VoIP Protection at its Best

Do you have a legacy phone system, such as a TDM PBX and are thinking about adding a Voice-over-IP connection to reduce telephony costs? Well if so, don’t make the most common mistake of using you’re the network’s firewall for voice security – You need a device calls a Session Border Controller.

PBX Fraud is increasing each year as legacy telephony networks integrate VoIP without properly securing with an SBC. Don’t be part of the statistic! A typical firewall can only protect your data network and as soon as you as you open it up to the internet, which is how you connect to VoIP services, the entire network is exposed. This means both your data and voice networks can be compromised which can cause your telephone bills to skyrocket or become susceptible for hackers to breach your system and take down the network.

A Sangoma SBC protects both your data and voice network and is designed to handle every aspect of phone calls that travel over the internet (or voice-over-ip phone calls).

All SBCs are field upgradable and licensing is per session based, which means all the features are always included – No sticker shock. Predictable SBC capacity and cost in every use case.

Protection against malicious attacks such as Denial-of-Service, Fraud, BYOD, and SIP & RTP flooding. Toll fraud protection against hackers breaking into VoIP systems causing financial turmoil. Topology hiding for protection against exposing network routes.
diagnosticsDiagnostic Tools
Browser based dashboard featuring time based graphing, system and session error reporting and email notifications upon faults. Onboard PCAP training tool capturing signaling and media, eliminating the need for extra port mirrors or hubs. The Hardware Crash protection feature reboots the system on lockup or hardware fault.

Use Cases

The main reason to implement an SBC into your network is to provide full security when introducing VoIP into your network. Whether you are an enterprise or a carrier, an SBC is critical to have end-to-end. Even if the remote side of your connection already has an SBC, remember that wherever an internet connection is introduced is an opportunity for hackers to compromise the network.
