Its not exactly that. I expected an FXS port would by itself generate a busy tone after a call (initiated or not by this port) is terminated by the other end. Doing this permit the phone connected to this port to detect the end of communication and hang up automatically. That said, I guess the dialplan example would work when the FXS port is the A leg, but what should I do when the FXS port is the B leg ?

I googled through but could not find anything relevant. So then with my FXS port, do I have to, when a call is over, bridge the channel (which is either A or B leg depending on the cases) to an extension with for instance <action application="playback" data="tone_stream://%(500,500,440)"/> if you're just trying to manually send out that tone then yes, you can just add the line in your dialplan. You can then hangup after playing the tone. The other end will have to decide what to do on its own. -MC
