thank you all for your support. I am using Linux, I only have about 7 users outside our home network. I will learn fail2ban and will use it accordingly. 

again Thanks for your support.

I don't know what platform you are on, but if you are on Linux (and possibly BSD) you could use "fail2ban" to block them at the network interface.

      I second fail2ban. If you need some ideas to configure it, you can steal them from the freepbx setup.

      How many sip phones do you have outside your network? If few and in well-known IPs, consider limiting access to only those (and the sip provider you are using).

is there a way to reject their registration after a three consecutive tries?

Thanks,
