3CX vs FreeSWITCH: at a glance
What is 3CX?
3CX is rebuilding around an AI Server, and it just handed the channel the AI edition to sell.
Recent releases split between the AI Server — sizing guidance, deployment updates, MCP and admin control in the V20 Update 10 alpha — and steady client work, most recently the V5.8 softphone beta with one-click SSO and outbound number choice. Packaging moved too: partner and distributor NFR subscriptions were replaced with the AI Edition.
What is FreeSWITCH?
With the legacy purge done, FreeSWITCH spent 1.11.2 bounds-checking everything that parses bytes
FreeSWITCH shipped 1.11.2 in August 2026, three months after the 1.11.0 branch cut that removed roughly thirty modules and migrated the regex engine to PCRE2. Where 1.11.0 was about deleting surface area, 1.11.2 is about auditing what remains: nearly every bug line is a bounds or length check in a parser — STUN attributes, base64 decode, XML entity decoding, RTMP H.264 NAL units, XML-RPC WebSocket frames, MSRP body lengths. Alongside the fixes it adds an interface allowlist and turns on DTLS client-certificate verification against the SDP fingerprint plus opt-in STUN MESSAGE-INTEGRITY checks on inbound ICE. The build system continues moving off self-hosted infrastructure onto GitHub-published artifacts and upstream packages.

6.3MEETINGS
3CX is rebuilding around an AI Server, and it just handed the channel the AI edition to sell.
◆ Current state
Recent releases split between the AI Server — sizing guidance, deployment updates, MCP and admin control in the V20 Update 10 alpha — and steady client work, most recently the V5.8 softphone beta with one-click SSO and outbound number choice. Packaging moved too: partner and distributor NFR subscriptions were replaced with the AI Edition.
◆ Where it's heading
The AI Server is being treated as infrastructure customers deploy themselves rather than a hosted add-on, with hardware guidance, dedicated deployment tooling and an MCP endpoint for connecting assistants. Putting the AI Edition into partner hands and easing self-managed subscription changes both point at pushing that stack out through the channel rather than upselling it centrally.
◆ Prediction
Expect V20 Update 10 to move from alpha toward release with the AI Server management changes already previewed, and the V5.8 softphone beta to reach general availability.
FreeSWITCH
2.5MEETINGS
With the legacy purge done, FreeSWITCH spent 1.11.2 bounds-checking everything that parses bytes
◆ Current state
FreeSWITCH shipped 1.11.2 in August 2026, three months after the 1.11.0 branch cut that removed roughly thirty modules and migrated the regex engine to PCRE2. Where 1.11.0 was about deleting surface area, 1.11.2 is about auditing what remains: nearly every bug line is a bounds or length check in a parser — STUN attributes, base64 decode, XML entity decoding, RTMP H.264 NAL units, XML-RPC WebSocket frames, MSRP body lengths. Alongside the fixes it adds an interface allowlist and turns on DTLS client-certificate verification against the SDP fingerprint plus opt-in STUN MESSAGE-INTEGRITY checks on inbound ICE. The build system continues moving off self-hosted infrastructure onto GitHub-published artifacts and upstream packages.
◆ Where it's heading
The 1.11.x line reads as a deliberate two-step: cut the maintenance surface, then harden what is left. Having removed thirty modules, the project can now afford to audit the media and signaling paths line by line, and the pattern of fixes — untrusted length fields reaching memory writes — suggests a systematic pass rather than incremental reports. The parallel thread is dependency modernization: mod_v8 moved from a custom v8-6.1 fork to upstream libnode, SpanDSP and libvpx were bumped, and Windows builds now pull pre-compiled FFmpeg and libcodec2 rather than building them. Both threads point the same direction — less bespoke code to own.
◆ Prediction
Expect the hardening pass to continue into the remaining parsers, with the opt-in STUN MESSAGE-INTEGRITY check becoming default once operators have shipped through a release. The build-system migration off files.freeswitch.org appears partway done, so the next release likely finishes moving the remaining assets to GitHub-hosted artifacts.
