Yealink V82 Firmware, Headset Problems

[Slyoder]

We updated a few Yealink T48s phones to the v66.82 firmware and started getting complaints about users being unable to answer calls using the button on their headsets. Mostly Plantronics headsets connected with EHS-36s. We rolled back to v81 firmware and everything started working again. I did not have time to do a lot of troubleshooting right then. Has anyone else experienced similar problems?

Hello @Slyoder

We have contacted Yealink support regarding this and Yealink is trying to reproduce the issue. So far they have tested C054, CS530 and Voyager legend CS but they were unable to reproduce the issue.
Please feel free to contact Yealink support directly so they can assist you to identify the issue.

Thank-you for the response YiannisH_3CX, I hope to dig a little deeper into his issue first of the week.
One question, are you aware of any issues with upgrading to 15.5 Update 2 while still on the V81 firmware?

Please note that SP2 has been tested with the V.82 so i could not really tell you if there are any issues with SP2 and V.81 firmware. What i can tell you is that we did not have any reports for such issues yet but it is always recommended to run the supported firmware
