Breakout Dialing

The Breakout Dialing Node

the Breakout Dialing node

The Breakout Dialing node prompts users to enter a number to be connected to.

The collected digits are stored in the internal buffer for the number to be connected to if checks succeed.

Should the user enter a number that is allowed, the call will be connected. If the call completes successfully, the flow ends. Otherwise, the Busy/No Answer exit is taken.

When the user does not enter an allowed number, the node will reprompt the user to enter a number until Max. Iterations is reached (see below).

If Max Iterations is exceeded, the flow will exit down the appropriate branch for the most recent failure condition, i.e. Insufficient Digits or No Match.

Announcements must be selected for the Main announcement, as well as the Reprompt announcement.

The minimum and maximum number of digits that are allowed to be entered must also be specified.

Destination patterns may be added that entered numbers must conform to:

destination patterns

These patterns use the same syntax as the ACS Number Matching node.

If additional configuration options are required, select the arrow icon in the header to display them:

Max. Iterations refers to the total number of attempts the user is permitted before the failure branches are followed.

Both the End Char and the Cancel Char may be disabled if required.

Additionally, the timeout value may be specified in order to override the SRF default timer.

Destination Patterns

Number characters include digits 0 - 9, asterisk, hash, and letters A - F.

Special characters allowed for destination pattern matching are:

Character	Description
[123]	Match one of any character defined in a set, or within any defined range in the set. For example: `[A-F]`
[^123]	Match any character not in the set.
?	Match one of any character.
(123)	Match a group of characters.
123%	Match zero or more of the preceding expression.
<3:5>	Match between 3 and 5 of the preceding expression.
<3>	Match exactly 3 occurances of the precceding expression.
<3:>	Match a minimum of 3 occurances of the precceding expression.

Examples:

Example Pattern	Description	Example Match
021	Match `021` exactly.	`021`
0212%	Match `021` followed by zero or more `2` digits.	`021` `0212` `02122`
(021)%	Match zero or more of the entire group `021`.	`none` `021` `021021`
[AB1-5]%	Match zero or more A and B characters or digits within the range 1 to 5.	`none` `53B212` `B1234A543`
[^AB1-5]%	Match zero or more digits which are not A and B characters or digits within the range 1 to 5.	`none` `F8976` `8879D`
?%	Match zero or more of any digit or character.	`none` `02123B` `022335`
02102<1:2>	Match `0210` followed by one to two `2` digits.	`02102` `021022`
(021)<1:2>	Match on one or two occurrances of the number group.	`021` `021021`
[AB1-5]<1:2>	Match on one or two occurances of the A and B characters or digits within the range 1 to 5.	`3` `3A`
[^AB1-5]<1:2>	Match on one or two digits which are not A and B characters or digits within the range 1 to 5.	`9` `9F`
?<1:2>	Match one or two occurances of any digit or character.	`3` `3A`
?%021	Match any number which ends in 012.	`021` `54321021`

Configuration

To configure the node:

Select the Main announcement that is played to the user when the node is first encountered.
Select the Reprompt announcement that is played to the user after an incorrect code is entered.
Enter the minimum number of digits that the entered number must be.
Enter the maximum number of digits that the entered number may be.
If required, add or remove Destination pattern entries.
If required, set a new value for Max Iterations.
If required, set a new value for Timeout.
If required, set a new value for End Char.
If required, set a new value for Cancel Char.

Note that both announcements and minimum and maximum digits must be selected.
