VoIP Providers & Business Phone Companies in Marietta, GA

Botwin Communications is a low-voltage and telecommunications contractor based in Marietta, Georgia. It has served business customers since 1994. The firm aims to be the one vendor for the systems that keep an office connected and secure. It installs business telephone systems and also handles structured cabling, wireless networking, video surveillance, access control and meeting room automation. Its clients range from start-ups and small companies to Fortune 500 organizations across metro Atlanta and the wider Southeast.

Voice and communications services

For buyers comparing phone vendors, Botwin is best seen as an installer of business phone systems, not a hosted-only provider. The company designs and installs office phone platforms and supports call center environments. It also sets up wireless SIP handsets so staff can be reached anywhere in a building. The same team runs the copper and fiber that carry voice and data traffic, so the phone system and the network underneath it can be planned together. This can cut down on the disputes that sometimes come up when several contractors share one project.

• Business phone system design and installation
• Wireless SIP handsets and mobile communications integration
• Call center system support
• Voice and data cabling, including fiber optic
• Enterprise Wi-Fi design and management
• IP and CCTV video surveillance
• Access control using cards, fobs and biometrics
• Conference room automation
• Service agreements and extended equipment warranties

How the company works with clients

Projects begin with a free consultation and follow four stages. In the study stage, Botwin works out which features a client actually needs and which can be left out. In the design stage, the team builds a system around those needs and the conditions at the site. Certified installers then put the system in and test it against manufacturer specifications and the firm's own internal checks. At launch, the team walks users through the finished system and leaves training materials for later reference.

Beyond voice, Botwin's cabling technicians build custom cables on site for voice and data use. They are often called in to diagnose network faults and to tidy up crowded server and computer rooms. The wireless practice also covers barcode and RFID scanning and mobile computing, which may suit warehouses, distribution centers and other businesses that rely on handheld devices. On the security side, the company installs cameras that can be viewed remotely or on a smartphone, offers optional offsite monitoring, and puts in door access systems that can grow with the business.

What sets Botwin apart

Botwin's main strength is consolidation. A business can hand telephony, cabling, Wi-Fi, surveillance and access control to one contractor with a single point of contact. The company points to long-term customer relationships, projects delivered on schedule and ongoing support through service agreements after installation. It is a good fit for Marietta and greater Atlanta organizations that want a local installer for an office phone system, especially as part of a larger infrastructure build-out or office move. It is less suited to buyers who only want a standalone cloud phone subscription.

Conquest Solutions is a technology firm in Marietta, Georgia, and has worked with companies across Metro Atlanta since 2004. It handles telecommunications, managed IT, cybersecurity, physical security and low-voltage cabling, so an organization can give its phones, network and building systems to a single responsible provider. It is certified as a women-owned company (WBE and WOSB) and reports a 97 percent customer satisfaction rating.

Business phone and VoIP offerings

On the telecom side, Conquest plans, installs and manages cloud-based calling for businesses that want to move off older phone setups. Its main platform is 3CX, which the company is certified to deploy. A system can run in the cloud, on premises or as a hybrid, and it is sized to the number of seats a client really uses. Each user gets one extension that works on a desk handset, a desktop application and an iOS or Android app. That lets staff take calls, check voicemail, chat and transfer callers while away from the office. Video and unified messaging are part of the platform.

• Hosted VoIP calling for office, remote and mobile staff
• Unified communications combining voice, chat, video and voicemail
• 3CX consulting, implementation, migration and ongoing management
• Business internet sourcing, bandwidth sizing and circuit management
• Telecom audits of carriers, plans and individual lines
• Planning to replace copper POTS lines used by alarms, elevators, fax and card terminals

How projects are handled

A project usually starts with a review of the client's current phone and internet invoices. The team looks for seats nobody uses, overlapping carriers and outdated maintenance agreements. It then designs a 3CX setup that fits how the staff works, moves the existing numbers over, configures E911 and times the cutover to limit disruption during business hours. After launch, the engineers who installed the system also handle updates, new users and call-flow changes. Clients can often keep their current handsets, and some teams use only the software apps.

What sets the company apart

Conquest also manages its clients' networks and internet circuits, so voice is not sold as a separate product. The firm sets up bandwidth with call quality in mind and builds the network underneath itself. That means a dropped call does not become an argument between a carrier and a separate phone vendor. Its infrastructure crews install and certify copper Cat6, fiber and backbone riser runs. Its IT practice provides flat-rate managed services, help desk support, backup and disaster recovery from engineers based at the Marietta headquarters.

