OpenSIPS vs TrueConf
A side-by-side editorial comparison of OpenSIPS and TrueConf — release velocity, themes, recent moves, and the top alternatives to consider.
OpenSIPS vs TrueConf: at a glance
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 TrueConf?
TrueConf takes its on-prem pitch to GITEX after a month of PHP patches.
A critical PHP vulnerability in TrueConf Server's web service (PHP2Shell, all versions through 5.5.7) drove a security advisory, the 5.5.8 release and matching 5.4.11 and 5.3.11 updates. TrueConf Room gained better calendar-connector handling. Since then the feed is event marketing, with recaps of ADIPEC and plans for GITEX GLOBAL.

OpenSIPS
0.0MEETINGS
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.
TrueConf
5.0MEETINGS
TrueConf takes its on-prem pitch to GITEX after a month of PHP patches.
◆ Current state
A critical PHP vulnerability in TrueConf Server's web service (PHP2Shell, all versions through 5.5.7) drove a security advisory, the 5.5.8 release and matching 5.4.11 and 5.3.11 updates. TrueConf Room gained better calendar-connector handling. Since then the feed is event marketing, with recaps of ADIPEC and plans for GITEX GLOBAL.
◆ Where it's heading
TrueConf sells on-premises communications to regulated and industrial customers, and recent releases are mostly about keeping several supported server versions patched. Feature work, such as quick polls and chatbot buttons in 5.5.6, comes in smaller monthly steps.
◆ Prediction
Expect the November security update and a 5.5.9 server release, with feature work resuming in the 5.5 line.
