voipTIK - "Wow ... its working ...a perfect voip shield" a direct quote from one of our clients

Is your public facing PBX'sWhat does public facing PBX mean? A VoIP service that is available to the general public. The term refers to any free or paid application or system [like VoIP service] that the public can access and subscribe too. Also called "customer facing," information systems often comprise a public-facing component as well as a private side that is available only to the internal staff getting a lot of SIP/VoIP attacks?

If your answer is YES then you need to consider our voipTIK Blacklist service - a perfect voip shield to protect your business and PBX's against VoIP Fraud and minimize the risks of attacks on your Telephony Server.

Currently recording 57,978 IPset entries that cover 76,250 IP Addresses of known attackers

The VoipTIK blacklist is specifically engineered to run on MikroTik Routers like the CHR [Cloud Hosted Router] and CCR's [Cloud Core Router series] utilizing MikroTik's RouterOS Firewall. When using our voipTIK blacklist service - in the MikroTik Firewall - you will need to whitelist all your core servers for all ports, hosted PBX's and Interconnection partners to specific required ports before implementing the drop rule for the voipTIK blacklist.

The whitelist filter rule would be put in IP/Firewall/RAW positioned as the 1st rule and looks as follows:

/ip firewall raw add action=accept chain=prerouting comment="whitelisted SRC-addresses" src-address-list=voipwhitelist

On the Tik Router the voipTIK blacklist is scheduled to update every 4 hours when ipset addresses are triggered for adds/subtractions on a 24/7 365 basis.
