I want to understand why a playback gets cancelled.

I have an ari client which controls playback due during testing we observed some files are not played and are getting cancelled. In this particular scenario we receive a DTMF so we stop current playback (which works fine) but the next audio file is getting cancelled for which we don’t issue stop command.

Any help or pointers is greatly appreciated.
