3CX vs OpenSIPS: at a glance
What is 3CX?
3CX is opening the PBX to agents while its feed fills with awards and academy news
3CX is a self-hosted business phone system, and its feed mixes real releases with marketing. The releases have been solid and specific: an MCP server for managing the PBX from an AI client, a choice of SendGrid or Zoho for system email, department-level music on hold. Around them sit a G2 badge announcement, an academy launch and a walkthrough for adding a customer service AI agent to an existing setup.
What is OpenSIPS?
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.

◆ Current state
3CX is a self-hosted business phone system, and its feed mixes real releases with marketing. The releases have been solid and specific: an MCP server for managing the PBX from an AI client, a choice of SendGrid or Zoho for system email, department-level music on hold. Around them sit a G2 badge announcement, an academy launch and a walkthrough for adding a customer service AI agent to an existing setup.
◆ Where it's heading
The AI thread is the one with direction. An MCP server for the PBX makes administration something an assistant performs rather than a console task, and the customer-service agent guide extends the same idea to the call path itself. The rest is steady administrative polish — email provider choice, per-department hold music — which is what a self-hosted product ships between larger moves. The award and academy posts carry no product content and should not be read as cadence.
◆ Prediction
With an MCP server for administration and a documented path for a customer service agent, the obvious gap is the two meeting — call handling driven by the same MCP surface rather than a separately configured agent.
OpenSIPS
0.0MEETINGS
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
◆ Current state
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
◆ Where it's heading
The product is moving toward a 4.0 major release through a standard RC cycle. A second RC a month after the first suggests stabilization work rather than new scope, but the entries do not say what 4.0 changes.
◆ Prediction
A 4.0.0 general release is the next expected step; what it contains cannot be read from these announcements.
