We have an Iwatsu phone system and use the VMI Editor to manipulate voicemail boxes. The box that had the software loaded crashed and we are trying to set it up on a new box. The box that crashed was WinXp and we are going to a Win7 machine. We are not able to establish a connection to the phone system now. We are using the same profile from before and have even tried to create a new profile, but it fails to connect. I heard someplace that you had to change some registry setting for the network card's MTU settings, but not sure if this is the case. A tech in a remote location has a Win7 laptop and is running this successfully without error? Please Help.
