Will the Upgrade to Debian 13 soon be released? Debian 12 is EOL since July. Or is 3CX using Debian LTS?
Debian 12 hasn’t reached its end of life (EOL) yet.
It’s important not to confuse EOL with the end of regular support.
Debian 12’s lifecycle is divided into two main support phases:
Standard support: Debian 12 “Bookworm” was released on June 10, 2023 and received regular support from Debian’s Security and Release teams until July 11, 2026.
Long-Term Support (LTS): On July 12, 2026, security maintenance was handed over to the Debian LTS team. This transition is part of Debian’s normal lifecycle. There’s no separate “Debian 12 LTS” release and no operating system upgrade is required. Bookworm will continue receiving LTS security updates until June 30, 2028.
3CX uses the amd64 architecture, which is covered during the Debian 12 LTS phase.
The LTS phase has a more limited scope than standard support in terms of supported architectures and packages.
It’s also worth pointing out that 3CX uses its own repositories rather than Debian’s repositories directly.
So there’s no reason to consider Debian 12 unsupported from a security perspective at this point.
Upgrading to Debian 13 isn’t urgent at all.
Personally, I don’t see much benefit in moving to Debian 13 at this point. If you follow 3CX’s requirements, nothing other than the 3CX PBX should be installed on the same server anyway. So whether 3CX chooses to remain on Debian 12 or, hypothetically, decides one day to move to a closed, custom Linux image designed specifically for this purpose doesn’t really matter to me.
(Just to be clear, I’m only using this as a hypothetical comparison. It’s not a claim, and it’s not based on any rumor)
As long as the underlying operating system remains secure, stable, and free of issues that could affect the PBX, I don’t see what practical difference it makes.
3CX will move to Debian 13 when there’s genuinely more to gain from upgrading than from staying on Debian 12.
