Voice over Private IP: Seamless and Secure

For many carriers, voice over private IP is emerging as the focal point for industry efforts to define standards and best practices. Large wholesale carriers, many of whom own and operate global IP backbones, are examining private IP for its advantages in quality, control and security.

By using their own equipment, carriers have much more control over important IP quality metrics, such as latency, which in turn leads to better voice quality. Carriers can roll out cross-connects that are dedicated to voice, enabling further optimization.

Private networks also offer higher levels of security than the public Internet, which has the potential for hackers to listen in to or steal phone calls are caller ID information. By interconnecting into each others IP backbone they can be assured of protection from outside access that the Internet cannot provide.

However, regional carriers or other service providers may find that the ease and ubiquity of the public Internet outweigh some of the benefits of private networks, while most wholesale carriers also make voice over Internet part of their strategy.

The success factor for service providers is to identify what needs and goals should be served through a transition to IP, and identify a model – public or private – that aligns.
