ESI Communications Servers - These business class phone systems combine the ultimate in digital communications with voice over IP capability into a powerful and scalable platform. One of the most powerful aspects of the Communications Servers is that they all posses the SAME FEATURE SET from the smallest phone system to the largest phone system.

	CS 50 - The smallest of the servers, the CS 50 starts out in a four line by eight digital stations in it's capacity and can expand from there. Even in at its reduced capacity the CS 50 is still able to handle a digital PRI circuit and can be configured to support VoIP.
	CS 100 - The mid-size phone system class is absolutely dominated by the CS100. Combining a strong starting capacity with the ability to use the larger blade adaptable cards the 200 through 1000 use.
	CS 200 - The CS200 is the first in the starting line up of the larger capacity phone systems. It uses the larger capacity blade style cards and is positioned for mid to large size businesses.
	CS 600 - The CS600 is quite simply a CS200 that can expand to a larger over all capacity. It is the next in the line up of blade style, rack mountable digital business phone systems.
	CS 1000 - The titan of the blade style, rack mountable digital business phone systems. It is the flagship of ESI and is positioned to take care of the largest companies in the SMB market place.
