What sipXcom is
sipXcom, also documented as sipXecs, is open-source unified communications software built around SIP routing and PBX services. It combines traditional phone systems with instant messaging and video calling. Its listed PBX functions include voicemail, unified messaging, auto-attendant, conferencing, presence and call-center capabilities, alongside custom call routing and multiple business numbers.
The software can run on one server or across a distributed system, with optional redundancy. A web management application centralizes configuration, including across distributed deployments, and supports plug-and-play setup for phones and gateways. The project targets small to mid-sized enterprises, from a few users to several thousand. Web service APIs, including REST and SOAP, can connect internal user-management systems and other applications.
sipXcom runs on standard Intel x86 Linux servers and uses external gateways rather than special voice cards. Installation documentation covers Fedora and CentOS; the listed version 21.04 ISO specifies CentOS 7. Any SIP-compatible phone can be configured manually, while several models are identified for plug-and-play management. Security capabilities include authenticated outbound calls, password management, denial-of-service prevention, HTTPS access and TLS signaling for SIP trunks.
Who it suits
sipXcom suits small and mid-sized enterprises that need PBX communications alongside messaging and video calling, with deployment options from one server to a distributed system. It may also suit teams that want to connect user-management systems or other applications through its web service APIs.
