By choosing ADC Technologies, you gain access to more than just advanced phone features, you unlock a fully integrated unified communications platform. This all-in-one solution streamlines your business communications under a single, reliable system, enabling seamless collaboration and exceptional customer service.

We take a customized approach to every deployment. ADC works closely with each client to design and implement a business phone solution that aligns with your current needs and future goals, whether it’s integrating with existing infrastructure, scaling with your growth, or transitioning to a completely new communication model.

From technical features to user-friendly tools, ADC’s business phone systems include everything your team needs to stay connected, internally and externally. Below are some of the key capabilities included in our unified phone solutions

Integrated Call Management and Collaboration

  • Personalized Call Routing – Find Me/Follow Me functionality allows users to create custom rules for routing incoming calls to specific devices, whether they’re company-owned phones or external numbers. With VIP call handling, only priority callers can ring selected devices, ensuring critical calls are never missed.

  • Built-in Presence and Chat – Integrated presence indicators and instant messaging enable team members to quickly see who is available and communicate in real time. Employees can easily identify colleagues who are on a call, streamlining collaboration and reducing delays.

  • Enhanced Collaboration – The system supports seamless integration with tools like Active Directory, Azure, Office 365, Salesforce, video conferencing platforms, and SMS messaging, bringing all communication and collaboration channels into a unified experience.

Distributed Worker Support

  • Mobile Phone Integration – Business calls can be directed to employees’ mobile devices using dedicated Apple or Android apps, allowing staff to remain reachable during business hours, whether in the office or on the go.

  • Desk Phone and Softphone Support – Employees can access full office phone functionality through VoIP-enabled desk phones or softphone applications on their PCs. This ensures seamless communication, even when working remotely or away from their primary workstation.

  • Multi-Location Integration – A unified cloud PBX system allows all office locations to operate under a single phone infrastructure. This provides a consistent caller experience across branches and helps organizations maintain a professional, cohesive presence.

Trouble-Free Administration

  • Flexible Auto Attendant – A customizable auto attendant system ensures incoming calls are routed to the right person or department. Its adaptable menu options provide a seamless and professional customer experience.

  • Web-Based Administration Panel – The intuitive control panel makes it easy for administrators to manage phone system settings without relying on IT support, saving time and increasing operational efficiency.

  • Comprehensive Reporting – Access detailed call logs and real-time queue status through a user-friendly reporting dashboard. Administrators can monitor performance, analyze historical data, and generate insights to support employee evaluations and call center optimization.

  • Emergency Management & Recovery – Stay prepared for unexpected events with customizable emergency call routing, automated greetings, and temporary auto attendant options. This feature helps maintain business continuity and reassures clients during office disruptions such as severe weather or technical outages.

Is it time to upgrade your business phone system?
Many companies discover the limitations of their current communication tools when facing pivotal changes such as:

  • Relocating an office or launching a new branch

  • Experiencing rapid business growth

  • Unifying communication systems across multiple locations

  • Dealing with performance issues or failures in a legacy phone system

While these transitions often spark change, the truth is, there’s never a wrong time to evaluate your communications infrastructure. If your current system falls short in reliability, functionality, or scalability, it’s the perfect opportunity to make a smart switch to a modern, unified communications solution that supports your long-term success.

ADC is amazing. They did so much for our business when another provider dropped the ball and provided valuable, proactive solutions that streamlined our business. And they provided a scaleable plan for our future to address the problems of now for IT.

I have worked with Jeff and ADC for over 10 years and their level of service and the way they partner with their clients is such a tremendous asset. As a small business it's hard to handle all things IT within your own organiztion so with ADC they take the hassle out of all of that and have become like an extension of our organization and our team. I highly reccomend to anyone who needs a partner not just another IT company.

My company has been working with Jeff and his team for over 5 years. I have never worked with a company that has such a "can do" attitude. There is nothing that they won't do to help you accomplish your IT goals. There are a smaller organization with big service and knowledge and you can ALWAYS get what you need on a timely basis. I have worked with bigger firms that do not come close to the service from ADC. There have been times where we have been "line down" and we can't work - it is not their fault but they drop everything and get you back up and running. They understand in this world, "You are out of business," if you don't have service. I would HIGHLY recommend Jeff and his team.

Desperately in need of help sorting out old and new systems we found Accredited Data Centers. Within 24 hours Jeff was here at Enterprise Plumbing with a solution and ready to take action. He went back to his team and came up with a seamless and affordable approach to solving our problems. We have never looked back. Jeff, Josh and the team at Accredited Data Centers are our go-to with every IT issue because they answer and offer solutions right away. Their approach is "no hard sell" and we appreciate their professional and capable demeanor. If you're looking for help and/or a true teammate to your business we highly recommend the folks at Accredited Data Centers!

We partnered with ADC after two VERY unsuccessful attempts with other IT companies. Our IT system was an absolute mess, our staff were unhappy, and we were losing revenue. We chose ADC because of their approach. During our initial meetings with Jeff, the owner, and his team, they spent a great deal of time getting to know our company, our needs, and where we were struggling. Just as importantly, they let us know what we should expect from them. And they've delivered on every promise. Nearly immediate resolution of tickets, calls back within an hour or less, and a concrete IT replacement and growth plan that fits in our budget. Within 30 days of partnership initiation, the majority of our day-to-day issues had been resolved. Within 6 months we had become more efficient in our work processes. And at the one-year mark we were saving considerable money on both equipment/subscriptions and IT services. I cannot recommend ADC highly enough. As a fellow business owner, they have taken away one of my biggest ongoing headaches.

I had a fantastic experience with Accredited Data Centers of Sugar Grove, IL. Their quality and response time are truly impressive. From the moment I engaged with them, it was clear that they prioritize customer service above all else. The owner mentioned that they see themselves as a customer service company that does IT, and they genuinely live up to that promise. The team is professional, knowledgeable, and always ready to help with any concerns or issues. I highly recommend Accredited Data Centers for anyone looking for reliable and exceptional IT services.

The MONTGOMERY ECONOMIC DEVELOPMENT CORPORATION, or commonly referenced as the MEDC, reached out to Jeff Corirossi from ADC to see if we could add a system to our conference room that would give us the opportunity to support virtual meetings in a professional atmosphere. Accredited Data Centers evaluated our needs, provided options within our budget, installed and trained us and provided top notch professional staff to get the job done. We couldn’t have asked for a better company to work with. Thank you so much for going way above our expectations! We are so proud to have you as a MEDC member and are thankful for the services you provide to both small and large businesses.
