What Excalibur Communications does

Excalibur Communications is a UK-based B2B telecommunications and managed IT services provider founded in 1993 and headquartered in Swindon, England. Following its March 2024 acquisition by Onecom Group, the entity now operates under the Onecom brand while retaining its local operations and team structure. The company delivers a comprehensive portfolio spanning business mobile contracts, unified communications (Connect4Teams Microsoft Teams Direct Routing, Onecom Vox, Hosted VOIP, Zoom Phone), cloud contact centre solutions (CCaaS, AI Contact Centre, Five9, Zendesk, Zoom Contact Centre), business connectivity (Full Fibre Ethernet, SD WAN/SASE, Business IoT), and managed IT services (PenX, Onecom CyberProtect, Cloud Backup, Security Awareness Training). Its flagship proprietary platform is Halo, a managed AI Agent Workforce positioned as an autonomous agent layer that scales on demand and improves over time.

The company serves three primary customer segments: enterprise businesses requiring comprehensive mobility, UC, and managed IT deployments; small and medium enterprises seeking cost-effective mobile and connectivity solutions; and the UK public sector accessed through established procurement frameworks. Revenue is generated predominantly on subscription and managed-services contracts (recurring), with pricing determined per quote rather than through published tiers. Go-to-market combines direct enterprise and SME field sales, a partner/reseller program (onecompartners.co.uk), an e-commerce storefront (shop.onecom.co.uk), and a dedicated public sector sales unit. Technology integrations with Microsoft, Zoom, Five9, Zendesk, Aruba (HPE), Samsung Knox, and TeamViewer anchor the stack, and the company holds ISO 27001, ISO 22301, and Cyber Essentials certifications that support regulated and public-sector tenders.
