We are thinking of upgrading our Call Manager to version 5.0 I have contacted Cisco about this issue but there seems to be a contradiction between what the tech told me and what is on their website. I need to run CM on a Gateway 9515 but the website says that it will only run on IBM's or HP's. However, the tech said that it should run on the Gateway. It doesn't make much sense to me that a software package would run on one vendors equipment and not another. The specs of the 9515 are >= what Cisco recomneds. Has anyone had any trouble running CM on a non HP/IBM server?
