I have recently installed UC320W with 2 FXO and 1 FXS line using Key system. I have used the Line out to connect the Paging. The issue is that the customer likes to have all their phones ring and paging on the external paging simultaneously when he gets a call on any line. Has anyone got a workable solution? I saw an old discussion on this subject for UC560, but that discussion is not yet answered.
Thanks for a quick resolution.
