As tcpdump doesn't show non-ASCII characters you cannot "read" the request.
But the Bad request answer basically confirms that the Asterisk ICE implementation has an issue with PhonerLite.

> O.K. this is a bit hard to explain for me:
> If I use PhonerLite (and I can only replicate this issue with PhonerLite, but there it happens 100% of the time!) to call asterisk (any number, and any setup, nat, no-nat, etc.) I get the warning:
> RTP Read error: Success. Hanging up
> The "Success" part of the error should be the error message. BUT Success indicates, that there actually is no error.
> So what I did was changing the code and checking if the errno is 0, ignore that line ... and it works.
> I do not get this error with the SVN for Asterisk 10, just with SVN Asterisk 11.
> So basically under some circumstances (I cannot replicate the real issue, ... even the debug log doesn't show any issues at all!)
> the errno is set to 0, instead of whatever it should be...
> Can please someone have a look at this.
> (I would be open to test anything, although my dev capabilities are limited.)
> It really is a show-stopper to me! :-(
