I recently downloaded the CISCO Jabber 12.8 and started using, however, I am not able to get any voice calls to my USB Headset even when I am making the call from the software. All calls goes to the desk phone.
I have a IP Phone 7942 connected on my desk and a USB Headset device connected to my laptop. In Jabber Audio settings I can see the USB headset and I could play sounds through it and also Mic is seen by Jabber. However, the Call Device list has only the desk phone option. I understand it should show something like "Calls through Computer" to be get the the calls through my headset.
