mod_dptools: flush dtmf
Table of Contents (click to expand)
Flushes DTMFs received on a channel. Useful in cases where callers may have entered extra digits in one dialog and you want to flush them out before sending them into another dialog. (See mod_dptools: play_and_get_digits).
If you have issues with mysterious DTMFs being entered in your dialogs then try adding '''flush_dtmf''' before the dialog and see if that helps.
