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: (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


Hi Nicolai,

Unfortunately, the Yealink DECT dongle DD10K is only compatible with Yealink SIP- T41S/T42S with FW or later, SIP-T58A with FW V83 or later and SIP T53/T53W/T54W/T57W/T58W/VP59.

Kind regards,
