yochananmarqos [1] filed a request to merge sofia-sip-fs [2] into sofia-sip [3]: There was no reason to create a new package. The original project is unmaintained: "This repository is not currently maintained. The FreeSWITCH project hosts a currently maintained version of this library at https://github.com/freeswitch/sofia-sip" -- https://sofia-sip.sourceforge.net/ [1] https://aur.archlinux.org/account/yochananmarqos/ [2] https://aur.archlinux.org/pkgbase/sofia-sip-fs/ [3] https://aur.archlinux.org/pkgbase/sofia-sip/
