rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
A side-by-side editorial comparison of Nextcloud Talk and OpenSIPS — release velocity, themes, recent moves, and the top alternatives to consider.
Nextcloud Talk v25 adds classified conversations and an owner role, targeting regulated enterprise deployments.
Nextcloud Talk is on a tight release candidate track for v25, with alpha and two RCs shipping in quick succession. The alpha introduced classified conversations, a new owner role with promotion controls, global message search, and a preservation setting that prevents conversation deletion—enterprise and compliance-grade additions. Maintenance releases for v22 and v23 continue in parallel, with backported security and UI fixes.
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
Nextcloud Talk is on a tight release candidate track for v25, with alpha and two RCs shipping in quick succession. The alpha introduced classified conversations, a new owner role with promotion controls, global message search, and a preservation setting that prevents conversation deletion—enterprise and compliance-grade additions. Maintenance releases for v22 and v23 continue in parallel, with backported security and UI fixes.
The classified conversations, preservation settings, and call group restrictions in v25 are directly applicable to regulated sectors—healthcare, government, legal—where communication visibility and retention are controlled. Configurable call summary prompts in RC2 add an AI layer to meeting intelligence. Nextcloud Talk is positioning as the self-hosted alternative for organizations that can't route communications through SaaS platforms.
v25 stable is likely days away given RC3 is minor fix work. Expect the configurable AI call summaries to expand toward action-item extraction and transcript search in subsequent releases, following patterns from commercial meeting intelligence tools.
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
The product is moving toward a 4.0 major release through a standard RC cycle. A second RC a month after the first suggests stabilization work rather than new scope, but the entries do not say what 4.0 changes.
A 4.0.0 general release is the next expected step; what it contains cannot be read from these announcements.
