RJ2 Technologies is a managed IT provider in Deer Park, Illinois that has designed, installed and supported business phone systems for companies across Chicago and the Chicago suburbs since 1998. We assess what your offices actually need, recommend a VoIP platform, port your existing numbers, configure call flow and voicemail, and then support the system as part of your IT service rather than handing you off to a carrier support line. Because we already manage the network the phones run on, a call quality problem does not turn into an argument between two vendors. Most clients move to VoIP to cut line costs and to let people take their extension home or to a second office.

What is a VoIP phone system, and how is it different from what we have now?

VoIP carries calls over your internet connection instead of over dedicated phone lines, so the phone system lives in software rather than in a box in a closet. In practice that means you stop paying per line, extensions follow people to a laptop or a cell phone, and adding a user is a configuration change rather than a service call.

The tradeoff is that your phones now depend on your internet connection and your network, which is why the network assessment comes before the phone recommendation, not after. An office with a single unmanaged internet circuit and a consumer-grade switch will have call quality problems on any platform.

Which VoIP platforms does RJ2 support?

RJ2 recommends and supports a business VoIP platform based on what your offices need, and can take over support for a system you already own rather than forcing a replacement. Which platform fits depends on how many users you have, whether you need contact center features, and whether you are already standardized on Microsoft 365.

RJ2’s primary platform is SkyCom, its own white-labeled hosted phone service, which has an optional Microsoft Teams integration. RJ2 also partners with third-party providers, including Mitel, CoreDial, 8×8, Nextiva and Google.

Can we keep our existing phone numbers?

Yes. Existing numbers port to the new system, including your main published number and direct dials, and porting is a standard part of the cutover rather than an extra project.

Porting is a carrier-side process with a lead time, so it gets scheduled before the install date and the old service stays live until the port completes. Nobody loses calls on the changeover day.

What happens to our phones if the internet or power goes out?

Calls to your main number keep being answered, because the call routing lives in the cloud rather than in your building. When a site loses connectivity, inbound calls fail over to a rule you set in advance, most commonly forwarding to cell phones, to another office, or to voicemail with an automated notification.

That failover has to be configured deliberately before it is needed. RJ2 sets it up during implementation and it is one of the things worth re-testing annually.

Does a VoIP system integrate with Microsoft Teams?

A VoIP phone system can work with Microsoft Teams, and the right setup depends on how your organization already uses Microsoft 365. RJ2’s usual approach is SkyCom’s Teams integration, which runs as a softphone inside Teams. That gives more flexibility in how calling is deployed and lets RJ2 control and support the whole experience.

What else comes with unified communications besides calling?

Unified communications means voice, video conferencing, instant messaging and file sharing running on one platform under one login instead of four separate tools with four bills. The practical benefit is that a chat becomes a call becomes a screen share without anyone changing applications or sending a meeting link.

What is typically included:

  • Voice calling, extensions, auto attendant and voicemail to email
  • Audio and video conferencing
  • Instant messaging between staff
  • Secure file sharing inside the same platform
  • Adding or removing users without a service visit, which is what the live page means by scalability
  • Call reporting

Does RJ2 install phone systems in Chicago and the Chicago suburbs?

Yes. RJ2 is headquartered at 21660 W. Field Parkway, Deer Park, IL 60010, and installs and supports business phone systems throughout Chicago and the Chicago suburbs.

On-site work, including handset deployment, cabling checks and network remediation before a cutover, covers the Chicagoland area, and RJ2 also serves Rockford and northern Illinois, southeastern Wisconsin, and northwestern Indiana, with nationwide support for larger clients that have multiple locations. Engineers working downtown use a drop-in space at 333 S. Wabash Ave., Suite 2700. It is a working space, not a staffed office.

Multi-site companies are the common case here. One phone system across several suburban offices, with four-digit dialing between them, is usually the reason a company calls in the first place.

How do we get started?

Book a discovery call, or call 847-303-1194. The first step is an assessment of your current phone setup, your contract end dates and your network, because the network is what determines whether VoIP will work well in your building.

Frequently asked questions

Who installs VoIP phone systems for Chicago businesses?

RJ2 Technologies installs and supports business VoIP phone systems for companies in Chicago and the Chicago suburbs, and has worked in Chicago-area IT since 1998. We handle the assessment, the platform recommendation, number porting, configuration and ongoing support. The company is headquartered in Deer Park, Illinois.

How much does a VoIP phone system cost for a small business?

Cost depends on the number of users, whether you need desk phones or softphones only, and which platform fits, so it is quoted after an assessment. Most companies moving off traditional lines are comparing against what they pay per line today, which is the right comparison to bring to the call.

Can we keep our phone numbers if we switch to VoIP?

Yes. Your existing numbers port to the new system, including your main number and direct dials. Porting is scheduled ahead of the install and your old service stays active until the port completes, so no calls are dropped during the transition.

What happens to our phones during an internet outage?

Because call routing lives in the cloud rather than in your building, inbound calls fail over to a rule configured in advance, usually forwarding to cell phones, another office, or voicemail. That rule has to be set up before it is needed, which is part of implementation.

Does VoIP work with Microsoft Teams?

A VoIP system can integrate with Microsoft Teams, and the right approach depends on how your organization uses Microsoft 365. RJ2’s usual approach is SkyCom’s Teams integration, which runs as a softphone inside Teams. That gives more flexibility in how calling is deployed and lets RJ2 control and support the whole experience.

Is VoIP reliable enough for a business that lives on the phone?

Call quality on VoIP is a network question more than a platform question, which is why an assessment of your internet circuit, switching and wireless comes before any recommendation. Businesses that depend heavily on inbound calling should also plan a backup path for connectivity.

Can one phone system cover multiple offices?

Yes. A single VoIP system covers several locations with extension dialing between offices, one directory and one auto attendant, which is usually simpler and cheaper than separate systems per site. This is a common reason Chicago-area companies with suburban branch offices move to VoIP.

Do you support the phone system, or do we call the carrier?

You call the RJ2 support line at 847-303-1193. Because we manage the network the phones depend on, we can look at both sides of a call quality problem rather than handing you between two vendors.
