Telephony FirewallsRSS

A telephony firewall is designed to protect a telephone exchange or PBX, reporting on a variety of attacks, commonly referred to as phreaking. This may range from misuse, for example if a preset threshold of particular calls is exceeded, to attacks against the exchange such as wardialing, where many telephone extensions are called in order to solicit information about the end user device.

 

This section also includes VoIP or SIP-Aware firewalls.  SIP-aware firewalls have the ability to inspect the packets coming into the firewall and distinguish SIP voice traffic from regular data and allow SIP traffic to pass through without having to open ports, which opens the door to security issues.

 

Home/SOHO products that are VoIP or SIP-Aware are not included in this list.
