sipXcom review
A capable open-source SIP platform for teams prepared to manage Linux infrastructure.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
sipXcom is an open-source unified communications and IP PBX platform for organizations ranging from small installations to large enterprises. It is aimed at technical teams that need control over SIP infrastructure, call routing, phone provisioning, voicemail, conferencing, and administration. The platform supports multiple business numbers, auto attendants, custom call routing, and deployment through cloud or self-hosted environments. Its browser-based administration and user portals provide a web interface, while REST and SOAP interfaces support integration with other systems.
Its main strength is breadth within core telephony. sipXcom covers SIP session routing and trunking, multi-level auto attendants, dial-by-name and extension transfer, voicemail with email notifications, hunt groups, call queues, conferencing, and call recording. Custom dial plans can use time-based, permission-based, and least-cost routing. Provisioning for phones and gateways adds administrative coverage, and support for SIP-compliant devices and third-party softphone clients broadens its ecosystem fit. Integrations include Microsoft Active Directory, Microsoft Exchange, IMAP-compatible mail systems, Openfire/XMPP, FreeSWITCH, Jitsi, CounterPath Bria, and SIP-compliant gateways.
The trade-off is operational responsibility. sipXcom is deployed on customer-managed Linux servers, either as a single server or as a distributed and optionally redundant cluster, so it suits organizations with the technical capacity to maintain that environment. Support is centered on community resources and documentation rather than a listed commercial support structure. The offering also focuses on open-source SIP and PBX capabilities rather than mobile applications, AI assistance, or transcription. Choose sipXcom when infrastructure control, extensible routing, and open-source deployment matter most; teams seeking a managed phone service or a broader mobile-first feature set should consider alternatives.
