VoIP Providers & Business Phone Companies in Schaumburg, IL

Express Telephone Systems, Inc. is a business telecommunications company in Schaumburg, Illinois, serving organizations in the northwest Chicago suburbs and beyond. It helps companies choose and set up phone and internet services that fit how they work today and leave room to grow. For buyers comparing VoIP providers, it is a long-established local firm that now focuses on cloud-based calling.

Background and experience

The company was incorporated in Illinois in 1985, so it has worked in business telecom for several decades. Over that time it has moved from traditional phone systems to internet-based communications.

It once held Illinois authority to run customer-owned pay phones and asked the Illinois Commerce Commission to cancel that authority in 2018, a sign that it has left legacy services behind for modern business calling. Listings name owner Marty Therrien and Mike Simon as people associated with the firm.

The company has also been listed in a commercial construction directory since 2014 under communication systems and telephone interconnect work.

VoIP and cloud phone services

The company is an authorized dealer for RingCentral, a well-known cloud IP phone platform. Instead of keeping a phone system on site, clients send and receive calls over their business internet connection. The firm explains this model to businesses that want to simplify their phone setup, and it sees mobility as central to business communications today.

Because staff already rely on smartphones and other mobile devices, a cloud system lets them keep their business phone identity whether they are at a desk, at home or on the road.

Its main offerings include:

• Cloud-based IP phone service as a RingCentral dealer
• Hosted phone service for businesses of different sizes
• Business internet connectivity to support voice traffic
• Network security services
• Software-defined network technology
• Help moving from older phone systems to VoIP

How it works with clients

The firm acts as an advisor and reseller rather than running its own carrier network. It starts by reviewing a company's current phone and internet setup and its expected growth, then recommends services to match. This is useful for businesses that lack in-house telecom staff and want one local contact to handle voice, connectivity and security together.

Since voice quality depends on the internet connection under it, bundling connectivity with hosted calling helps clients get a setup where the pieces work well together.

What sets it apart

Buyers looking at Express Telephone Systems will find a mix of long local roots and a modern cloud offering. A business can work with a Schaumburg-based team that has watched the industry change since the 1980s while using a widely adopted national cloud platform. It suits small and mid-sized organizations in the Chicago area that want a guided move to VoIP, flexible support for mobile workers, and one partner for phones, internet and network security.

Deployment and Ongoing Support

Work typically covers a needs assessment, a site survey, bandwidth testing, quality-of-service management, hardware configuration, setup of user IDs, extensions, conference bridges and ring groups, security configuration, and training.

Once a system is live, customers are assigned a Client Technology Advisor. Support is available at all hours every day of the year, along with proactive account monitoring and routine maintenance and updates.

Industries and Wider Portfolio

The company tailors its offerings to a number of sectors:

• Hospitality, supported by a unified communications platform designed for hotels

A featured customer story comes from Rick Stanbridge, EVP and Chief Information Officer of Marco's Pizza, who credits a custom-designed SD-WAN from S-NET with providing the network base needed to launch franchise-wide systems and support the brand's national growth.

VACK Inc. is a telecommunications and IT infrastructure company headquartered in Schaumburg, Illinois. It describes itself as a specialist in IoT, cloud, optical, wireless and data center services. Voice is one of several traffic types it carries, manages and monitors, alongside data and video. The company suits organizations that want telephony delivered with network transport, Wi-Fi and data center capacity. It is a weaker match for buyers who only want a standalone hosted phone plan.

Communications and Transport

VACK supports both carrier-hosted and customer-hosted arrangements. Its transport portfolio spans voice, internet access, point-to-point and multipoint circuits, broadcast-quality JPEG-2000 video and IPTV. Speeds range from DSL to 100 Gigabit. The company also reviews what a client spends on voice, data and video, and offers cost reduction programs. A round-the-clock operations center watches network and application performance so that uptime is protected.

• Voice, data and video carried over fiber and wireless links
• Round-the-clock network and security operations monitoring
• Managed and hosted Wi-Fi, LTE, LoRaWAN, LAN, WAN, SD-WAN and MPLS
• Lightwave and passive optical networks, including wavelength-division and fiber-to-the-premises designs
• Licensed and unlicensed wireless, in point-to-point and point-to-multipoint form
• Structured cabling design, installation and maintenance

Data Center, Cloud and Site Build

VACK designs, assesses, builds and operates data centers. Its co-location offering is available at sites worldwide, rated from Tier 1 through Tier 4, with large private areas and metered power that can be scaled. Options include multi-tenant, build-to-suit and critical power facility management. The company stresses compliance and security for mission-critical equipment.

Its cloud services target enterprises running hybrid IT, a blend of internal and outsourced systems, and extend to infrastructure, backup, recovery and disaster recovery delivered as services. A separate build practice covers new and existing data center work, power and generation systems, battery backup, cooling, CCTV, access control, AV and low-voltage cabling.

Working Method

Engagements are structured as full implementation programs sized to the project and the client's staff. Typical stages include architecture design, vendor selection, installation, integration, monitoring and life-cycle management. The firm also handles service level agreements, disaster recovery planning, program management for network upgrades, and fiber and system certification.

For wireless projects, VACK combines its own staff with partner engineers in an order-to-install model. Account managers, engineers and certified project managers gather requirements, coordinate with local partners and carry out installations across multiple sites. Planning and predictive site surveys come before deployment.

Target Customers

Its managed WLAN services are pitched at enterprises of every size, with financial institutions, retailers and healthcare providers named as examples that need dependable Wi-Fi for employees and visitors. Security and location analytics are optional. Overall, VACK is best viewed as a multi-service infrastructure partner in which voice is one component, rather than a dedicated VoIP platform vendor.
