We have published an update 7 on 25.01 with several important stability fixes.
Please note update 6 had a search indexing fix that again exposed some previously hidden issues e.g. related to building hibernate Phone beans from both DB and UI, and we didn't catch those during regression testing. So we were undoubtedly too quick pulling the GA trigger on update 6.
We have also now bottomed out and resolved why sipxproxy and sipxrelay services failed to interconnect during startup on slightly slower HW platforms, and in that context also refactored some of the new systemctl based service scripts.
Some of these fixes were not trivial and took quite some time for us to troubleshoot -- admittedly our Norway based dev team have also been somewhat preoccupied with the late night escapades of Haaland&co in the US Soccer WC during the last few weeks.
