I am glad Teams phones now support sidecars; that's a needed feature for receptionists and call centers. However, based on my experience testing the Yealink MP56 and EXP50 module, I recommend that others defer purchasing sidecars for a bit. As noted in the post, the update supporting sidecars is still in beta and it contains lots of bugs, including: (i) the sidecar buttons are populated in the order contacts are added to the speed dial list rather than alphabetical, which is a problem if you need to add someone later; and (ii) when you answer the phone, the names on the sidecar screen disappear and the screen displays "sign into your account," which prevents the user from using the buttons to transfer calls. Based on the http://support.yealink.com/previewPdf?file=http%3A%2F%2Fsupport.yealink.com%2Fforward2download%3Fpath%3DZIjHOJbWuW%2FDFrGTLnGyprkfRlGTqdFMFNIUGiSGdy66kpU2kXJZlPxeQNxUrzdGNKG4bEb0wModnyEHEtzAjEh6myOsNXo%2FcPXMl9b%2F3r4XYTRqZVVUVVTSZky5XBEK%2Fc5LIwqxx4Y8gTZXIFI8ZplusSymbolEneoiUgSplusSymbolBfgG7LyOylBM%3D regarding the latest firmware update, the latter issue is a known bug and supposedly will be fixed when MS releases the next update to the Teams app (1449/1.0.94.2020121001). Although it doesn't work great at the moment, the EXP50 looks cool and it's nice to be able to see the status of up to 60 users at a glance.
KruthikaPonnusamy, do you happen to know when the Teams app for the phones will be updated and pushed to the Teams Admin Center? Is there some way to manually download and install the update in the meantime?
