Hi team, does Livekit supports AMR-WB for HD Voice calls on telnyx?

Not AMR but HD voice does work. I believe that is G722

We have HD Voice enabled on our Telnyx numbers, and we cant make outbound calls to mobile carriers without degraded audio. This is the response we got from Telnyx: "The incoming codec was G722 and outgoing to the receiving carrier for 1284 was AMR-WB. Limitations are on all sides: Livekit only allows G722 as a wideband codec Receiving carrier only allows AMR-WB for HD Voice calls Telnyx had to transcode but G722 -> AMR-WB are highly prone to artifacts" Here are some of the audio samples with bad audio when we enable HD Voice.
is there any other workaround other than disabling HD Voice to have high quality audio ?
