Hi.

It's hard to tell exactly what's going wrong here, but Asterisk is 
responding to the HTTP request with a 404. This likely means that 
Asterisk can't find the recording in question. Although it is also 
possible that the URI being passed by python to Asterisk does not 
"resolve" as expected. If you look at the HTTP traffic, you may be able 
to tell more clearly why the 404 is being sent.

It's certainly possible there's a bug in Asterisk, but I would be more 
willing to bet that there's some sort of error in the python example. 
Although, like you, I don't immediately see the problem in the python code.
