Callgira 2.8.7 is out, and the packaging is in Kubuntu development version (vivid). it should be backported to the ~kubuntu-ppa/ppa updates repository for Kubuntu utopic/14.10.

You will need to know how to work with .deb packaging.

Ping Riddell on #kubuntu-devel for more info.

For bonus points update the calligra-l10n packaging
