MarsSeed [1] filed a deletion request for python2-sipsimple [2]: Legacy version, broken because of already deleted Python2-based dependencies. Safe to delete, nothing in AUR depends on this. Current version of this library uses Python 3 and is available from AUR: https://aur.archlinux.org/packages/python-sipsimple [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-sipsimple/
