Team, I was able to get the lab working, and I was able to reproduce the issue. To reiterate: the issue Agero is reporting is that when you are on a call the enter button on your keyboard mutes the call. This is absolutely true. More detail provided below, and yes this is something that Avaya developers are going to have to fix. This would be a request for a product feature enhancement; it is not a ticket with Avaya support. Read: do not approve charges with Avaya support. Here are the details that you could pass along to the Avaya Workplace product house if you wanted this to work in a different fashion: Behavior: when you are on an active call in Avaya Workplace the enter button on your keyboard mutes the call. Able to reproduce in recent version of Workplace 3.38.1.10 Why does it do this: You can clearly see in this screenshot "Exhibit A" that the "mute" button is "highlighted" (indicated by a dotted outline) upon answering a call. Therefor the "enter" button on the keyboard "activates" this highlighted section, thus muting the call. I suspect this was intentional, so that users can easily interact with the application without having to use the mouse. For example you can press tab, it will move the highlight over to the "end call" icon, and then hitting enter ends the call. Issue: Agent Users at CompanyA are accidentally hitting the enter button and muting their call, thus resulting in possible call avoidance Desired feature enhancement: make the "default highlighted item" configurable. Or add a configuration option that disables all keyboard interaction with the call control buttons. See Exhibit A attached
