Recently one of my friend asked me how to forward calls using the USSD commands. This link describes how to forward calls using USSD codes. I tried a lot using my previous article code but ended up with no success. The USSD command are sending successfully but always the result is “UNKNOWN APPLICATION”. Then I decided to work on a sample using the TAPI API lineForward.
The lineForward API is used to programatically forward calls. The syntax of the API is defined as:

The first parameter is the handle to the line (Cellular Line), second a boolean value indicating all originating addresses of the line or a single address of the line. Third is the address id of the line. Fourth is a po
