The Cascade Rule ​
This page contains instructions on how to set up the Cascade rule.
Overview ​
When the Cascade rule is in place, VoipNow routes calls to other local or remote extensions as well as user group, if the targeted extension is not available. This rule is only available for Phone terminal extensions.
Rule Structure ​
The Cascade rule structure is:
INFO
<Cascade> when CallerID <callerID_action> <number> and call is in time interval <time_interval> and ring below numbers for <ring_time> seconds:
+/- call number <destination_number> after <waiting_time> seconds
Add in position <rule_position>. Can be managed from the extension with keypad code <key_value>. <Follow/Do not follow> other rules when call is not completed.
Rule Options ​
This table contains parameters you can change for setting up the Cascade rule.
| Option | Description |
|---|---|
<callerID_action> | Choose when the Authenticate rule is performed:
|
<number> | Specify an extension number or a regular expression the incoming call will be matched to. Number matching is based on the CallerID. If the remote party does not send a CallerID, no matching can be performed. However, you can use the Is anonymous option to route anonymous calls. Pay attention to the <number> entry. You can specify the number as a combination of the 0-9 digits and the '+', 'X', 'Z', 'N', '[', ']', '.', '*' characters. The number entry supports the Asterisk number matching. |
<time_interval> | Choose the time interval during which the incoming calls must be checked. Default value: Anytime. |
<ring_time> | Specify for how many seconds the destination cascade extension(s) will be rung when an incoming call is received. |
<destination_number> | Fill in the numbers to be called in cascade. It is possible to add up to 10 cascade rules to a single rule using the +/- icons. The destination numbers may belong to other local extensions, remote extensions or user groups. If you set the transfer to a user group ID, it means that all extensions of users in that group will ring. |
<waiting_time> | Specify after how many seconds since the previous destination was called VoipNow will attempt to call the next one. |
<rule_position> | Specify the rule's order in the list. The rule's position in the group is very important because it defines the order in which VoipNow verifies the call rules in case an incoming call is received. The checking is made in order and all rules are final (meaning that the program stops checking when the first rule is matched). |
<key_value> | Specify a key that can be used to enable the routing rule from the phone terminal pad by dialing 74 <key_value>.The Can be managed from the extension with keypad code <key_value> text is only displayed for Phone Terminal extensions. |
<Follow/Do not follow> | Specify if you want the rule to be considered final or not:
