Callflows

About Callflows

Callflows are the instructions Kazoo uses to process a call. A callflow includes a list of numbers or regex patterns used by Kazoo to determine what callflow is used when a call comes in for an account. The flow parameter defines the tree of actions, allowing branching (such as in the menu action) and chaining actions together. You can also branch to other callflows and execute its flow (useful to avoid recreating the same sub-flow structure).

Schema

Call flows describe steps to take in order to process a phone call. They are trees of information related to a phone call such as “answer, play file, record file” etc. that are logically grouped together and ordered.

Key	Description	Type	Default	Required	Support Level
`featurecode.name`		`string(1..128)`		`false`
`featurecode.number`		`string(1..30)`		`false`
`featurecode`	When the callflow is used as a featurecode this object tracks the intended match of the pattern and name of the feature	`object()`		`false`
`flags.[]`		`string()`		`false`	`supported`
`flags`	Flags set by external applications	`array(string())`		`false`	`supported`
`flow`	A callflow node defines a module to execute, data to provide to that module, and zero or more children to branch to	#/definitions/callflows.action		`false`
`metaflow`	Actions applied to a call outside of the normal callflow, initiated by the caller(s)	#/definitions/metaflows		`false`
`name`	Friendly name of the callflow	`string()`		`false`
`numbers.[]`		`string(1..36)`		`false`
`numbers`	A list of static numbers that the callflow should execute for	`array(string(1..36))`	`[]`	`false`
`patterns.[]`		`string(1..)`		`false`
`patterns`	A list of regular expressions that the callflow should execute for, with optional capture groups	`array(string(1..))`	`[]`	`false`
`ringback.early`	Media ID for the early ringback media	`string()`		`false`
`ringback.transfer`	Media ID for transfer ringback media	`string()`		`false`
`ringback`	Ringback settings for early media and transfers	`object()`		`false`

callflows.action

Key	Description	Type	Default	Required
`children./.+/`	Call flows describe steps to take in order to process a phone call. They are trees of information related to a phone call such as “answer, play file, record file” etc. that are logically grouped together and ordered.	#/definitions/callflows.action		`false`
`children`	Children callflows	`object()`		`false`
`data`	The data/arguments of the callflow module	`object()`	`{}`	`true`
`module`	The name of the callflow module to execute at this node	`string(1..64)`		`true`

metaflow

A metaflow node defines a module to execute, data to provide to that module, and one or more children to branch to

Key	Description	Type	Default	Required
`children./.+/`	A metaflow node defines a module to execute, data to provide to that module, and one or more children to branch to	#/definitions/metaflow		`false`
`children`	Children metaflows	`object()`		`false`
`data`	The data/arguments of the metaflow module	`object()`	`{}`	`false`
`module`	The name of the metaflow module to execute at this node	`string(1..64)`		`true`

metaflows

Actions applied to a call outside of the normal callflow, initiated by the caller(s)

Key	Description	Type	Default	Required	Support Level
`binding_digit`	What DTMF will trigger the collection and analysis of the subsequent DTMF sequence	`string(‘1'	'2'	'3'	'4'
`digit_timeout`	How long to wait between DTMF presses before processing the collected sequence (milliseconds)	`integer()`		`false`
`listen_on`	Which leg(s) of the call to listen for DTMF	`string(‘both'	'self'	'peer’)`
`numbers./^[0-9]+$/`	A metaflow node defines a module to execute, data to provide to that module, and one or more children to branch to	#/definitions/metaflow		`false`
`numbers`	A list of static numbers with their flows	`object()`		`false`
`patterns./.+/`	A metaflow node defines a module to execute, data to provide to that module, and one or more children to branch to	#/definitions/metaflow		`false`
`patterns`	A list of patterns with their flows	`object()`		`false`
