3CX

Vendor

3CX is an open-standards business communications platform trusted by over 350,000 companies worldwide that delivers PBX, unified communications, and contact center capabilities in a single integrated solution. Built on SIP and WebRTC standards rather than proprietary protocols, 3CX eliminates vendor lock-in and enables interoperability with standards-based equipment and services. The platform revolutionizes enterprise phone system economics through concurrent-call licensing (not per-user pricing), reducing communication costs by up to 80% compared to legacy proprietary PBX and cloud UCaaS providers while providing unlimited users. 3CX offers flexible deployment—on-premises on Windows/Linux servers, self-hosted in customer data centers or public cloud (AWS, Azure, Google Cloud, DigitalOcean), or managed hosted by 3CX with dedicated instances and SLAs. The company has pioneered simplified PBX administration requiring no telecommunications expertise, making complex phone systems accessible to small IT teams and non-telco administrators through intuitive web-based management interface. 3CX features enterprise-grade AI transcription, sentiment analysis, call summarization powered by OpenAI or Google, optional onboard GPU-based transcription for data sovereignty, and advanced contact center capabilities including skill-based routing, queue management, real-time wallboards, and omnichannel support across voice, SMS, WhatsApp, Facebook Messenger, and website live chat. Platform integrates with Microsoft 365/Teams for directory sync and Teams Direct Routing, popular CRM systems (Salesforce, HubSpot, Zoho), business intelligence tools (Power BI, Grafana), helpdesk systems (Zendesk, Freshdesk), and other enterprise applications via robust API framework. 3CX operates as independent company committed to customer data privacy and security with options for complete on-premises or private cloud deployment ensuring no call data transmission to third parties.
