asterisk users - Dec 2007 - Cirpack KeepAlive packets causing SIP errors

Hi list,

After a recent upgrade to Asterisk v1.4.14, my message log is now  
filling up with
the following error messages:

<------------->
[Dec 29 17:24:52] WARNING[10655]: chan_sip.c:6645  
determine_firstline_parts: Bad request protocol Packet
--- (1 headers 0 lines) ---
bitis*CLI>
<--- SIP read from 82.101.62.99:5060 --->
Cirpack KeepAlive Packet
<------------->

Seeing as these packets are being sent by one of my service providers,  
I can't just turn them off. What's the best solution for this problem?

Thanks,

Jaap

Are you using XS4ALL ?
I had the same and convinced oej those warnings are
annoying.
In trunk he moved them to DEBUG:
http://svn.digium.com/view/asterisk?view=rev&revision=93741
Maybe you can backport this change.
You can also remove the ast_log line. That's what I've been
doing for some time before oej committed this move to debug.

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.
