T42U with DD10K

[ELW-Technik]

Hello,

I like to connect the Yealink T42U with an DD10K USB-DECT Dongle.

Unfortunately the DD10K isn´t recognized from the T42U sip phone.

It doesn´t matter which USB-port on the backside of the phone is used.

I restarted the phone but nothing changed.

Firmware T42U: 108.86.0.70 (2022-08-30)

Is there a setting in the web interface of the ip phone where the dect dongle or the usb interface can be selected and edited?

Thanks in advance.

Kind regards

Nicolai
