I am new to this forum, and I need your help.
I have an EC25J and want to use voice call function.
Regarding phone calls, it is possible to make (atd) and receive (ata) calls.
However, no audio is received from either end via USB Audio.
The revision of this device is EC25JFAR06A05M4G.
Do I need to update the firmware?
Thank you very much for your supports.
Recently, I received the new firmware for EC25J. The revision is EC25JFAR06A06M4G_01.008.01.008. USB Audio of this firmware works. We get all audio via USB Audio.
