Hello everyone!
I am working as a Helpdesk at a company, and the users of the network have a Cisco Unified IP phone 6921 each one of them.
Some of them are using Plantronics' HW251/A headset, and they've been using it for a while now, but since last week all of the headsets stopped working...
The headsets are connected to the phones using a U10P-S cable, but none of them are working no matter which phone I plug them into. I also tried to plug them in different phones, using new cables, using a new headset... but any of these seem to be the solution...
Please I need help, these headsets were expensive and I don't want to have to buy new ones... Could it be something wrong with the phones themselves?
I also noticed that when hitting the headset button to check if I can hear any signal (which I don't), when I turn off the headset button I do hear like a "cut" noise, but anything else... Its frustrating because I know these headsets are functional, but I can't figure out how to make them work!
Thank you :)

Has the call manager or 6921 phone firmware been upgraded recently?
A new firmware could have a bug with the headsets, if they have recently been upgraded.
Trouble with all 6921 phones started at the same time, sounds like a possible firmware issue.
Our callmanager was recently upgraded, which upgraded the phone firmware, which cuased our 8945 phones to get stuck in the upgrade process. Phones were attempting to upgrade from 9-3-2 to 9-4 and it failed. We had to upgrade them to 9-3-4-17, then to 9-4.

Hello Aman
For the symptoms, I dont think I burned out the headset jack, because I tried a spare U10P-S cable I had from previous orders and it worked miraculously...
Apparently all of the new cables I ordered are faulty, so I should try to get a refund for them or whatever... Thank you for taking your time writing a response, I will mark your answer as Correct since the symptoms described are similar to what happened to me.
Thank you

Finally I found a cable that was working... Apparently ALL OF THE U10P-S CABLES I ordered were faulty... I found a spare one in one of the boxes in the server room and tried it, guess what? SOLVED hahaha
Thank you all for your time, will keep in mind your replies for future issues :)
