Equipment Buy-back: We buy some used phones and equipment that is still in working condition. Should we not have a need for a particular brand, we will be glad to list it and help you make the sale.


Referrals: Should you have a phone system we can not program, or a network issue that is beyond our means, we will refer to you a vendor with experience in that particular area that you can trust to resolve the issue at a fair price. We will also keep in touch with you to make sure everything is on-track and meeting your expectations. We are here to help you.


System Relocation: If you are planning to move to new offices, your voice and data systems need to be moved as well. Our staff will assist you with all phases of moving your systems. We will plan the move with you, and then handle each step of the relocation. One of our Project Coordinators will oversee the removal and installation of all equipment, and will insure that all telephone sets are placed and programmed to your satisfaction. Contact your Account Representative or a Customer Care Representative for all your telecommunications and network systems needs.


Local and Wide Area Network (LAN/WAN) Connectivity: With the convergence of voice and data networks it becomes very important to have extensive knowledge of both. At Reliant Communications we have this knowledge and understanding of how to implement and maintain these converged networks. This knowledge only comes with years of experience which we have and is passed on through the work that we do. We have implemented many LANs / WANs for our customers using the products we sell.
