3cx recently rolled out their version 18 update 6 which among other things has disabled the call button on the side of the headset. Calls can only be answered by on-screen action. Many users have reported issues but 3cx insists its a hardware issue/poly Hub problem and not on their end. Jabra and Poly integration is no longer an option but Universal Headset is the lone choice. Not sure what to do at this point.
