We installed a Mitel wireless headset on a 5340 and the user complains that every 30 seconds or so she hears a beep in the headset while conferenced in with another user.
Battery is fine, she is very close to her phone and it is not a camp on.

Is there a conference warning tone and if so were do you set it?

Thanks in advance.
