I checked the document you provided. Thanks.
I understand better now. According to the screenshot, Yealink phones do only support narrowband 8kHz and widenabd 16kHz, not super-wideband and fullband. The codec itself would, but not on Yealink IP phones.
Only on decoding the T23G supports super-wideband, but that is of no effect cause it's not happening on encoding.
I am looking for an super-wideband codec to increase quality, but so far Polycom and Digium are the only ones providing G722.1c (siren 14), which is 24kHz super-wideband (or ultra-wideband). Hopefully Yealink can catch up to the competition here, cause it really is another great leap compared to G722. Try a Polycom phone and you will be impressed.

Another question:
The document says "Opus sample rate is only configurable on SIP-T48S/T46S/T42S/T41S/T27G IP phones" from the GUI.
How do I configure Opus sample rate on T23G phones (either 8kHz or 16kHz)?
