<div dir="ltr">After struggling with one way audio issues as a result of STUN binding errors on both the Asterisk side and the Chrome side, we've decided to just simply go with a TURN relay for RTP packets until the issues are resolved. <div>
<br></div><div>I configured rtp.conf so that all of the STUN related entries are commented out, and I use the following TURN configuration instead:</div><div><br></div><div><br></div><div><div>turnaddr=<a href="http://numb.viagenie.ca:3478">numb.viagenie.ca:3478</a></div>
<div>;</div><div>; Username used to authenticate with TURN relay server.</div><div>turnusername=myusername%<a href="http://40gmail.com">40gmail.com</a></div><div>;</div><div>; Password used to authenticate with TURN relay server.</div>
<div>turnpassword=p@ssw0rd</div><div><br></div><div><br></div><div style>I also use the same configuration on the client side. When running a tcpdump, I see that there is traffic to/from the TURN relay:</div><div style>
<br>
</div><div style><div>10.0.1.18.53875 > blues.viagenie.ca.nat-stun-port: UDP, length 20</div><div> blues.viagenie.ca.nat-stun-port > 10.0.1.18.53875: UDP, length 56</div><div> 10.0.1.18.51435 > blues.viagenie.ca.nat-stun-port: UDP, length 28</div>
<div> blues.viagenie.ca.nat-stun-port > 10.0.1.18.51435: UDP, length 100</div><div> 10.0.1.18.51435 > blues.viagenie.ca.nat-stun-port: UDP, length 144</div><div> 10.0.1.18.51435 > blues.viagenie.ca.nat-stun-port: UDP, length 144</div>
<div> blues.viagenie.ca.nat-stun-port > 10.0.1.18.51435: UDP, length 100</div><div><br></div><div><br></div><div style>But it's dead silent when doing a tcpdump on the Asterisk server side.</div><div style><br>
</div>
<div style>The candidates on both sides don't contain relay candidates. Oddly, the client side still has srflx candidates, suggesting STUN is still at work, but the Asterisk side only contains host candidates. </div>
<div style><br></div><div style>Is TURN fully enabled in Asterisk 11? If so, how does one enable it and make it the priority?</div><div style><br></div><div style>Thank you,</div></div><div><br></div>-- <br>James Mortensen<br>
