I upgraded my Conference Center to CONF3_2_20 since I upgraded my IPO500 to 5.0.08 and my VoicemailPro 5.0.21 but now I get spuractic "conference not acessible" messages. Sometimes the conferences work and other times they don't even get the message "Please enter your conference ID" instead it goes straight to "Conference not acessible". Has anyone had this issue?
