Question 1

What happens when Rtpengine reaches end of life?

Accepted Answer

When Rtpengine reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 20 Rtpengine versions are already EOL. The latest supported version is Rtpengine 26.0, maintained until May 1, 2029. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Rtpengine 26.0 still supported?

Accepted Answer

Yes. Rtpengine 26.0 is actively supported until May 1, 2029. It receives security patches and bug fixes. Check the version table above for the full list of supported Rtpengine releases and their exact end-of-life dates.

Question 3

Is it safe to use Rtpengine after end of life?

Accepted Answer

No. Running Rtpengine after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Rtpengine release.

Question 4

How to upgrade from Rtpengine 14.1 to Rtpengine 26.x?

Accepted Answer

To upgrade Rtpengine from 14.1 to 26.0: (1) review the official migration guide for breaking changes, (2) test your application against the new version in a staging environment, (3) update dependencies that have version constraints, (4) run your full test suite, (5) deploy with a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before EOL.

Question 5

When is the next Rtpengine LTS version?

Accepted Answer

Rtpengine 26.0 is the current Long Term Support release, maintained until May 1, 2029. LTS versions are recommended for production deployments that prioritize long-term stability over new features. Plan your upgrades to coincide with LTS releases whenever possible.

Question 6

How long does Rtpengine support each version?

Accepted Answer

On average, Rtpengine supports each release for approximately 13 months (~1.1 years). LTS releases like Rtpengine 26.0 have extended support windows — maintained until May 1, 2029. The exact EOL date for each version is listed in the table above.
