This section details all the settings needed to set up a way to make calls to external numbers.
Outbound routing classes
An outbound routing class is a set of outbound routing rules to be verified in order to establish a routing policy applied to a call from an extension to an external number. The rules are matched in the same order as they are shown in the GUI, from top to bottom.
If the match is valid, the corresponding action will be executed and no further rule will be examined.
You can reorder the rules by clicking and dragging the corresponding icon to the desired place.
The following table lists the configurable parameters for each outbound routing class.

Outbound routing rules
And outbound routing rule has two components.
- A set of conditions on the called number. The verification may be carried out on a specific phone number ("exact selection") or on a prefix ("prefix"), or else the rule may be validated on any called number ("Any").
- An ordered list of outbound lines on which the PBX will attempt to route the call. Should an error occur on an outbound line, the PBX will attempt to route the call on the next. The error conditions correspond to a 5xx or 6xx SIP message or a SIP timeout (32 seconds by default). For example, if the PBX receives a 486 Busy Here SIP message, it will make no further attempt to route the call.

La linea di uscita può coincidere con il dominio ritornato dalla query (chiamata diretta al dominio) oppure è possibile forzare comunque una specifica linea di uscita per l’instradamento on-net (ad esempio nel caso in cui sia necessario utilizzare delle credenziali di autenticazione). | Hostname + Linea di uscita / chiamata diretta al dominio. |
Per una descrizione più dettagliata del funzionamento di questa tipologia di instradamento potete fare riferimento alla pagina dedicata alla descrizione del servizio ENUM.
