</div></div>Yes, it's disappointing that Fring doesn't release the media. I tried<br>
it a few times, but the latency was unacceptable since the hairpin<br>
apparently has very long "legs" from a millisecond-delay perspective.<br>
<br>
I had it working once, but now for some reason I get authentication<br>
errors (repeated REGISTERs and they don't seem to see my replies) and<br>
I don't really have the time to work it out. Anyone having similar<br>
problems or is this my local problem?<br></blockquote><div><br></div><div>I've just had a look, and can confirm that it is working here... even quite a while after the fring client has been closed :/</div><div><br></div>
