Customer Testimonials

Two companies, AT&T® and CSI, unite their strengths to work together on your behalf.

In order to best serve our customers, AT&T® has joined forces with a network of Authorized Agents whose capabilities complement our own. These Authorized Agents are independent Value-Added Resellers and network consultants who are trained and authorized to sell AT&T®'s world-class business communications services, including Internet access, data networking, web hosting, local and long distance. We work together to provide customers with custom solutions that powerfully and efficiently address their communications needs. We have found that this synergistic approach helps to achieve optimal customer satisfaction.

As AT&T® Authorized Agents, we have access to world-class sales support and industry-recognized educational programs. In order to become an AT&T® Authorized Agent, CSI, Inc had to meet stringent requirements.
