3CX vs SRS: 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 SRS?
SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.
SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.

◆ 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.
SRS
6.3MEETINGS
SRS opens a 7.0 line built on a Go proxy tier, and drops features it no longer wants to carry.
◆ Current state
SRS shipped the stable 6.0 line's first release on 12 August and, three hours later, the first development build of 7.0. The 6.0 line is now in pure maintenance — the r1 changelog is seven merges of DVR, WebRTC and edge fixes. Everything new is in 7.0-d0: RTSP playback, RTMPS, IPv6 across every protocol, HEVC in both directions between RTMP and WebRTC, and HLS fMP4 segments for HEVC and LL-HLS.
◆ Where it's heading
The project is trading breadth of legacy surface for a narrower, better-covered core. 7.0-d0 removes the embedded GB28181 SIP server, multi-threading, Cygwin, and most configuration hot reload, while introducing a Go proxy server and origin-cluster architecture alongside the C++ media core. Protocol coverage keeps generalizing — each release makes a codec or an address family a property of the server rather than of one delivery path.
◆ Prediction
Expect the 7.0 line to run a long alpha and beta train the way 6.0 did, with the Go proxy and origin clustering carrying most of the remaining work and 6.0 continuing to receive backported fixes in parallel.
