More About Quantcom
Quantcom is a telecommunications and ICT services provider headquartered in the Czech Republic, operating under the Quantcom and Dial Telecom brands and addressing enterprise, public sector, and carrier customers. Its portfolio centers on fixed data connectivity, voice services, cloud infrastructure, and data center and managed services, which are built on its own backbone network and facilities. The company positions its solutions for organizations that require stable connectivity, predictable service-level commitments, and integration with broader ICT architectures rather than consumer-grade access.
In networking, Quantcom provides fixed internet access and point-to-point or point-to-multipoint data services (networking) built on Ethernet, Multiprotocol Label Switching (MPLS), and IP technologies. These offerings are designed for corporate WANs, branch connectivity, and wholesale backhaul for other operators. Enterprises use these services to interconnect headquarters, data centers, and regional offices with defined bandwidth, latency, and redundancy characteristics. Carriers and ISPs can use Quantcom’s backbone for transit or last-mile access, integrating it into their own IP/MPLS networks.
Quantcom’s voice portfolio (unified communications) includes Session Initiation Protocol (SIP) trunking and other IP telephony options, typically integrated with customers’ PBX systems or UC platforms. These services rely on Voice Over Internet Protocol (VoIP) protocols such as SIP and Real-time Transport Protocol (RTP), and can coexist with legacy ISDN or TDM environments during migration. Enterprise telephony deployments may use Quantcom’s services for both domestic and international calling, number hosting, and interconnection with the public switched telephone network (PSTN), with routing configured to align with corporate dial plans and security policies.
In cloud infrastructure, Quantcom operates its own virtual data center and cloud services (cloud infrastructure), where customers can deploy virtual machines and related resources instead of or alongside on-premises (on-prem) infrastructure. These services typically use virtualization technologies and standard hypervisor platforms, enabling enterprises to host business applications, databases, and internal services within Quantcom’s facilities. This model appeals to organizations that prefer regional data residency and direct connectivity from their existing Wide Area Network (WAN) links rather than hyperscale public cloud-only models.
Quantcom also offers colocation (data center services) in its data centers, providing rack space, power, cooling, and physical security for customer-owned servers, storage, and networking equipment. Customers often combine colocation with Quantcom’s backbone connectivity to build hub sites, Disaster Recovery (DR) locations, or hosting for latency-sensitive workloads. Managed services (managed services) layer on top of these infrastructures, covering network operation, monitoring, and support, allowing organizations to offload part of their ICT operations while retaining architectural control. In a directory or marketplace, Quantcom fits into categories such as enterprise connectivity, carrier services, cloud infrastructure, data center colocation, and managed network and ICT services.
