The expanding adoption of digital telephony and teleconferencing in today’s business has launched VoIP technology into the IT mainstream. As customers’ IP networks continue to grow by adding voice and video, along with high bandwidth data applications, the need for greater security, control and access becomes critical.
Like all IP traffic, VoIP can be prone to security threats from internal and external attacks and application vulnerabilities. VoIP is particularly susceptible to Denial of Service (DoS), digital eavesdropping, toll fraud and trunk hijacking. However, potential latency, jitter, packet loss and echo due to an underperforming firewall could significantly degrade communications.
Administrators must be able to prioritize allocated bandwidth to VoIP traffic to ensure adequate quality of service (QoS). Underperforming firewalls can potentially degrade VoIP communications with latency, jitter, packet loss and echo.
Virtual Private Networks (VPNs) have become a key component of converged networks that allow multi-site organizations to design one large private network as opposed to separate networks for each location. Increasingly, users require remote and mobile access to VoIP applications, and securing this access is critical.
The ideal solution would include control over QoS prioritization, comprehensive security that introduces no latency, and secure access to VoIP applications over VPNs.
