If your system is behind a firewall, try adding 'insecure=invite' in your sip.conf's general section.<br><br>To troubleshoot such cases, do a tcpdump trace like this:<br><br>1. Run tcpdump on your server before making a call. Use command "tcpdump port 5060 -s0 -w dumpfile.pcap".<br>2. When you notice the silence problem, hangup, and stop the trace using CTRL+C.<br>3. Copy the dumpfile.pcap to a computer with Wireshark installed.<br>4. Open this file in Wireshark and follow my blog at <a href="http://ilovetovoip.com/2010/02/graphical-illustration-of-the-sip-messages-using-wonderful-wireshark/">http://ilovetovoip.com/2010/02/graphical-illustration-of-the-sip-messages-using-wonderful-wireshark/</a><br>5. Given that you know some basics of how VoIP works over SIP, the wireshark graph will tell you if RTP was still flowing when it was silent. It probably is, but to which IP address.<br><br>My guess is your RTP, i.e. voice date, starts flowing towards some wrong IP address, or stop flowing, or is blocked by the router.<br><br>A good solution is to put your Asterisk server in DMZ mode.<br><br>There can be many other guesses, but the above is a good start.<br><span class=moz-txt-tag>-- </span><br><br>Zeeshan A Zakaria <br><br>PBX - visionvoip.com <br>Blog - ilovetovoip.com <br><br>On 18/10/2011 10:02, Aksel Celasun wrote: <o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'>Thank you for replying</span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='color:#1F497D'>My sip.conf is set to no on canreinvite</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-language:NO-BOK'><o:p> </o:p></span></p></div></body></html>
