[Asterisk-Users] Send tone to src on supervision

[Ed Greenberg]

I've been asked to configure Asterisk to send a tone back to the caller 
when the call is answered, to indicate answer supervision.

What can I do in the dialplan to accomplish this.

If I use the M() syntax on the dial command, I send the tone forward to the 
callee.

THanks,
