Here is the scenario we are experiencing with our HP 4120 Lync phones running the latest available firmware (4.0.7577.4455)
1) A User has an HP 4120 phone and is a member of a workflow/response group which is setup with attendant routing method.
2) The ringer volume is set to the minimum level by the user
3) When a single call comes in to this user, the ringer volume level works as expected
4) When two calls come in at the same time to this users phone, the ringer volume set by the user is ignored and the ringer plays at Maximum volume.
This is causing disruptions to our office environment as we are unable to reliably control the volume levels of the ringers.
There does not appear to be anything more in the settings/menus of the phones themselves. I am thinking this may be an issue with the firmware, but if anyone else has any suggestions, they would be appreciated.
Thanks!!
