Our company has had NTI for a number of years, but we added new staff to our team and needed to update our systems. Multiple people on our team read through all the phone manuals multiple times and searched online to find what we were looking for, but we should have just called NTI directly. Because on the first ring first thing in the morning, we reached Jennifer J. at NTI and within 30 minutes, our entire phone system was updated because of the simple instructions she was able to send to us so quickly! We LOVE them and so appreciated their helpfulness, ease of instruction and care!

Good Morning Terry,First, I want to thank you for hiring such an amazing people. Jennifer assisted me with some issues about two weeks ago. I was at my wits end trying to figure out why our phones were not working, and Jennifer came to my rescue. She was so helpful and kind right from the jump. She went above and beyond making phones calls to figure out what was happening and returned my call promptly to assure me that she was working on the issue. She also was able to schedule a tech for the very next day, talk about staying on top of it!! She followed up once we were back online and operational! It’s so nice to have someone you can depend on. Jennifer made my day so much better just by being her. Kindness and eagerness to help your customers goes a very long way! Just thought you should know that you have a keeper! Thanks again for hiring such great people. Hope you are having a nice day!

We have worked with National Telesystems for several years. During our recent move, they provided us with great service, recognized and accommodated us when work became urgent and met our needs all the through the process. Working with this team was a pleasure and I would highly recommend National Telesystems for your telephone and cabling needs.

Excellent partnership where the COO walked the project in advance to assure they would meet our schedule. Great planning and execution by the onsite team. Flexible, customer centric and responsive to identified problems. I highly recommend them.

My Company replaced a 10+ year-old phone system with a new one through National Telesystems Inc and the whole process was awesome 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. I enthusiatically recommend National Telesystems Inc.

If you're looking for a seamless phone upgrade for your business, look no further. We have worked with National Telesystems for years simply because their knowledge and customer service is unmatched. They installed a new system for us yesterday in the middle of business hours and our down time was maybe 5 minutes. With changes to our business due to COVID, they easily accommodated the need for a work-from-home phone that can transfer to in-office phones, an app that can be used from your cell and easily changeable settings for the ever-changing office set up. They're the best!
