When I start asterisk 1.8.10 I see:
    == Parsing '/etc/asterisk/users.conf':   == Found
     -- Registered extension context 'app_dial_gosub_virtual_context'; registrar: app_dial
     -- merging incls/swits/igpats from old(app_dial_gosub_virtual_context) to new(app_dial_gosub_virtual_context) context, registrar = pbx_config
     -- Added extension 's' priority 1 to app_dial_gosub_virtual_context
     -- Registered extension context 'parkedcalls'; registrar: features
