I know using phonecalltask we can make a call programmetically by filling the phonenumber field .
A sample code may be
PhoneCallTask phn = new PhoneCallTask();
phn.PhoneNumber = "9807689,657";
phn.show ();
But my question is,is it possible to send dtmf right at the point when we are initiating calls ?
like in android and iphone we can send dtmf by dividing the number with ",". EX: 9876543,123
Is it also possible in windows phone? if possible is windows phone uses the same format to separate dtmf number or they use other tag other than "," ?
How to call programatically using p and w commands,and most predominantly the dtmf sound must send automatically after call
