I am planning to upgrade my IPO to 4.x version. Now i am using 3.2. The reason is that i want to have all my IPO applications on same version ( Phone manager, VM and Office version) I have IPO 406 with Phone 30 module. Using 1 BRI card. Phones are 8 digital and 20 analog. Did anybody ever noticed any problems with 4.x version? I would be very grateful for you answers.
Best regards, Marko
