The PIKA µFirewall helps to identify and prevent toll fraud on a premise-based IP PBX before it happens. It does this by analysing SIP packets through deep packet inspection and stopping abnormal SIP protocol usage based on pre-determined parameters.
This small device is easily installed plugs in front of your existing telephone system on-site and can be remotely managed. You are able to customise the whitelist and blacklist and send custom event notification emails.
