What does NUSO mean?

NUSO means “transparent” in Esperanto, the most widely spoken constructed language in the world. L. L. Zamenhof, a Polish ophthalmologist, created Esperanto in the late 19th century to help bring peace among different people and end global conflicts. “NUSO” represents our company because we believe in transparency. This openness translates into focusing on our partners and the tools we give them – As a Channel Focused SaaS company, we make sure our Partners deploy, monitor, and manage their customer’s services in real-time.

Client Testimonials

We want to take a moment and give a huge shout out and thank you to NUSO! Today, we simultaneously ported over 88 phones at 7 different locations to a new Unified Communications as a Service System, all in under 30 minutes. This was by far the largest and easiest transition we have done in our 15 years in the telecommunications business. So, thank you, NUSO, we are beyond thrilled to be partners with such a terrific company! Pioneer-360

The NUSO team has taken such good care of us. They consistently reach out to make sure we have everything we need. When I do need something, it doesn’t matter – big or small, my guys at NUSO are ready! Oh yeah, and support is SPECTACULAR! Probably the best support I’ve ever had. Creed Technology

To start, our company has worked with several providers in the past. All talked a big game, but none delivered. We were looking not only for a solid company to work with, but a company that focused on providing easy to use software. NUSO’s partner tools are designed with this in mind – they let us do our jobs in real-time. We can quote, add new phone numbers, and make our customers happy. Plus our account manager, Silvana, is always there when we have questions or need extra help. The entire team has proven themselves to be capable partners. Mastor

Exceptional customer service is core to Cadence and finding great partners in any industry can be a challenge. NUSO is a great partner because they share the same mindset. The core ideology is to listen to understand, not listen to respond; which leads to a fine-tuned solution and a superior customer support experience. The Cadence NUSO team approach is dramatically changing the client perception of network solution providers.

My business depends on having the right partners when I need them. NUSO provides me and my clients with optimal coverage across the telecommunications space. Their teams are supportive and available when I need them, NUSO has been a great resource to me and my business. More importantly is the great relationship I have with my Channel Account Manager. She has been with me since I became a partner with NUSO. Few companies have the long-tenure and deep working relationships that l’ve been able to build with her. Knowing that she is on my team makes working with NUSO an easy choice for me.

My name is Jose-Raul Lopez, under my company J R Servicorp, I have been selling equipment and services to my clients in Broward, Miami-Dade and Palm Beach counties, Florida since 1992. When I speak and recommend NUSO to my clients, I do it because it is my own clients who receive the service who return their satisfaction, regarding the quality and reliability of their telephone conversations. But when I speak for myself, I recommend NUSO to my colleagues for the fast and excellent technical and sales support, as well as the excellent tools I have on my NUSO portal.

I would like to take this opportunity to Thank All at Nuso who have helped grow and support our Nuso Voip Business Partner Customers. Before we became a Nuso Partner we had the opportunity to install a number of different Hosted Cloud Provider Voip Platforms. Without any reservation, Nuso has been the best fit for us, and our Customers. Businesses have many choices and are solicited constantly with Hosted Cloud Telephony Products. We can only hope to get one shot at earning their Hosted Voip business and keeping it. I believe Nuso gives us the best chance for success and Customer retention we all work so very hard for.

Alamo Communications

Our company has been in the telecom business since 1992 selling traditional telephone systems. With the change of the telecom world, we needed to find a great partner to help us provide our customers with a product that would fit their needs. We tried a few other vendors before coming to NUSO as our primary source for cloud solution. We have been selling NUSO Cloud since 2018.

We find that the scalability of the product is a big selling point for our customers. The NUSO team makes our job easy, from working with our account manager, implantation and porting teams. Tech support was one of our main requirements of a cloud provider. The NUSO tech team is one of the main factors that has contributed to us staying with NUSO. We are a very hands-on customer support company and working with NUSO, has made us a cut above other companies offering cloud solutions in our area.

We look forward to our continued partnership with NUSO.
