I am trying to upgrade the CM to 3.1(2c) but after the installation, when the program asks if I want the system to reboot and I answer yes, the system does not reboot. I have to power cycle it and of course it remains with the old version. I wait for about 20 minutes before I do it.Isn't it enough? I have performed the upgrade to other -smaller- IP telephony networks and I did not have such problems. What can be wrong? I am talking for an IP telephony network of one cluster with two CMs (7835) and about 100 IP phones (and users plus device profiles...). Thanks,
