GosubIf()

Name

GosubIf() — Conditionally branches to a new location, saving the return address.

Synopsis

        GosubIf(condition?labeliftrue:labeliffalse)

Based upon the evaluation of condition, Gosub will branch execution either to labeliftrue or labeliffalse. You may return to this same place in the dialplan by later calling Return.

	Tip
	The word `label` is often used to denote that you may specify a `priority`; an `extension` and a `priority`; or a `context`, an `extension` and a `priority`. We use the word `label` to avoid having to spell out all of the possible options each time.

      ; Specify a default outgoing Caller*ID if one is not set by a specific channel.
      exten => _NXXXXXX,1,GosubIf($["${CALLERID(num)}" = ""]?setcallerid,1)
      exten => _NXXXXXX,n,Dial(Zap/g1/${EXTEN})
      exten => _1NXXNXXXXXX,1,GosubIf($["${CALLERID(num)}" = ""]?setcallerid,1)
      exten => _1NXXNXXXXXX,n,Dial(Zap/g1/${EXTEN})
      exten => setcallerid,1,Set(CALLERID(num)=6152345678)
      exten => setcallerid,n,Return
