Dear Sirs,
I have adopted an orphaned AUR package and tried to fine tune it to be used with Your great Kamailio open source project. I can continue to maintain it in the AUR space. If anything needs to be modified in the package please let me know.
Link to the package: https://aur.archlinux.org/packages/kamailio
or web search !aur kamailio
Regards, Nikos
