A side-by-side editorial comparison of Element Call and rtpengine — release velocity, themes, recent moves, and the top alternatives to consider.
Element Call drops MatrixRTC legacy mode entirely, betting the entire call stack on the multi-SFU protocol.
Element Call is deep into a protocol transition: MatrixRTC legacy mode was removed in v0.25.0-rc.1, and .well-known transport discovery was removed in v0.24.0-rc.1. Both had been optional for months before the forced cutover. The current v0.26.x RC cycle is stabilizing the post-legacy stack with bug fixes to audio output selection, memberId handling in MatrixRTC mode, and leave timing adjustments when SFU delegation is active. The product ships exclusively as release candidates at this stage, signaling it's in final pre-release hardening.
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.

The product ships exclusively as release candidates at this stage, signaling it's in final pre-release hardening.
Having removed both legacy transport paths, Element Call is fully committed to a multi-SFU architecture where each homeserver operator runs their own SFU and participants connect to whichever SFUs host the streams they need. The ongoing RC cycle and the LiveKit logging improvements in v0.26.0-rc.1 point to a push for call-quality diagnostics before a stable release. Mobile performance has been a consistent focus across v0.22–v0.26 — landscape layouts, PiP mode, voice-only call handling — pointing to mobile as a priority segment.
A stable v0.26.0 release is imminent given the RC cadence. The delegated leave timing breaking change in v0.26.0-rc.2 is unfinished infrastructure for SFU delegation — that work will likely define the next development cycle.

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.
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.
