mediasoup vs FreeSWITCH: at a glance
What is mediasoup?
mediasoup's Rust line is absorbing an outside security audit while finishing subchannels over pipe transport.
The Rust crate has shipped eight releases in five weeks, all of them worker-level. Two threads run through them: a set of memory-safety and cryptographic fixes credited to an external reporter, covering constant-time comparison in SCTP state-cookie and STUN message-integrity verification, an out-of-bounds write in RTP dependency-descriptor handling, and an integer overflow in SCTP error-cause parsing; and the subchannels mechanism being extended to pipe transport, encoded in 0.23.0 and completed for pipe DataConsumers in 0.24.2. SVC was also enabled for VP8 and H264 along the way.
What is FreeSWITCH?
After twenty-one months of silence, FreeSWITCH 1.11 deleted thirty legacy modules and moved on
The 1.11 line arrived in May 2026 after the 1.10 series had gone quiet since August 2024. Its opening release migrated to PCRE2, upgraded Windows to OpenSSL 3.x, added Debian 13 support and removed roughly thirty legacy modules. The follow-up three weeks later added a reloadcert API for hot TLS certificate reloads across mod_sofia and mod_verto without dropping calls, plus SIP 603 detection and passthrough control.

mediasoup's Rust line is absorbing an outside security audit while finishing subchannels over pipe transport.
◆ Current state
The Rust crate has shipped eight releases in five weeks, all of them worker-level. Two threads run through them: a set of memory-safety and cryptographic fixes credited to an external reporter, covering constant-time comparison in SCTP state-cookie and STUN message-integrity verification, an out-of-bounds write in RTP dependency-descriptor handling, and an integer overflow in SCTP error-cause parsing; and the subchannels mechanism being extended to pipe transport, encoded in 0.23.0 and completed for pipe DataConsumers in 0.24.2. SVC was also enabled for VP8 and H264 along the way.
◆ Where it's heading
This is infrastructure being hardened rather than repositioned. The audit-driven fixes arriving in a batch with named credits, plus the libsrtp bump to a 3.0.0 beta, suggest the project is working through a review of its packet-parsing surface — the part of an SFU that touches untrusted input. The subchannels-over-pipe work is the one feature arc: it makes data-channel subchannels usable in multi-worker routing topologies, which matters for anyone scaling a single conference across workers.
◆ Prediction
Expect the remaining audit findings to keep landing as patch releases on the 0.24 line, and further pipe-transport parity work now that subchannels cross that boundary. Nothing in these entries indicates a change in the library's API direction.
FreeSWITCH
0.0MEETINGS
After twenty-one months of silence, FreeSWITCH 1.11 deleted thirty legacy modules and moved on
◆ Current state
The 1.11 line arrived in May 2026 after the 1.10 series had gone quiet since August 2024. Its opening release migrated to PCRE2, upgraded Windows to OpenSSL 3.x, added Debian 13 support and removed roughly thirty legacy modules. The follow-up three weeks later added a reloadcert API for hot TLS certificate reloads across mod_sofia and mod_verto without dropping calls, plus SIP 603 detection and passthrough control.
◆ Where it's heading
The 1.11 releases read as deferred maintenance being paid down in one move: regex library, TLS stack, supported distributions and dead module surface all changed together after a long gap. The reloadcert work points at the same audience — operators who cannot take an outage to rotate a certificate. This is consolidation for long-running production switches, not feature expansion.
◆ Prediction
Expect further 1.11.x releases continuing the security-and-stability framing, with attention on modules affected by the PCRE2 and OpenSSL 3 migrations as deployments upgrade.
