I don't know for sure but I suspect this doesn't return while there is  
early media, therefore you don't actually get the ringing.

That is my understanding, yes.

Can you experiment with this in a regular dialplan outside of js? Try  
creating a simple dp entry that does these apps:
sleep (20 seconds or so)

Say you create the above dp entry as extension 2500. Do an originate  
at the CLI and examine the results:

originate sofia/gateway/westhawk/0663 2500

This should call the URL and as soon as there is early media  
(hopefully ringing) it will put the originated call leg into ext 2500  
which will pre answer the call (so you can "hear" the early media),  
execute the record session, do an info dump for good measure, sleep  
for a while and then hang up. You should then be able to listen to the  
sound file and if all goes well you will hear ringing prior to the far  
end answering.

The results of this test will help you decide where to go next. :)
