Fourwaves vs Kamailio: at a glance
What is Fourwaves?
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.
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.
Fourwaves vs Kamailio: editorial side-by-side
Fourwaves
5.0MEETINGS
Fourwaves doubles Free plan submissions to 50 and reworks reviewer assignment.
◆ Current state
Fourwaves ships small dated updates most days. November 11 raised the Free plan from 25 to 50 submissions, and November 12 added a four-step Assign reviewers window. Earlier in November it brought offline mobile check-in for Pro organizers and saved email templates for Advanced and Pro.
◆ Where it's heading
Most releases go to organizer tools for running the event and the review process, with features gated to paid plans. The Free plan increase is the first move in this run that widens the entry tier rather than adding to paid ones.
◆ Prediction
Expect more steps in the submission and review workflow to follow the new reviewer window; whether the Free plan change is part of a wider pricing revision is unclear from the entries.
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.
