National Telesystems knows NEC DSX Telephone Systems!  We have installed more NEC DSX systems than all of the other Dallas Fort Worth NEC Dealers combined!  

Is your business one of the many whose phone company that installed your NEC DSX system has gone out of business?  Or perhaps you are frustrated that your phone company “never gets it right” and have to keep coming back, all the while frustrating employees and customers?  Or maybe you have asked questions about the time-saving and money-saving features that you have heard can be added the system and your dealer just tells you it will not do it (because he has no idea it will).  WE HEAR THOSE STORIES REPEATEDLY!  For example, many NEC phone system installers have no idea they can add cost saving SIP service to the DSX.  Others are not trained on the great call tracking applications and just tell their customers “Not Available”.  Or how about the full range of call recording options?  Many dealers have only ever had experience with the recording in voice mail, which is by far the most limited recording option available on the DSX.  Call recording is absolutely essential for legal reasons in many industries today, and the DSX has some outstanding options, but ONLY IF YOU DEALER KNOWS ABOUT IT!

Call National Telesystems today.  Get it done right the first time.  Get the most out of your phone system investment and find out what your system will really do.  We at National Telesystems look forward to serving you!
