On my Windows PC, I have 3CXPhone installed in Softphone mode. If I then have 3CXPhone on my Mac open and I want to live listen into a call... when I click Listen, it answers it on my 3CXPhone for Windows and I have no way of listening in on my Mac. 3CX have said: "this is happening because an invite comes from the PBX towards your extension, and the fastest client picks up. If you turn the windows client off the request should arrive to your Mac client" I want to be able to choose which device I listen into a call on, whether that be my mobile, mac, windows machine or my desk phone. The choice should not be made for me.
