3CX vs rtpengine: 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 rtpengine?
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
Sipwise's rtpengine media proxy is maintaining several release lines in parallel (mr13.5, mr14.1, mr26.0, mr26.1, mr26.2), and most recent entries are coordinated backports. The September 16 batch fixes hash-table updates, nested string lookups and stop_forwarding mixups across four branches, and adds DTLS negotiation corrections (setup=actpass logic, ignoring incorrect DTLS=passive, keeping TLS IDs on answer role changes) to the mr26.0 and mr26.1 lines.

3CX is opening the PBX to agents while its feed fills with awards and academy news
◆ 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.
rtpengine
5.0MEETINGS
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
◆ Current state
Sipwise's rtpengine media proxy is maintaining several release lines in parallel (mr13.5, mr14.1, mr26.0, mr26.1, mr26.2), and most recent entries are coordinated backports. The September 16 batch fixes hash-table updates, nested string lookups and stop_forwarding mixups across four branches, and adds DTLS negotiation corrections (setup=actpass logic, ignoring incorrect DTLS=passive, keeping TLS IDs on answer role changes) to the mr26.0 and mr26.1 lines.
◆ Where it's heading
The work is focused on correctness in media negotiation, especially DTLS role handling and ICE on closed sockets, rather than new features. The newest branch, mr26.2, also brought AMR fmtp defaults, mirroring of generated RTCP sender reports to Homer, and recording cleanup hardening, which points to better interop and observability for carrier deployments.
◆ Prediction
More synchronized backport releases across the mr13.5 through mr26.2 lines are the clear pattern; feature work will most likely keep landing on mr26.2 first.
