FusionPBX vs SRS
A side-by-side editorial comparison of FusionPBX and SRS — release velocity, themes, recent moves, and the top alternatives to consider.
FusionPBX vs SRS: at a glance
What is FusionPBX?
The release feed stops in 2018, so nothing here describes the current product
Every visible entry predates 2019. The newest is 4.4.1, a minor bug-fix release covering call centre login, device password propagation and call detail record naming. Below it sit 4.4.0 with user change logs, call recording management, QR-code provisioning and added translations, and two 4.2.x releases focused on bug fixes and SQL injection hardening in LUA scripts.
What is SRS?
SRS 6.0 went stable by making H.265 work everywhere, not just in one protocol.
SRS shipped 6.0 release 0 in December 2025, promoting the 6.0 line to stable in place of 5.0 at roughly 170,000 lines of code. The headline is H.265/HEVC carried across RTMP, HTTP-FLV, HLS, HTTP-TS and SRT, with DVR recording to both MP4 and FLV. WebRTC gained WHEP for playback, stereo Opus over SDP and a configurable AAC-to-Opus bitrate; SRT moved to libsrt 1.5.3 with round-trip latency reported down to 200ms.

◆ Current state
Every visible entry predates 2019. The newest is 4.4.1, a minor bug-fix release covering call centre login, device password propagation and call detail record naming. Below it sit 4.4.0 with user change logs, call recording management, QR-code provisioning and added translations, and two 4.2.x releases focused on bug fixes and SQL injection hardening in LUA scripts.
◆ Where it's heading
What the archive shows is a project that treated security hardening as release-worthy in its own right and steadily broadened administrative tooling around FreeSWITCH. What it cannot show is anything about the last several years — the feed has been silent since 2018, so no current direction is observable.
◆ Prediction
There is not enough recent data to predict a next move. Until this feed carries releases again, the product's current state is unreadable from here.
SRS
0.0MEETINGS
SRS 6.0 went stable by making H.265 work everywhere, not just in one protocol.
◆ Current state
SRS shipped 6.0 release 0 in December 2025, promoting the 6.0 line to stable in place of 5.0 at roughly 170,000 lines of code. The headline is H.265/HEVC carried across RTMP, HTTP-FLV, HLS, HTTP-TS and SRT, with DVR recording to both MP4 and FLV. WebRTC gained WHEP for playback, stereo Opus over SDP and a configurable AAC-to-Opus bitrate; SRT moved to libsrt 1.5.3 with round-trip latency reported down to 200ms.
◆ Where it's heading
The eighteen months of alpha and beta tags before release 0 were overwhelmingly crash, leak and iterator fixes — smart-pointer conversions, use-after-free repairs in the HLS and bridge paths, RTC-to-RTMP stability. That is the signature of a project stabilizing an existing engine rather than extending it, with the codec work landing at the end. SRS is positioning as the self-hosted streaming server that speaks every ingest and egress protocol in one binary.
◆ Prediction
With 6.0 now the stable line, the pattern from the 5.0 era points to a run of 6.0 patch releases carrying fixes rather than features. The entries give no indication of what the next major line targets.
