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

Just did the test. Your code works, and the DTMF are played right after the callee answers the phone.

p and w are supported as well, looks like the implementation is conform to the RFC 3601.

  • Thank you . I was testing it in emulator and emulator wasnt outputting any sound tone for the dtmf. Thats why i was confused weather dtmf tone is being sent or not . Will now test it on device. Thanks anyway. – Shofiqul Alam Dec 30 '12 at 08:34
