What is OpenSIPS?

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.

What is Nextcloud Talk?

Nextcloud Talk v23.0.14 fixes Firefox video and keeps v25 waiting at RC3.

Nextcloud Talk keeps patching its supported branches. On November 5 four branches shipped together with share-permission fixes and password protection for instant meetings; on November 12 v23.0.14 added an option for external call services to set the participant list and fixed a Firefox simulcast race and read-marker checks. The v25 line has not moved past RC3 since September 10.

OpenSIPS vs Nextcloud Talk: editorial side-by-side

0.0

OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

A 4.0.0 general release is the next expected step; what it contains cannot be read from these announcements.

N5.0

Nextcloud Talk v23.0.14 fixes Firefox video and keeps v25 waiting at RC3.

◆ Current state

Nextcloud Talk keeps patching its supported branches. On November 5 four branches shipped together with share-permission fixes and password protection for instant meetings; on November 12 v23.0.14 added an option for external call services to set the participant list and fixed a Firefox simulcast race and read-marker checks. The v25 line has not moved past RC3 since September 10.

◆ Where it's heading

Effort is going into security fixes across every supported branch rather than into shipping v25. The two-month gap since RC3 is the main open question in this feed.

◆ Prediction

Expect further backported fixes across v20 to v23; whether v25.0.0 ships soon is unclear from the entries.
