T58A Teams Edition and EXP50

[ANafziger]

I have a shiny new Teams Edition T58A, upgraded to the latest firmware (58.15.0.45). I also have a new EXP50.

When I reboot the T58A, the EXP50 hangs on "Welcome, Loading....". If I reconnect the USB, it'll boot and load in about 3 secs.

The phone status (Web UI) shows that it is connected, and displays the hardware and firmware revs:
Firmware Version 1.0.1.5
Hardware Version 75.1.0.0.0.0.9.0

However, that is where the magic ends. I have no way of configuring the EXP50. Long press on a button doesn't do anything, and there are no options in the WebUI (or on the phone UI) for configuring the EXP50.

Is the EXP50 not compatible with the Teams Edition of the T58A? Or do I need to try and upload some config file to the T58A with the DSS options?

How can I configure the EXP50 on the T58A Teams Edition?

Thanks,
A.

Dear Customer,

Thank you very much for your support to Yealink.
Teams phone currently not support EXP50, we consider the implementation of expansion feature in the feature release after Teams APP supports contact feature.

Thanks for your time.
