I think the mirror that had all the packages went down some time ago. It's all somewhat outdated by now and I'm not sure if voice calling works with upstream kernel yet.

Anyway, I can probably put everything up somewhere. If nothing is changed, you need ofono and some sysfs magic to power the modem. For voice calls you can use the ancient pulseaudio with nokia blobs, or try version that are used in mer/nemo/whatever with their modules. It's a mess (or at least was) and I never got it to work that stable with newer pa.
