Prefix( )


Prefix( ) Prepends the specified digits to the current extension and goes to the resulting extension

 Prefix(   digits   ) 

Prefixes the current extension with the digit string specified by digits and continues processing at the next priority for the new extension. So, for example, if priority 1 of extension 1212 is Prefix(555) , 555 will be prepended to 1212 and the next step executed will be priority 2 of extension 5551212. If you switch into an extension that has no priority n +1 (where n is the current priority), Asterisk will treat it as though the user dialed an invalid extension.

Always returns .

  exten => 1212,1,Prefix(555)  exten => 5551212,2,SayDigits(${EXTEN})
