Our Customers

I would recommend National Telesystems for all of your phone equipment, programming, and service needs. Thank you to all the sales team, client service members, and techs that helped us through our phone system selection, install and custom programming needs.

We recently updated our business phone system. National Telesystems installed our previous phone system in 2007 and even though we solicited quotes from other phone companies for our new system, none of them compared with National Telesystems! During our review of new technology, they explained everything in easy to understand terms so we knew what hardware and services would best suit our needs. The installation was flawless and the follow-up and training were right on target.

M D I Inc. General Contractors

We recently moved our office and had to find a capable team to move our old Nortel phone system. My questions were answered ahead of time and all concerns about moving an old system were discussed prior to scheduling. Very professional. Our installer was also knowledgeable and thorough. Our phones were moved, installed, tested and approved within 3-4 hours. Highly recommend National Telesystems.

Joseph Noble Textiles

Fantastic company to work with, I honestly couldn’t imagine how it could get much better. Very responsive salesperson, we had a lot of construction delays so we had to rearrange scheduling more than I liked, but they were happy to reschedule us every single time. Nice people, knowledgeable about what they sell, and it really seemed like they wanted our business.

Changing phone systems is a difficult position to be in. As we shopped for the best value National Telesystems separated themselves from all of the companies we interviewed. Their proposal was professional, and exactly what our vision was. The implementation was seamless and very professional.

West-Hurtt Funeral Home

My Company replaced a 10+ year-old phone system with a new one through National Telesystems Inc and the whole process was great from the point-of-sale, project management, installation and add-on services. The actual switchover was seamless from the old to the new systems with absolutely no interruption to our workflow and it was a hassle-free process that made me breathe easier as the accountable manager of the project and for the entire Company.

National installed telephone lines and equipment some years ago for our first restaurant and just now helped us set up services for our newest – telephone, internet and more. I truly appreciate how they went above and beyond to make sure install went smoothly, stepping in to navigate between landlord, neighboring businesses, riser management companies, internet service providers and others to get us up and running.

David Jeiel

Bavette Grill

We have worked with National Telesystems for over 20 years and they had installed our original telephone system. Not only did the equipment stand the test of time, their customer service and support teams have always done a phenomenal job in helping us anytime we needed it. One of the BEST companies I have ever had to do business with.

Gandy, Calverley & Co, CPA

I’ve been doing business with National Telesystems for over 15 years and would recommend them to anyone needing a dependable telephone system vendor and support team. We started as a small company and over the last 15 years we have grown and moved, upgraded systems, and needed repair support and all was handled flawlessly by National.

We are a small commercial construction company that just updated our business phone system using National Telesystems. From sales, to installation, to training, to follow up, their staff was professional, courteous, prompt – and determined that we be very satisfied customers.
