PROBLEMA<\/em>
Si desidera implementare dei limiti di chiamata personalizzati nel dialplan Asterisk.<\/p>\n\n\n\n


SOLUZIONE<\/em>
Utilizzare le funzioni del dialplan GROUP() e GROUP_COUNT():<\/p>\n\n\n\n

exten => _0Z.,1,Set(GROUP(outbound)=myprovider)
same => n,Set(COUNT=${GROUP_COUNT(myprovider@outbound)})
same => n,NoOp(Ci sono in corso ${COUNT} chiamate con myprovider)
same => n,GotoIf($[${COUNT} > 2]?denied:continue)
same => n(denied),NoOp(Superato il limite massimo di chiamate. Chiudo\u2026)
same => n,HangUp()
same => n(continue),NoOp(Canali disponibili. Faccio chiamata)
same => n,Dial(SIP\/my_provider_trunk\/${EXTEN},10)
same => n,Hangup()<\/p>\n\n\n\n

In questo esempio vediamo come utilizzare le funzioni GROUP() e GROUP_COUNT() per limitare il numero di chiamate in uscita per un determinato trunk\/provider (nell’esempio massimo 2 chiamate).
Con la funzione GROUP() definiamo una categoria (nell’esempio “outbound”) e assegniamo un valore\/nome (nell’esempio “myprovider”).
Con la funzione GROUP_COUNT() otteniamo il valore dei canali attivi per qual determinato gruppo.
L’argomento fornito alla funzione GROUP() \u00e8 una categoria ed \u00e8 facoltativo.<\/p>\n\n\n\n
