Firstly the application call at one number representing the voice server (ie: 0033333355555). After that the server ask the caller to enter the final destination phone number (ie: 0033444444444) and by this procedure we could join national and international destinations So can i make DTMF calls and how to implement using pjsip? Please provide me any solution of it Thanks in Advance Vinay
