When the phone is in a ringing state, AGGSmart will show the incoming call tab. Once the call is connected, you can click the 'Search' button to open the callers details. If it cannot find the number, it will return a blank screen.Prior to installation, contact AGGSmart to find out the Customer ID, and give them a list of the extension numbers which you'd like the phone integration to be enabled on.  

If the integration supports caching, please note that cached integrations support up to 30,000 contacts. The live mode method would need to be used for larger directories. Performance will then be determined by a number of additional factors including network speed and application API specification.
