i just tried tryit app with chrome 26 and calls worked for me.  there
was considerable delay (about 10 sec) before the called browser showed
the call coming in, but once it did, i was able to answer the call and
see video flying both ways.  i didn't hear any audio, which may be due
to audio settings of the browser.

use wireshark to see what is going on on the wire.

i noticed that tryit app uses normal sip tcp port 5060. i didn't even
have websocket.so loaded in my proxy when i did the test.  perhaps it
falls back to sip over tcp if sip over websocket transport is not
supported?
