Sounds like an NAT problem. You have two connections set up for a call - one for the signalling and one for the media. It's common that behind NAT you can have SIP working but RTP broken.<br><br>Off the top of my head there's a few possible reasons:<br>
- The router is too dumb to spot the SIP and automatically open the RTP ports: forwarding those manually may help resolve that.<br>- The router has a SIP ALG that tries to correct the IPs sent through SIP and actually breaks things even worse: try disabling that feature.<br>
- Freeswitch doesn't know the external IP address and will send the internal IP in the SDP, so the other host doesn't know where to send RTP to: try using STUN, or setting ext-sip-ip and ext-rtp-ip on the sip profile.<br>
<br>DMZ might help work around any of the above without actually solving your real problem.<br><br>-Steve<br><br><br><div class="gmail_quote">On 28 January 2011 22:31, Joao Leme <span dir="ltr"><<a href="mailto:joaocarlosleme@gmail.com">joaocarlosleme@gmail.com</a>></span> wrote:<br>

I had the firewall set up according to the wiki on "<a href="http://wiki.freeswitch.org/wiki/Firewall" target="_blank">http://wiki.freeswitch.org/wiki/Firewall</a>" and other than that I changed the "domain" on vars.xml to my external ip of the router, it created an ALIAS so that I can use as the "Domain" on X-lite to log on. So I had the internal profile mod_sofia@192.168.X.XX:5060 and the Alias 76.XXX.XX.XX, that was before and I was able to LogIn, make calls but NO SOUND. NOW once I forwarded all the port through DMZ, this particular router 2701HG-B Gateway (Att) required me to change my (freeSwitch running computer) static ipv4 (192.XXX.X.XX) to DHCP and then assigned me the external IP (76.XXX.XX.XX) as my a Ipv4. Now the internal profile (sofia status) is mod_sofia@76.XXX.XX.XX:5060 and I'm not using the ALIAS.</div>
<div><br></div><div>SO...I was wondering...it wasn't working before because 1) A Firewall configuration missing? 2) A NAT/Firewall problem or 3) Freeswitch internal profile running on local machine ipv4 192..... and I logging on using the router external IP 76.XX and the Alias didn't do the job????? </div>

If you're able to dial in but you're getting no sound, it's probably<br>
NAT stopping the audio get through.<br>
<br>
There's quite a bit of information on NAT on the Wiki that might be of use.<br>
