You can test what the command

dbus-send --system --type=method_call --print-reply=True \
 --dest=com.nokia.csd.SS /com/nokia/csd/ss \
 com.nokia.csd.SS.CheckDivert string:21 string:89

returns. If it does not return error

com.nokia.csd.SS.Error.TeleServiceNotProvisioned: Tele service not
provisioned

you can try to redirect calls to your line 1 number with command

dbus-send --system --type=method_call --print-reply=True \
 --dest=com.nokia.csd.SS /com/nokia/csd/ss \
 com.nokia.csd.SS.RegisterDivert string:21 string:89 \
   string:<line1-number-here> uint32:0
