Does anyone have any experience with software that will compile multiple call manager clusters which are integrated to active directory via one customized Corporate Directory? So all phones no matter what cluster they are homed into refer to the same Corporate Directory ASP which could then optimally be broken down into searchable geographic regions depending on OU properties. I could use the SDK and create my own if they were using DC Directory. We have been using Aptigen in the past but that company no longer exists so I am looking for alternatives.
