I'm running UCME 7.1 and I would like to integrate the contacts in my client management system into the local directory of the phones. Is this possible? If so, what format should the contacts be in?
You can put anything you can cram into Cisco flavor of XML phone code. Cisco's SDK for the phone defines the Directory XML that the phone will read. If you can write a php script or an asp page that will generate that code, you can put anything you want as a phone directory.
