thanks for replay

As i see may be iam wrong from ur link that i choose certan ip and block it now , if certain ip hacking me now i want the block happen directly to this ip as it send so many trafiic to me how we can do this
??

can you provide some detail info. Like your provider, web browser, OS, etc

iam using  http://www.brekeke.com/ as sip server running on windowes 2003
ans i also use symantic as firewall or antivirus

i'm a little confused, you want to block a specific IP address or anyone that tries to hack your system???

no not spesific ip address , i want to block any ip that try to hack my server by sending many traffice

A good firewall and anti-virus should already being do this for you. I know my software notifies me when someone is attempting to get into my system. Here's a link yo some good security practices for VOIP users. Sorry I couldn't be more helpful:

is there any other sugestions for my situation ??

I am sorry but know one is going to be able to suggest a solution to do what you want. There is not a simple program you can install that will guaranty the security of your system. I wish it were that easy.

You need to hire someone to secure your system, that is able to do a through evaluation of the risk and can suggest solutions to match.

Your system can be secured you just do not have the knowledge to do it.

ok from where i can get some one trusted ?

I would check to see if there is anyone in your area that is listed as a certified security expert in your local area.

Google or your phone book should give you a good start, I would then check to see if they are certified GIAC provides listings at their site http://www.giac.org.
