When we deploy VoIP system in public networks, miniSIPServer is often attacked by some hackers. To defend that, we wamt to block all SIP packages from specific IP address directly to protect VoIP system.
In another way, we can also trust all SIP packages from some special IP addresses, for example, from VoIP gateways, or from enterprise private network, and so on.
With "IP address black & white list" feature, we can trust some IP addresses, and we can also block some IP addresse. If an IP address is in black list, miniSIPServer will discard all SIP packages from such address directly. If an IP address is in white address, miniSIPServer will disable "fail to ban" and accept SIP packages from it.
Please click menu "Services - IP address black&white list" to configure this feature.
Below table describes the key items of this configuraiton.
|IP address||IP address which is in black list or white list. It can be IPv4 address or IPv6 address.|
|Action||miniSIPServer action on this IP address.
"Accept" means the IP address is in white list and miniSIPServer will accept all SIP packages from it.
"Reject" means the IP address is in black list and miniSIPServer will reject all SIP packages directly from it.
