Core Competencies:

As a NEC Authorized Distributor, we market, install and service a variety of NEC offerings such as: Telephone Systems, Voice Mail Systems, Servers, Cloud Services, SIP Trunks, Display Screens/Digital Signage and coming soon Facial Recognition. We also have a In-House Call Center/Answering service, IT Services, Consulting Services, Voice and Data Cabling, Voice and Data Circuits through Windstream, AT&T, Spectrum and more.


Accomplishments: Allied Technologies installed new fiber in the Glen Oaks Office Park in Mequon, WI to connect 6 multi-tenant office buildings. Now we are able to service all buildings through our new fiber connectivity with voice and data services. For our Senior Living Customers, we designed and developed a system for them to resell dial tone to their residences thus creating a new revenue stream for the facility. We have used the same system in multi-tenant office buildings and apartment buildings creating a revenue stream for them as well, and creating a unique offering for the tenant upon moving in, by having phone and internet service up and running the day they move in. Testimonials: Our company has trusted Allied Technologies for phone and IT services for over a decade, and we value their expertise and reliability. As part of our recent remodel, we are now using their digital signage product in our customer waiting areas, and the response has been terrific. We have received many compliments on the look of the signs, and the flexibility of the product lets us easily manage the content. The process of working with Allied on the product demonstration and installation was a pleasure. Mike Delmore VP/Controller Hall Imports We have relied on Allied Technologies Online for call center services for us and our tenants as well as cabling and voice and data services for over 15 years. Most recently, Allied has updated the lobbies in all of our office buildings with new digital signage displays to replace our old tenant directories. The feedback we have gotten on this upgrade has been very positive. Our lobbies have received a new modern look. We have also relied on Allied Technologies Online for business telephone systems and circuits. We would highly recommend them for any digital signage or telecommunications needs. Bill Mikkelson Vice President Mikkelson Builders John, thank you so much for your assistance in getting our phones up and running. Beth and I would have had no idea how to handle that situation on our own. It certainly would have taken longer if we had tackled the issue left by AT&T. You were professional and proactive and we appreciate it. It has indeed confirmed what we already believe about your firm. You've been more than helpful and we will certainly keep you as our go-to communication provider moving forward. Thanks again and have a great weekend! Jon Welch Operations Manager Crawford Tree and Landscape As the person who serves as an intermediary between customers and ATO as the technical service provider, I have found their service to be excellent.
