But One Question is in my mind if the Palm Reference provides telephony manager Library then why is it not available
It's historical. Handspring did most of their Treo work before these APIs were well defined by PalmSource, and since the Treos are all derived from the original work done by Handspring, they have stuck with their own implementation instead of taking the generic telephony framework. -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
