So "don't work" still means "no audio" and "sip is ok", clear...

RTP packets are lost somewhere on the way:

You can check where RTP packets are lost - between FS and siptraffic, or between FS and your SIP Client.

1.Install "ngrep" if you don't have it yet (on Ubuntu: apt-get install ngrep)
2.Run it: "ngrep port 5080"
3.Start a call and after few ngrep's messages, stop ngrep using Ctrl+C
4.Find the first INVITE line from your FS to siptraffic, it will contain your IP and port at the following lines:
c=IN IP4 ****!!!YOUR-EC-IP!!!*****..t=0 0..m=audio ****!!!YOUR-RTP-PORT!!!**** RTP/AVP
5.Open new terminal window, and run "ngrep port ****!!!YOUR-RTP-PORT!!!****"
6. Wait 5 seconds
7. Stop ngrep using Ctrl+C
8. Hangup

Now on the second terminal you should see a lot of line pairs like:
YOUR-EC-IP -> SIPTRAFFIC-IP
SIPTRAFFIC-IP -> YOUR-EC-IP

If you see only one of the directions (e.g. only YOUR-EC-IP -> SIPTRAFFIC-IP), then some problem is between FS and Siptraffic.

If you see both directions then problem is not here and most probably on the way from FS to your SIP Client or somewhere else (inside FS?)
If so, try to investigate this part using port 5060 (same way as 5080).

This analysis will narrow the problem a bit...

This provider does work on another box which is not natted as ec2.
Most puzzling here though is why call originaion via api even not
going via siptraffic still gets no audio.