Outside of phones, the company protects HOAs and gated neighborhoods, office and multi-tenant buildings, apartment properties and senior-living campuses. It does this with access control, video surveillance, gate systems and license plate recognition. It sells two products of its own: Conquest LPR, which opens gates based on license plates, and Charlotte, which sends real-time door alerts. It also works as an ongoing site-design partner for senior-living communities. On-site installation is mostly in Metro Atlanta, while camera, network and monitoring work can reach locations across the country. Businesses do not have to sign a long-term agreement to work with the firm, because it also takes on one-off jobs.

InfoTank is a Marietta, Georgia, provider of outsourced technology management and cyber defense. Owned by a military veteran, the firm focuses largely on professional services organizations throughout the greater Atlanta region. Its core role is serving as a company's external technology team. Organizations weighing their telephone choices can also turn to InfoTank for hosted voice and internet circuit management, which allows them to place calling, data, protection and day-to-day assistance under a single responsible provider.

Voice and Internet Management

Rather than operating a carrier network of its own, InfoTank works with third-party broadband providers and voice platform vendors, bargaining on behalf of the businesses it serves. The firm then handles deployment and configuration itself. Its goal is to eliminate the garbled sound, cut-off conversations and unreliable links that can derail client calls and drain income. Every voice and circuit arrangement is tailored to the specific organization. InfoTank's round-the-clock threat surveillance extends to these communication links as well.

• Hosted telephone service delivered across internet connections
• Choosing, procuring and maintaining broadband providers
• Management of deployment and communication with suppliers
• Safeguards for calling and data infrastructure

Full Technology Portfolio

Voice and broadband sit within a much larger outsourced technology bundle. This covers user assistance, preventive upkeep, system health tracking, network administration and equipment supply. Additional areas include moving workloads to the cloud, off-site data copies, continuity and recovery strategy, Microsoft 365, website building and internal portal projects. For protection, InfoTank provides device-level threat detection and remediation, junk mail screening, perimeter firewalls and encrypted remote access, employee awareness education, and assistance meeting CMMC requirements. The company has recently expanded into AI-driven automation that links software platforms and simplifies routine processes. According to InfoTank, enterprise-grade protective tools come built into its base offering instead of being billed separately, and executive-level technology strategy and budget advice from a virtual CIO is bundled in too.

Client Engagement Approach

InfoTank reports that incoming calls are picked up within roughly fifteen seconds. Help is delivered by experienced engineers familiar with each customer's systems, and the firm states its technical staff average around two decades in the field. By accepting responsibility for every layer of a client's technology, it avoids the finger-pointing that happens when multiple suppliers are involved. Organizations with in-house technical employees can opt for a shared-responsibility arrangement. Newly signed customers receive a ninety-day trial window with no risk, and the firm will assist in exiting a current provider agreement. Coverage is available at any hour regardless of time zone, and InfoTank supports distributed staff and companies with several locations nationwide.

Leadership and Track Record

The company is headed by Managing Partner Matt Canavan, an alumnus of The Citadel who served in the U.S. Air Force. InfoTank cites roughly a quarter century of operating history and says 98 percent of its customers stay with it. On Google, it carries a perfect five-star score from upward of one hundred reviewers. Its customers have expanded from five-person offices to workforces exceeding five hundred. In 2026, a regional recognition program placed InfoTank among twenty-five standout smaller companies in the Atlanta metro. Its team is based locally, with no overseas staffing or independent freelancers. The firm is a strong fit for organizations that prefer to have hosted calling handled within a complete technology and protection program rather than purchased as a standalone service.

Overview

Integral Choice is a technology brokerage in Marietta, Georgia. It helps organizations choose and buy voice, data and cloud services from established carriers. The firm does not run its own network. Instead, it works as an independent agent, matching each client with options from more than 65 providers, including Verizon, AT&T, CenturyLink and Comcast. The company has been in business since 2004 and serves customers nationwide. Its site has location pages for Atlanta, Savannah, Chicago, Orlando, West Palm Beach, Utah and Virginia.

A main focus of its work is moving businesses off older phone equipment and onto hosted voice and cloud contact center platforms built on IP technology. For buyers comparing VoIP options, this means one advisor can lay out cloud calling, unified communications and connectivity packages from several carriers side by side. The buyer doesn't have to get a separate quote from each vendor.

