Fourwaves vs Kamailio: at a glance
What is Fourwaves?
Fourwaves is polishing participant messaging after a pricing reset.
Fourwaves ships small daily changes to its event and conference platform. The past two weeks focused on participant communication — direct-message alerts, richer discussion emails, a communication Preferences page — plus account-page and domain-settings cleanup.
What is Kamailio?
Kamailio's tracked feed shows one thing: a quiet, schema-stable 5.8 maintenance release.
Kamailio is a mature open-source SIP server, and the only release on record here is v5.8.7, a maintenance drop on the 5.8 stable branch. It carries fixes since 5.8.6 with no database schema or configuration language changes, and upgrading is strongly recommended for 5.8.x deployments.

Fourwaves
6.3MEETINGS
Fourwaves is polishing participant messaging after a pricing reset.
◆ Current state
Fourwaves ships small daily changes to its event and conference platform. The past two weeks focused on participant communication — direct-message alerts, richer discussion emails, a communication Preferences page — plus account-page and domain-settings cleanup.
◆ Where it's heading
The September 17 pricing change to yearly submission limits with unlimited events set the commercial frame; the product work since then makes ongoing participant engagement smoother. Direct messages are replacing older contact paths.
◆ Prediction
More notification and messaging controls for participants and organizers are likely, continuing the current run of small communication fixes.
Kamailio
0.0MEETINGS
Kamailio's tracked feed shows one thing: a quiet, schema-stable 5.8 maintenance release.
◆ Current state
Kamailio is a mature open-source SIP server, and the only release on record here is v5.8.7, a maintenance drop on the 5.8 stable branch. It carries fixes since 5.8.6 with no database schema or configuration language changes, and upgrading is strongly recommended for 5.8.x deployments.
◆ Where it's heading
With a single maintenance entry, the visible pattern is conservative branch upkeep: fixes land without forcing operators to touch configs or schemas. The feed does not yet show new feature branches or capability shifts.
◆ Prediction
One entry is too little to call a next move; the only grounded expectation is further 5.8.x point releases on the same no-migration terms.
