Run 'netstat -anp | grep freeswitch' and see whether FS is still listening

Cal's 'grep LISTEN' command will only show the TCP ports, if SIP arrives
on UDP those ports will appear with the above and it'll show all ports (that'll include RTP ports for active calls, but given the problem I'm guessing there won't be any/many).
If restarting FreeSWITCH doesn't help and only a reboot seems to help, it would match a bug I have seen in iptables before. Try unloading the SIP conntrack module and allow all packets into your server (ie disable the firewall) and see if they start appearing. I have seen that module randomly start blocking all packets from getting through the firewall but never found why (moving to stateless and avoiding the conntrack module stopped it). That was on an old 2.6 kernel so hopefully isn't present in newer kernels.
If just restarting freeswitch helps that's not iptables. Trying to reproduce it on the very latest version of FreeSWITCH would be a good start. -Steve

Steve,
Thanks for your response, I have tried with global siptrace turned on and I see absolutely nothing when I make the call, the SIP INVITE messages are sent to the FreeSWITCH host machine as seen using WireShark running on that host.
Chris.

Try enabling the sip trace when it happens to see if FS receives the packets: sofia global siptrace on

Hi, I’m new to FreeSWITCH lists and I’m not sure if this is the correct list for my post, any help will be much appreciated.
I have a FreeSWITCH server configured to connect to a Draytel (draytel.org) SIP service. This works correctly and I can dial in and out using the service.
I have an application running on a Windows Server that interfaces using event socket to the FreeSWITCH server. The intended use is that calls dialling in through the draytel service are automatically handled by this application. Again this works correctly.
However, after a period of time which does not yet appear to be deterministic the FreeSWITCH server stops responding to INVITE requests from the draytel server. The FreeSWITCH server can still respond as I can dial using a local network VOIP phone and the application handles that call, but on the draytel connection there is no response.
When FreeSWITCH stops responding I see absolutely nothing in the output logging information. I have run WireShark on the server that is running FreeSWITCH and I can see SIP INVITE requests being sent from draytel to the FreeSWITCH host but I don’t see any kind of response.
Help! Thanks
Chris.

Hello, I'm also new to Freeswitch and facing similar issue when FS not responding to Invite messages after several minutes (between 7 to 15). I set the siptrace on and see that no packets arrived (when the other leg hanged up I could see the packets). We are running FreeSWITCH Version 1.2.7+git~20130307T054051Z~0a2e713593 (git 0a2e713 2013-03-07 05:40:51Z) On ubuntu release 12.04 Please help. Thanks Zvi Agmon
