Have a 406 v2 on 3.2.69 with VM Pro. The voicemail Pro is actually running on customers server 2003 SP2. Has been running fine for 4 plus years. Yesterday licenses come up as invalid. Voicemail will run for 2 hours and stop. Under services key server and both vmail services are started. We have restarted all services,the server and also the PBX numerous times. I even uninstalled the voicemail pro and reinstalled it today. IT person says no updates on the server have occurred. USB shows rainbow driver as good. Customer has unplugged the USB dongle and reinstalled as well. Ran a voicemail debug as well. Any suggestions???
