[SR-Users] Kernel Droping SIP packet

[Vijay Thakur]

Thanks for prompt reply.  Here is the out put if command iptables -L -n:

*Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Thanks for prompt reply. This is a Ubuntu 10.04 Kamailio 3.1 Server.

You might consider pasting the actual output of: iptables -L -n

This lists the actual rules straight from netfilter at runtime. I wouldn't worry too much about what some distro-specific config file or script says. Real truth comes from iptables itself.?

I have configure Kamailio 3.1.5 Server. All things are working fine.
When i make a call from Soft phone (X-Lite) to iphone, all is working
fine. But in other case call from iphone to Softphone is not working,
even not ringing. During checking the logs i am getting the error:

I have not implemented any firewall. You can check the out put of my
iptables :http://pastebin.com/i3zUfVeb
The SIP server is hosted at linnode.

With thanks in advance. Sorry dual posting.
