How can I reject and block them?

Thank you

- Refer the section "8. Security" on the document
http://www.brekeke-sip.com/download/bss ... min_en.pdf

- Use the Address Filtering at [Configuration] > [System] > [Address Filtering].
If you have list of trusted IP addresses, select the "allow" in the [IP address filter], and set these IP addresses in the [Filter pattern].
For example: ^172.16.0.10$|^172.16.0.20$|^192.168.0.+$
(Refer the section "3) Address Filtering" for more details.)

- Use a firewall in the front of SIP Server to block unknown remote IP address. (If possible)

- Use the latest version of Brekeke SIP Server.

- Use the following DialPlan rules to reject such an attacking packet.

Thanks!
