Audio channel for video via phone...?


I’m trying to build a system where a user (with no headphone/speakers) can play a video to their PC but listen to the audio via a phone. I envisage a system whereby the user visits a web page, is presented with a phone number/pin. They dial the number, enter the pin and then press play on their onscreen player.

I’m thinking that we can adapt a video streamer to connect to an asterisk conference, playing the audio into the conference which contains the (only) user. Or is there a better way?

Any ideas would be gratefully appreciated. Thanks.
