no audio when using mobile connection #143

What steps will reproduce the problem?
1. setup a mobile broadband internet connection
2. connect with Chrome to https://151.13.14.14/click2call (it's a test page you 
can do it)
3. press any button to call

What is the expected output? What do you see instead?
When I use a home ADSL internet connection everything is fine, it works!
When I use a 3G internet connection: no audio at all.
Sipml5 and Asterisk consoles are basically the same in both cases.
Watching server pcaps stun seems to fail, but I don't understand why.
Maybe because 3G provider connects my host with an extra nat?
Same thing happens with android mobile device: by adsl (wifi) it works, by 3G no
Same thing happens with windows7 pc: by adsl it works, by 3G no

Scenario:
ok:
[*&webrtc on same host] <-nat 1-1 to public ip-> internet <-ADSL-> Chrome
ko:
[*&webrtc on same host] <-nat 1-1 to public ip-> internet <-3G-> Chrome

Tested 3G connections from different mobile operators with same results.

CentOS server 6.0
Asterisk 11.5.1
webrtc2sip 2.6.0
sipml5 1.3.203
Chrome 31.0.1650.57
Ubuntu client 11.04

Grazie
