MarsSeed [1] filed a deletion request for nausoftphone7 [2]: Defunct, abandoned, unused binary from 2017.
Upstream seems to no longer provide this VOIP telephony app separately. Instead, it seems to have been integrated into its "Naumen Contact Center" product. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/nausoftphone7/
