VoIP systems and solutions are the hottest new trends in telecommunications today. However, businesses accustomed to the reliability and ease of implementation of traditional telephones in their business may be surprised if they explore this new arena without knowing the precautions to take. VoIP technology can be a strong benefit to many companies, and National Telesystems consultants take our customers through the "ins and outs" of VoIP to show them where it might be beneficial to their operations. On the other hand, National Telesystems also will tell a company when we do not feel VoIP is worth the investment to their company at this time.
When a new technology such as VoIP emerges, new companies come "out of the woodwork" trying to capitalize on the hype. Without the background and structure, these new ventures come and go with regularity, often leaving their clients without phone service and a host of related problems.
National Telesystems has invested heavily in VoIP training and product for years to make sure we are on the leading edge of this technology but not the "bleeding" edge. National Telesystems has the experience and expertise with VoIP to make sure our customers get the most out of this technology!

Through our varied resources such as trade-ins, repossessions, and buy-backs, National Telesystems has acquired many top-notch used telephone systems that we resell at excellent prices.
Every used system we resell goes through a complete reconditioning, multilevel testing and quality evaluation before it is sold to our customers. National Telesystems has a complete in-house testing and reconditioning facility, and any part made available to sell must meet top quality standards.
We back up our testing with a warranty on every part we sell, whether it is a telephone, a central processing board, or software. This is absolutely critical in Texas, where lightning storms are commonplace. Lightning can completely destroy the operability of a telephone system and never leave a visible trace that it has happened. The only way one will know is once they have installed and used it. Many businesses have been burned by the "it looks good, it must work well" fallacy. National Telesystems warranties insure our customers get what they receive a quality telecom product that works as it is supposed to. In business, telephone communication is too important to accept anything less.
National Telesystems prides itself on having one of the finest service departments in the country. Our certified professional technicians specialize in speedy diagnosis and repair on a variety of telecom systems, making sure "problem-time" is kept at an absolute minimum.. In addition, by attending continued education classes, National Telesystems technicians stay on top of the latest techniques and software, insuring our customers receive only the best service.
National Telesystems also stocks one of the largest replacement parts inventories in the country. When a part needs replacing or a customer wants to add to their system, there is almost a 100% chance that National Telesystems has that part in stock.
Fast service, quality technical supports, parts availability - it all adds up to taking care of our customers and their telecommunications' needs quickly and expertly. We look forward to serving you!
National Telesystems stocks equipment and services systems from most major telecom manufacturers. If you want service or parts for Norstar, NEC, Samsung, Avaya Partner, Vodavi, Starplus, Vertical, Toshiba DK and EK, WIN, Telekol, Landmark, Southwestern Bell, TIE, or AT&T - please contact us.
