rtpengine
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
A side-by-side editorial comparison of 3CX and coturn — release velocity, themes, recent moves, and the top alternatives to consider.
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.
coturn ships three minor versions in six weeks, packaged as Docker images on three registries.
The tracked feed for coturn, the open-source TURN/STUN server, is Docker image releases: 4.16.0, 4.17.0, 4.17.1, 4.17.2 and 4.18.0 between late July and early September 2026. Each is published to Docker Hub, GitHub Container Registry and Quay.io, and the release notes here point to the upstream changelog without listing changes.

Around them sit a G2 badge announcement, an academy launch and a walkthrough for adding a customer service AI agent to an existing setup.
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.
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.
The tracked feed for coturn, the open-source TURN/STUN server, is Docker image releases: 4.16.0, 4.17.0, 4.17.1, 4.17.2 and 4.18.0 between late July and early September 2026. Each is published to Docker Hub, GitHub Container Registry and Quay.io, and the release notes here point to the upstream changelog without listing changes.
The cadence picked up: three minor versions (4.16, 4.17, 4.18) landed in about six weeks, with two same-day patch images for 4.17. The project keeps container packaging in lockstep with upstream releases, which matters to operators running TURN for WebRTC in containers.
A 4.18.x patch image or a 4.19.0 release is the likely next entry, following the observed roughly two-to-four-week rhythm; the feature content is not visible from these entries.
