We are getting ready to cut over our existing phone system to 3CX. We already have 3CX running and configured. The last thing I need working before we cut over is our BT headsets with the v15 softphone. We have about 20 users with Plantronics Voyager Legend headsets. I get audio to pass through just fine, but call control does not work with the headsets. I've tried a combination of using the built-in BT on some computers and BT dongles (Tripplite). I've tried installing various versions of Plantronics Hub software (the earliest I can find online is 3.7.5, even though the filename is 3.7.1). I could not find Platronics Spoke as mentioned in some threads. Has anyone successfully gotten these headsets to work correctly with the v15 client? Thanks!
