asterisk users - Mar 2007 - No application 'Prefix' for extension in1.2x, what app I have to use instead?

Hi
I want to use Prefix app in extensions but get this error:

WARNING[9255] pbx.c: No application 'Prefix' for extension ...

I am just want to do somethig like this:

exten => _9XXXXXXX,1,ANSWER()
exten => _9XXXXXXX,2,Wait(1)
exten => _9XXXXXXX,3,Prefix(511)
exten => _5119XXXXXXX,4,DeadAGI(a2billtest.php|1)
exten => _5119XXXXXXX,5,Hangup()

Please someone tell me how to install Prefix/Suffix application, or
tell if it has been deprecated in 1.2.x versions... what command I
have to use instead?

Prefix was deprecated in 1.0 and removed in 1.2

Use this instead of Prefix():

exten => _9XXXXXXX,1,ANSWER()
exten => _9XXXXXXX,2,Wait(1)
exten => _9XXXXXXX,3,Goto(511${EXTEN},1)

exten => _5119XXXXXXX,1,DeadAGI(a2billtest.php|1)
exten => _5119XXXXXXX,2,Hangup()
