The staff want to have one voicemail which anyone can access from their handset. This needs to be the default. I am aware that they can use keystrokes to access another user's voicemail but in this instance I want the default to be the one shared voicemail. This was possible using the Linksys SPA9000 which I have just decommissioned. Handsets are Linksys SPA941. Is this possible?
