About 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.
