Name

While() — Starts a while loop

Synopsis

While(expr)

Starts a while loop. Execution will return to this point when EndWhile() is called, until expr is no longer true. If a condition is met causing the loop to exit, Asterisk continues execution of the dialplan on the next priority after the corresponding EndWhile().
