Jabra problems with updating
The first step you’d want to take is to ensure that the problem is with your i Phone or i Pad and not with the Bluetooth accessory you’re trying to connect to.
Recommendation: If you are inexperienced with updating Jabra device drivers manually, we highly recommend downloading the Jabra Bluetooth Headset Driver Utility.
As we have kind of “standardized” on the Jabra UC Voice 150 Duo for the general user we first tried replacing the headset with a newer one, suspecting it was faulty. Running updates on Office, running a “repair” on Office, updating drivers directly from the manufacturer etc. Then I came to think about some Jabra software I used to run on my PC, because I was using a bluetooth headset for both my cell phone and (back then) Lync – and I was struggling to get the call control from the headset working.
