In the corporate environment which deploys a VOIP solution, it might define a designated network number or a network vlan for that VOIP service. However, can any one person or product constantly ensure that IP phones are physically connected to the right network sockets (ports)?  Or verify that the PC device has not been attached to the VOIP network?

As probable and common as this scenario may sounds, the available Network-Access vendors cannot help. They cannot differentiate between a PC device and a Telephony one. Unlike those technologies portnox™ can identify, authenticate and authorize any IP device at the plug-in port.

A corporation may save some wiring and a negligible cost, if they use convergence to deploy the VOIP. However, by doing so the corporation opens the door to major security issues. The risk of convergence is simple to see and understand as follows:

1. An IP telephone device is assigned a specific network number.
2. A PC device is connected at the back of the telephone and uses another network number.
3. The PC manually shift from the data network over to the voice network.
4. The corporate VOIP network integrity & security are compromised.

Unlike in the days of plain telephony architecture, nowadays any PC user can manually assign his PC to shift from the data network over to the voice network!   And there is NOTHING your switch or voice vendor can do about this manipulation to avert the risk.

Only with the portnox™ protection can a company safely manage and secure its VOIP deployment; each IP telephone is in clear sight; each IP device can be tracked, traced and monitored; each logged-on device is a legitimate one and the port location where it logged on is constantly display . portnox™ allows no other device than a legitimate and authenticated IP telephone to attach to the voice network. portnox™ provides the network with the absolute integrity needed for managing and securing a corporate Voice Network Operation.
