opus
If you use react components, it's 
options
prop on 
LiveKitRoom
component,
Copy code
options: {
  publishDefaults: {
    dtx: false
  }
}

Thanks a lot. I have also seen the audio is not great in telephony settings too. The elevenlabs audio gets mushed up when I take a call on LiveKit via agent sdk vs elevenlabs audio directly on their website

Unless your telephony provider supports G.722, it won't ever sound simillar

Would it be possible to elaborate a little more on this Mike pls? I am using Twilio and TCN dialers which both support PCMA 8KHz audio that LiveKit also supports.
e
Twilio doesn't support HD voice from what I know
I'm not familiar with TCN
G.722 is 16KHz

Ack - thanks for explaining this

My pleasure
