[asterisk-app-dev] Asterisk AMD Application

[Sotiris Gkanouris]

Hello Wolfgang,

The thing about playing something during the AMD is that it would “interfere" with the response of the called person. If there is a human in the other line it would listen to the media while not speaking thus resulting to wrong decisions from the AMD. 
To answer your question, as far as I know it’s not possible to play a media file during the AMD though.

In this time for normal - the called person does hear nothing. My Customer does think that it would be great to be able to play some short music / announcement in this process - to get better results in the Answering machine detection (i don't think so - but hey - lets try).

I assume i have to use some sort of ast_stream_file on the channel to the called person - but i think this function will block. I would need a ast_start_stream_file - and a ast_stop_stream_file function for this - is something like this available ?
