I am trying to get some information regarding an incoming call. I have installed the TSP client on my machine and connected to my IP Phone 7945G. I am running the simple TAPI application to get the properties of a call, such as CallerID, CalledID, etc., but not the required one.
 
An outside caller (987-456-1234) calls 800-123-4567 (example), and eventually reaches my phone (Extension 299). How can I get the 800 number to be populated in my application?
 
All I can get is CallerID (987-456-1234) and CalledID (299), but I am unable to find 800-123-4567.
 
Any help is greatly appreciated.
 
Thank you so much for your time.
