How to set an incoming phone call listener in c# application with phone connected to pc via bluetooth?

Question

I am using 32feet.net library to achieve bluetooth connectivity of my c# application to a mobile phone. Up until now i have achieved Discovery, Pairing, and Dialing a phone call. Dialing is being done by using AT command to the phone.

Some useful links about above mentioned activities are

I am looking for help in receiving incoming phone call through my application. Now from different forums all i have come to know that we can accept an incoming phone call by using "ATA" command.

An incoming call will send a "RING" notification to the application, but i dont know how to be able to read the RING notification or make my phone send a RING Notification to my application.

Appreciate your help.
