asterisk users - Jan 2005 - 484 Address Incomplete

Hello

Whenever i tried to call through my dialer, im getting this error message there:
"484 Address Incomplete"
While i am using MySQL database for user authentication etc.

; extensions.conf
switch => Realtime/test@realtime_ext

Enteries in my extensions_table are like this:
 Field-Name:  id     context       exten           priority     app     appdata
           Data:   1        test   _12345XXXX       1            Wait      2
           Data:    2      test    _1234567XX        1            Wait      2

Can you please guide me what should i do here to avoid this problem.

Thanks
