Hello,
I am following the tutorial in [color=#FF0000]https://wiki.asterisk.org/wiki/display/AST/Introduction+to+ARI+and+Channels[/color] and have downloaded and installed [color=#FF0000]https://github.com/asterisk/ari-py[/color] in my system. I am able to interact with ARI using [color=#FF0000]wscat[/color] per [color=#FF0000]https://wiki.asterisk.org/wiki/display/AST/Getting+Started+with+ARI[/color] and I see channel creation/state change/deletion notifications that in the [color=#FF0000]wscat[/color] log. However, when I run [color=#FF0000]channel-dump.py[/color] in another terminal in the same machine (connecting to [color=#FF0000]http://localhost:8088[/color] like the tutorial), I do not see the channel creation, deletion and state modification messages. The only message I see are either [color=#FF0000]No channels currently 
[/color] or, if I have a current channel running, and then I fire up [color=#FF0000]channel-dump.py[/color], I see the current channel information. However, I do not see the notification when I hang up the same call. I think this is due to the fact that the event callbacks in [color=#FF0000]ari-py[/color], specifically the lines:
client.on_channel_event('StasisStart', stasis_start_cb)
client.on_channel_event('StasisEnd', stasis_end_cb)
don’t seem to work.
Any ideas on how to fix this is appreciated.
