In questa mini serie di articoli vedremo diversi cicli, creati tramite il Dialplan di Asterisk. <\/p>\n\n\n\n

PROBLEMA<\/em>
Talvolta \u00e8 necessario eseguire un’azione pi\u00f9 volte prima di continuare nel dialplan.<\/p>\n\n\n\n

SOLUZIONE<\/em>
Creare dei cicli (loop). Di seguito un esempio.<\/p>\n\n\n\n

ESEMPIO
<\/strong>Come creare dei cicli tramite il Dialplan di Asterisk che itera un numero di volte predefinito utilizzando un contatore con While\/EndWhile.<\/p>\n\n\n\n

[While-Loop]
exten => s,1,NoOp(Operazione ripetuta 5 volte)
same => n,Set(VAR_ITERA=1)
same => n,NoOp(Inizio del loop)
same => n,While($[${VAR_ITERA} <= 5])
same => n,NoOp(Il valore della variabile VAR_ITERA \u00e8: ${VAR_ITERA})
same => n,Set(VAR_ITERA=${INC(VAR_ITERA)})
same => n,EndWhile()
same => n,NoOp(Fine del loop)
same => n,Hangup()<\/p>\n\n\n\n

In questo esempio il ciclo While\/EndWhile eseguir\u00e0 il codice contenuto per 5 volte.
Infatti, il ciclo sar\u00e0 in esecuzione fino a quando la variabile VAR_ITERA, che inizialmente \u00e8 valorizzata a 1 e che ad ogni esecuzione del ciclo si incrementa di valore +1, avr\u00e0 valore <= 5 While($[${VAR_ITERA} <= 5])<\/em><\/p>\n\n\n\n

L’incremento della variabile VAR_ITERA viene fatto con l’utilizzo della funzione INC (vedi wiki).<\/p>\n\n\n\n
