Kamailio vs vMix: at a glance
What is Kamailio?
Kamailio's feed shows quiet, migration-free upkeep across two stable branches.
Kamailio is a mature open-source SIP server, and its tracked releases are maintenance drops: v6.1.5 on the current 6.1 stable branch and, earlier, v5.8.7 on 5.8. Both carry fixes only, with no database schema or configuration language changes, and the project strongly recommends upgrading within each branch.
What is vMix?
vMix holds its perpetual-license cadence with two major releases in 2025.
vMix shipped versions 28 and 29 during 2025, with the typical eligibility pattern — free for buyers since January 2023 and included for vMix Max subscribers. The blog otherwise covers hardware ecosystem changes (NVENC encoder counts, Core Ultra laptops) and the occasional culture post.

Kamailio
2.5MEETINGS
Kamailio's feed shows quiet, migration-free upkeep across two stable branches.
◆ Current state
Kamailio is a mature open-source SIP server, and its tracked releases are maintenance drops: v6.1.5 on the current 6.1 stable branch and, earlier, v5.8.7 on 5.8. Both carry fixes only, with no database schema or configuration language changes, and the project strongly recommends upgrading within each branch.
◆ Where it's heading
The visible pattern is conservative branch upkeep: fixes land on more than one branch at once without forcing operators to touch configs or schemas. The feed does not show feature releases or capability shifts.
◆ Prediction
Expect further 6.1.x point releases on the same no-migration terms; the entries do not show when the next feature branch is due.
vMix
0.0MEETINGS
vMix holds its perpetual-license cadence with two major releases in 2025.
◆ Current state
vMix shipped versions 28 and 29 during 2025, with the typical eligibility pattern — free for buyers since January 2023 and included for vMix Max subscribers. The blog otherwise covers hardware ecosystem changes (NVENC encoder counts, Core Ultra laptops) and the occasional culture post.
◆ Where it's heading
The two-release year is faster than the historical annual cadence and reads as a deliberate defense of the perpetual-license model: enough major-version value to justify renewals without forcing subscription pricing. Hardware coverage stays GPU- and laptop-focused, reflecting the buyer base of live production operators choosing workstations.
◆ Prediction
Expect the next major release on a similar 9–10 month rhythm and continued hardware-recommendation posts as Intel and AMD ship new generations. The harder watch is whether vMix Max takes on more of the headline features versus the perpetual-licensed core product.
