I have a samsung a920 that i'am using with a jabra jx10 bluetooh headset but I'am having a problem. When I try to answer my call waiting it won't let me do it from the headset it end the call I'am on. I was using a plantronics BT before this and it let me answer call waiting no problem them it started doing what the jabra is doing no now. Could this be an issue with my phone's setting and not my BT headset? I really need help on this guys thanks.
