[asterisk-users] Cirpack KeepAlive packets causing SIP errors

[LInux]

Have a look at this:

If you are running on linux (with a recent kernel), add the iptables 
firewall rule to drop the bad packets:

# drop Keep Alive packets from Cirpack SIP proxy xs4all
/sbin/iptables -A INPUT -p udp -m udp --dport 5060 -m string --string 
"Cirpack KeepAlive Packet" --algo bm -j DROP

Worked for me.
