dear<br>
i have configured properly asterisk. At the one end i am using x-lite soft ph and another end twinkle. call is going properly from both end but after picking the phone not able to listen other one.<br>
when i checked the port 5060 on the asterisk server it is always showing closed while i have flushed all the rules from iptables (iptables -F)<br>
<br>
PORT STATE SERVICE VERSION<br>
5060/tcp closed sip<br>
<br>
telnet localhost 5060 (could not connect)<br>
<br>

SIP is only used to setup (and stop etc.) the call. The actual audio is sent via rtp.<br>
<br>
/etc/asterisk/rtp.conf<br>
<br>
Should tell which ports asterisk is using for rtp, you will need to make sure that the remote host can connect to these ports.<br>
<br>
There are lots of articles around on how to resolve this.<div><div><br>
