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 3CX?

3CX sets the end of 2026 to switch off its own transcription service.

3CX is closing its bundled AI services and moving customers to AI they run or connect themselves. On November 13 it confirmed its transcription service switches off at the end of 2026, with ENT+ subscriptions moving to AI Edition. V20 Update 10 fills in the replacement: Grok support, MCP, improved AI agents and local transcription on a Mac, plus simpler audio conferencing, a pop-out dialer and delegated call recording review.

Kamailio vs 3CX: editorial side-by-side

K
Kamailio
MEETINGS
2.5

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.

6.3

3CX sets the end of 2026 to switch off its own transcription service.

◆ Current state

3CX is closing its bundled AI services and moving customers to AI they run or connect themselves. On November 13 it confirmed its transcription service switches off at the end of 2026, with ENT+ subscriptions moving to AI Edition. V20 Update 10 fills in the replacement: Grok support, MCP, improved AI agents and local transcription on a Mac, plus simpler audio conferencing, a pop-out dialer and delegated call recording review.

◆ Where it's heading

Update 10 widens the choice of AI provider and moves more processing onto hardware customers own, while adding manager controls around recordings. The release is shipping in pieces through how-to posts rather than one changelog.

◆ Prediction

Expect Update 10 to reach general release and more posts on the self-hosted AI Server ahead of the January 2027 licence conversion.
