; alternatives which you can enforce by placing a unit drop-in into
; /etc/systemd/system/freeswitch.service.d/*.conf:
;
; User=freeswitch
; Group=freeswitch
; ExecStart=
; ExecStart=/usr/bin/freeswitch -ncwait -nonat -rp
;
; empty ExecStart is required to flush the list.
;
; if your filesystem supports extended attributes, execute
;   setcap 'cap_net_bind_service,cap_sys_nice=+ep' /usr/bin/freeswitch
; this will also allow socket binding on low ports
;
; otherwise, remove the -rp option from ExecStart and
; add these lines to give real-time priority to the process:
;
; PermissionsStartOnly=true
; ExecStartPost=/bin/chrt -f -p 1 $MAINPID
;
; execute "systemctl daemon-reload" after editing the unit files.
