Asterisk vs Kaltura
A side-by-side editorial comparison of Asterisk and Kaltura — release velocity, themes, recent moves, and the top alternatives to consider.
Asterisk vs Kaltura: at a glance
What is Asterisk?
Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.
Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.
What is Kaltura?
Kaltura goes all-in on agentic AI video — Event OS, avatar roleplay, and an open-sourced AI Agent Skills suite.
Kaltura is in the middle of a sharp pivot toward agentic AI for rich-media platforms. In a single month it has open-sourced an AI Agent Skills suite (so any third-party AI agent can build rich-media experiences), introduced Event OS for AI Agents (natural-language event creation and orchestration), unveiled an avatar-powered roleplay solution for enterprise training, and is presenting an Agentic Revenue Engagement Platform at Forrester. The releases are tightly aligned around one thesis.

Asterisk
5.0MEETINGS
Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.
◆ Current state
Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.
◆ Where it's heading
The visible output is backport discipline rather than feature development. Release notes carry counts, tags and advisory IDs but no feature text, so the changelog reads as a stability and security ledger for a mature telephony core. The certified track deliberately lags mainline and picks up a smaller subset of each cycle.
◆ Prediction
The three release candidates should promote to final within the project's usual short RC window, with the certified branch taking the same fixes a cycle later. Nothing in these entries points to feature work in flight.
Kaltura
8.8MEETINGS
Kaltura goes all-in on agentic AI video — Event OS, avatar roleplay, and an open-sourced AI Agent Skills suite.
◆ Current state
Kaltura is in the middle of a sharp pivot toward agentic AI for rich-media platforms. In a single month it has open-sourced an AI Agent Skills suite (so any third-party AI agent can build rich-media experiences), introduced Event OS for AI Agents (natural-language event creation and orchestration), unveiled an avatar-powered roleplay solution for enterprise training, and is presenting an Agentic Revenue Engagement Platform at Forrester. The releases are tightly aligned around one thesis.
◆ Where it's heading
The arc is clearly from a video platform into an agentic-AI orchestration layer that happens to specialize in video. Kaltura is staking out the position that video, events, training, and revenue engagement should all be run through AI agents talking to its platform — and is willing to open-source the agent-skills layer to make Kaltura the default endpoint for rich-media agents.
◆ Prediction
Expect a paid agent runtime or pricing model on top of the open-sourced skills, deeper avatar/roleplay options for enterprise L&D, and Event OS plug-ins for major collaboration platforms (Teams, Slack, Google Workspace). The next big tell will be how serious enterprise adoption of Event OS becomes versus staying a demo-stage capability.
