playback(tone_stream://%(1500, 3500, 440.0, 0.0);loops=100) to the channel.
This will play a ring-tone (swedish) and loop through it 100 times.. When I
want to stop this tone I send the break command, and directly after this a new
playback command. Maybe 1 time in 100 tries the tone_stream doesn&#8217;t stop
playing. I think this is becuase how break works. From what I understand from
the source it just sets the CF_BREAK flag on the channel, and then the playback
application will detect this and stop the playback. However, when I send a new
playback command immediately after break it will reset the CF_BREAK-flag again,
to make sure it won&#8217;t cause any problems for the new playback. So if the
original playback (tone_stream) didn&#8217;t check the flag before it was
reset, it won&#8217;t known that it was supposed to stop playing.</span><o:p></o:p></p>
