Hi all,

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:

Aug  3 04:36:09 localhost kernel: nf_ct_sip: dropping packetIN=eth0 OUT= 
MAC=f2:3c:91:ae:92:36:c8:4c:75:f5:c4:ff:08:00 SRC=122.xxx.xxx.77 
DST=xx.116.xx.23 LEN=1482 TOS=0x00 PREC=0x00 TTL=51 ID=50183 DF

RES=0x00 ACK URGP=0 OPT (0101080A000E20610932B25A)

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.
