Cisco 7961 Headsets on UC520 System Not Working, Speakerphone Works Fine
Posted on 2016-09-22
I'm working with a Cisco UC520 system. The phones are mostly 7961 and 7961GE. My problem is that a few of them have the headsets not always working. However, the speakerphones works fine.
They previously worked without incident. All that was done was to change the associated extensions. Originally 3 had this issue. One phone suddenly started working out of the blue. I know these phones are known to have hardware issues, but is there anything that can be checked from a settings or configuration aspect?
