2Cx

2CX is a Windows-based IP Private Branch Exchange (PBX) software solution for voice over IP (VoIP) communications. Developed by 2CX Ltd, the product provides telephony features for small to medium-sized businesses by routing calls between SIP-compatible endpoints and the traditional phone network.

Historically, 2CX has been positioned as a cost-effective alternative to traditional PBX systems and open-source platforms, offering an easier installation on Windows servers and a centralized web-based management interface. The software supports common VoIP standards and integrates with SIP-based phones, soft clients, and gateways to connect to PSTN networks.

Key features include automated attendant (IVR), call routing and queues, voicemail and voicemail-to-email, call recording, presence information, conferencing, call reporting and analytics, and mobile client support. It also includes management tools for configuring extensions, call paths, and security settings, plus scalability options for growing businesses.

2CX runs as a Windows service on supported server editions and can be deployed on-premises or in hosted environments with remote management via a web console. It supports integration with gateways and SIP trunks, enabling connectivity to public networks and enterprise telephony infrastructure. The licensing model is commercial, with options that typically cover perpetual or subscription-based use depending on version and deployment.

Due to its Windows-centric design, 2CX has been popular among SMBs seeking an easier-to-manage alternative to Linux-based PBX platforms, though adoption has varied by region and organization. Users typically evaluate compatibility with their existing hardware, desired unified communications features, and total cost of ownership when considering 2CX as a telephony platform.
