We have a customer who is on a UC540, using 504G and the 500S exp module with the latest phone firmware (from 8.0.4 pack) at thier front desk.
The two users are both experiencing what they describe as the speakerphone randomly coming on unexpectedly.
This does NOT happen during a connect call, but when they put a caller on hold,take an action with another call, and hit resume. Thye are not using any headsets, just the handset. I explained that if you press RESUME while the handset is in it's cradle, you will always go to speakerphone. They still describe that they ake a call- handset up to ear, put the call on hold, take another call- handle that call (transfer, etc),and when they hit resume, the call goes on to speakerphone even with the handset still up to their ear.
Has anyone else experienced this? I suspect call handling behavior and not a bug or bad phone.
Is there a default setting to prioritze the handset over the speaker no matter what action?
Does it somehow relate to having and using the 500S module?
I cannot recreate the issue at my desk, but I have a UC520 and 7975 so it's not an accurate reproduction.
I am stumped on how to prove that it is normal behavior and they just didn't realize what they were doing ...