VoIP and unified communications

Its unified communications (UCaaS) offering pairs cloud-hosted VoIP calling with messaging and collaboration tools. Features available through its carrier partners include:

• Virtual PBX and hosted business phone systems
• Hosted interactive voice response (IVR)
• Instant messaging and presence indicators
• Mobility tools for staff working away from the desk
• Unified messaging and email management
• Web, voice and HD video conferencing
• Fax-to-email
• Unified communications hardware

The company treats UCaaS as an operating cost rather than a large upfront capital purchase. It points out several advantages:

• Users and features can be added or removed quickly as headcount changes.
• Hosted platforms run in off-site data centers with built-in redundancy.
• Disaster-recovery-as-a-service can be added to a phone deployment to keep the business running during outages.

Per-user billing across all locations is also described as a way to simplify administration.

Connectivity and broader IT

Call quality depends on the network underneath it, so Integral Choice also sources business internet, bundled phone and data plans, and multi-site WAN and SD-WAN solutions. The carriers it highlights include:

• GTT
• NiTel
• Comcast
• Spectrum for Business
• Windstream
• CenturyLink
• Verizon
• One Ring Networks, which provides fixed wireless access in the Atlanta and Dallas-Fort Worth areas

Beyond telecom, the firm offers cloud solutions, managed services, remote work enablement and customer experience programs. It also offers digital transformation consulting that covers technology choices, staff skills, workplace culture, AI-driven automation, process standardization and performance metrics.

How it works with clients

Integral Choice's business model is meant to cost the customer little or nothing. The agency is paid by the carriers it represents as clients pay their regular monthly bills, so nearly all of its advisory work carries no fee. The company says this gives it an ongoing stake in client satisfaction after installation. It describes its role as cutting telecom spending and saving owners the time it takes to research providers themselves. Prospective customers can start by requesting a free quote, and staff are available to talk through voice, data, cloud and network security needs.

Navious Technologies is a managed IT provider based in Marietta, Georgia. It supports small and mid-sized organizations across metro Atlanta and north Georgia, and it offers business VoIP phone systems as part of a wider technology services portfolio. The firm says it is best suited to companies with roughly 10 to 100 employees. For buyers comparing business phone companies, Navious is not a standalone phone carrier. It is an IT partner that handles voice communications together with networks, cloud tools, security and backups.

VoIP Phone Systems

Navious designs VoIP setups around the way each client already communicates, so the systems are not off-the-shelf packages. The work covers the whole life of a phone system. That starts with planning and installation and continues through integration with the client's existing IT environment, staff training and ongoing management. The company says it aims to keep downtime low during the switch from older phone lines. Its phone systems are also covered by the same around-the-clock monitoring it uses for the rest of a client's infrastructure. Because one team manages both the phones and the network they run on, clients have a single point of contact when call quality or connectivity issues come up.

Industries and Specialties

The company focuses mainly on architecture, engineering and construction (AEC) firms. Its staff know the design applications those firms use every day, including AutoCAD, Revit, Bluebeam, SketchUp and Enscape. Navious also lists other sectors it serves:

• Architecture, engineering and construction
• Medical practices
• Legal firms
• Manufacturing

Broader IT Services

Besides voice, Navious can act as a client's in-house IT department. Its services include managed IT, outsourced support, cloud migration and management, cybersecurity, data backup and recovery, disaster recovery planning, IT compliance and Office 365. On the security side, it offers firewalls, intrusion detection, multi-factor authentication, vulnerability scans and guidance on regulations such as HIPAA and PCI-DSS. The firm sets standard workstation configurations for each role and keeps written records of system settings. It also produces technology roadmaps that look one to three years ahead, so clients can plan hardware and software spending.

How They Work With Clients

New clients usually start with a short discovery call to find the main problems in their current setup. Navious then reviews the existing technology and delivers a plan in three phases, after which it takes over day-to-day management. The company reports an average response time of about three and a half minutes and promotes a no-small-print guarantee. It says it explains technical choices in plain language and ties them to business results.

Background and Coverage

The office on West Oak Parkway in Marietta serves a wide area of north Georgia. Communities on its service list include Atlanta, Alpharetta, Kennesaw, Roswell, Smyrna, Sandy Springs, Canton, Cartersville, Cumming, Duluth, Gainesville, Johns Creek, Lawrenceville, Peachtree City, Rome, Dawsonville and Ellijay. Marietta-area businesses looking for a local provider that handles VoIP together with full IT support may find this combined approach useful.
