Hi all, I have sometimes a really interesting problem. Sometimes my server is not reachable from xlite. Xlite give me Request Timeout error. Also if I start xlite on my server they can not be registered on FS. If I try "telnet xxx.xxx.xxx.xxx 5060" a connection is established. HTTP and all other services are available. But FS are not available. For test I installed another sip server on the machine (Voipswitch Demo) so I see that works. But FS gives not response. I check my network and many other things. Also I change my port on vars.xml <X-PRE-PROCESS cmd="set" data="internal_sip_port=5060" /> <X-PRE-PROCESS cmd="set" data="internal_tls_port=5061" /> But nothing is changed. After 1 or 2 hours FS is available and works again. This problem is during up 1 time in 1 month. I don`t understand what is wrong. Maybe a mistake in my configuration? Maybe everybody have an idea? Greetings Erkan
