How to test DTMF signals are working fine?

[dinstar]

As title suggest, How can I test if DTMF signals are working fine in my setup and no false DTMF is being received by the system.
I have tried calling on particular one number, I want to test in bulk number and also, share if there is any standard way of testing this.
Thanks

We have set up a couple of client systems to be able to do this with a survey campaign, automated reports and some custom dialplan entries before. One of them was testing 4000+ DIDs every day. The key to this is using the Dial() command 'D' option to automatically send DTMF upon Answer signal from the remote end within your custom dialplan entries,
