company switched to these. If set up with Cisco Jabber, the buttons on the phone don't work, you can only place calls through Jabber app. Does not feel like you have a real office phone where you can do standard functions like transferring, conference calling, etc. All in all, not an acceptable replacement for a office phone.

Whilst this handset works fine with Skype, I've found it impossible to use with other applications e.g. Zoom as the microphone remains muted until the green button is pressed and then the dialling tone drowns out the call. The phone also cancels the "call" after a brief period.

My company purchased these phones because they are "Optimized for Lync" However, sound has never worked. Tried ALL my USB ports, re-installed, no luck
