Voipfone

Voipfone operates as a United Kingdom‑based provider of Voice over Internet Protocol (VoIP) communications, delivering telephony services over IP networks rather than traditional circuit‑switched infrastructure. Its core product suite includes voice calling, short message service (SMS) and both inbound and outbound telephony capabilities that are accessed through the company’s platform. The service is aimed at business customers who require reliable voice and messaging connectivity for daily operations, customer support and internal collaboration. By hosting its own switching and media gateways, Voipfone can offer features such as call forwarding, voicemail, call recording and conference bridging without relying on legacy telephone company equipment. The platform is positioned as a scalable, internet‑based alternative to legacy PBX systems, allowing organisations to add or remove lines and adjust capacity through software‑driven provisioning. Although the exact number of subscribers or revenue figures are not disclosed in the available sources, the provider is known to serve a variety of sectors that depend on uninterrupted voice communication, including retail, hospitality and professional services.

Voipfone’s profile is notably shaped by its experience with coordinated extortion‑driven Distributed Denial of Service (DDoS) attacks, which have been documented in two separate incidents during 2021. The October 22, 2021 attack involved a sustained flood of malicious traffic that overwhelmed the provider’s network infrastructure, resulting in multi‑day outages of voice services and preventing customers from placing or receiving calls. During that incident, users reported communication gaps and an inability to implement failover solutions, highlighting the reliance of many businesses on Voipfone’s continuous availability. An earlier attack on August 31, 2021 was attributed to the REvil ransomware group and produced intermittent disruptions affecting voice calls, SMS messaging and both inbound and outbound telephony despite partial restoration attempts. These events placed Voipfone within a broader international extortion campaign targeting multiple telecommunications providers, prompting the company to engage with the UK Comms Council, industry peers and law‑enforcement agencies to develop mitigation strategies. The response included temporary platform failures, prolonged recovery work and the implementation of traffic‑filtering and bandwidth‑scrubbing measures coordinated across the sector, while no explicit details about Voipfone’s ownership, parent company or subsidiary structure are provided in the supplied material.
