We're having issues with Plantronics's CS50 headsets and 7960 phones. Users are having choppy voice or even audio cut-off during a conversation, this happens when both the caller and the called one are talking simultaneously.
One of the users seems to be having more problems than the others, we changed the phone, the headsets, the sw port, we checked the wiring, nothing fixed it. We even exchanged device, headset with another user who's setup is exactly the same, but in the office just next to him, same issue again with the other one's gear. So we tought it was an "environment" thing, like something is interfering in HIS office only.
But since this morning, we have the issue with 3 users, 2 of them are physically next to each other and the third one is physically apart, so not on the same sw, but still in the same building. So, I'm confused and don't know were to look at.
We did the Plantronics procedure to reset the headset, did the tuning, reset the phones, etc. but nothing seems to fix the problem, so now the users are using their handset...
Any help would be very appreciated!
