Hi All,

I am having Call Manager 7.1. I am trying to send DTMF signals after the call is connected and then receive the signal ..and then depeding upon the signal recieved, I have to proceed with further tasks. But currently I am stuck as I am not able to extend the BasicMediaService class. Its showing me an error. Can you please help. I am atttaching the code snippet.
