I'm sorry, I don't know which board to ask this question in. If I posted it in the wrong one, pls kindly move it to the right board. Thanks in advance.
There's a Cisco 7391g phone https://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7931g/6_0/english/user/guide/7931ug.pdf
and this headset https://www.amazon.ca/Cisco-Headset-Landline-Microphone-Phone/dp/B07D4FV3RR/ref=sr_1_3?keywords=7391g+mkj+headset&qid=1698791038&sr=8-3
that the purchasing dept has bought twice for the principal user of the phone. The stereo headset audio is strong from the left and right earpieces but the headset microphone never picks up any sounds. On the first headset, I thought the mic was defective but as the second headset had the exact same issue, I started to think there's some config I've overlooked. The headset link says step 3 is to toggle a physical headset button (which the 7391g does not have). The 7391g manual says that button 23 of the 24 programmable buttons is the headset toggle yet pressing that does not light up the buttons or toggle the headset. In fact, the phone menus are stripped down to simply parking or transferring calls. Try as you might, you couldn't get the navigation buttons or any combination with the other buttons to summon preferences/settings. I think there is some policy or restriction set in place that's limiting the available options/functions; is there a key combination that I can press to bypass/circumvent the limiting policy, and thereby restore all features or would I have to contact the contractor/installer?
