3CX vs PJSIP

3CX vs PJSIP: 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 PJSIP?
A mature SIP stack turns its attention to concurrency correctness and AI voice endpoints
PJSIP remains the reference open-source SIP and media stack for embedded and mobile softphones, shipping roughly one feature release a year. Version 2.17 pairs asynchronous client authentication with a documented real-time AI speech connectivity path, alongside ten separate deadlock fixes. The cadence is slow, but each drop carries a backward-incompatibility section integrators have to read before upgrading.

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.

A mature SIP stack turns its attention to concurrency correctness and AI voice endpoints
◆ Current state
PJSIP remains the reference open-source SIP and media stack for embedded and mobile softphones, shipping roughly one feature release a year. Version 2.17 pairs asynchronous client authentication with a documented real-time AI speech connectivity path, alongside ten separate deadlock fixes. The cadence is slow, but each drop carries a backward-incompatibility section integrators have to read before upgrading.
◆ Where it's heading
The arc from 2.14 to 2.17 moves away from platform and codec breadth — IPv6 dual stack, a Metal renderer, Lyra, a Schannel TLS backend — and toward the harder problem of concurrency inside the media core: async conference bridge operations, then parallel bridging, then async authentication and systematic deadlock elimination. AI speech connectivity in 2.17 is the first indication the project treats voice agents, not only human callers, as a target workload. The growing list of API breaks suggests the maintainers will trade source compatibility for cleaner threading semantics.
◆ Prediction
Expect the next release to widen the AI speech path with more transport and codec options while continuing to convert blocking media-core calls to asynchronous ones.
