I'm running LYNC 2013 and on the client installs it isn't possible to permanently disable the secondary ringer functionality, the option can be unchecked and works OK until the system is logged out, when logging back in it's re-enabled.
There is mention of this issue in kb2770885 which is to be resolved in a later release but the kb is a few years old now and I have the latest version and issue persists.
Does anyone know if there is a registry change or patch/update that needs to be applied to get round this issue?
Thanks
