Echo improvement on UC20-G

Hi, I got a echo on calling on UC20-G (hearing my self on my phone called to UC20-G)

Command used on audio initial
AT+QAUDMOD=0
AT+QDAI=2
AT+QSIDET=0
AT+CLVL= 1
AT+QMIC=1,21505,7567
AT+CRSL=3

What should adjust or any command to help with?

Hi @MangMuang
Are you using a headset or a cell phone or a handset? Different sound devices have different parameters to adjust to control echo cancellation. Can you give me your email address? I can send you the audio guide for your reference.
