<div dir="ltr"><div>probably if the UA's are on the same network, when you send the package the package is going with the external ip on the SDP , when the call is stablished probably you router is not allowing to open the second lag because the UA's are trying to stablish from inside using the outside ip addressl, so when you go through rtpproxy this not happen both sides use the opensips (rtpproxy) ip address to sdp.<br>
<br></div>If my logic is not correct please somebody let me know.<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/10/4 Rodrigo Ferreira <span dir="ltr"><<a href="mailto:rsferreira08@gmail.com" target="_blank">rsferreira08@gmail.com</a>></span><br>

<div dir="ltr">well, probably you softphone/ip phone, is using some kind of stun or other kind of nat features, so, nothing come to be detected, this can happen, so, if you will be ever using nat, you can force the rtpproxy without nat detection, this will solve your problem, if you read the documentation (<a href="http://www.opensips.org/html/docs/modules/1.9.x/nathelper.html#id292854" target="_blank">http://www.opensips.org/html/docs/modules/1.9.x/nathelper.html#id292854</a> ) you can see that this test are made over rfc1918 or different ip address from via and signalling <br>
<br>The problem is probably the fact that when the call is stablished, the media cannot traverse, you have the correct ip information on sdp but the router does not permit the session to be opened, so, do a test forcing the use of rtpproxy without the nat detection, just force all trafic throught rtpproxy<br>

<div dir="ltr">Hi guys,<div><br></div><div>After a long time without using Opensips (almost a year) I tried to install the opensips 1.10 and everything went well BUT when I make a call, there's no audio, I know that is something because of NAT, but I have the nathelper and rtpproxy configuration on my opensips.cfg.</div>
<div><br></div><div>There's anything else that I could take a look at?</div><div><br></div><div>Thanks<br clear="all"><div><div dir="ltr"><div><br></div><div><br></div>Atenciosamente.<div>Eng.° Rodrigo Ferreira</div>
