I have 2 Jabra 9470 headsets and 2 Obi1062 phones. We just moved, and everything is fine with one of the phones. However, when we set up the second phone, the hook switch is working on the Jabra headset, but there's no audio. The audio works fine with the headset on the mobile phone and "soft"/computer phone, so it's not the headset. I tried switching everything from 1 to the other to try to isolate the issue, and even did a factory reset on the phone that's having trouble. However, nothing is working. I simply can't get the audio to work on the headset. The second phone works with speaker and the handset. Is this just a hardware issue? I have a paid Extended Warranty + Service ethrough August 2020.
