			| Call Flow Variable - Powerful Tool for Advanced Call Flows 
 Anveo is a very powerful, flexible and yet easy to use communication platform for Voice and Data integration.
 One of the major elements of advanced Call Flow is Call Flow Variable.

			| 
					
						| Call Flow Variable can be used to store and retrieve data during Call Flow execution. Here are just a few examples: Integrate Anveo Call Flow with your in-house system via HTTP, verify data entered by a caller, create conditional loops and so on. |  | 
		
			| 
					
						| Anveo has a built-in Call Flow Variable (E164 ( $[E164]$ )) that holds Caller's phone number.
 
 Call Flow variable is represented by its NAME and its VALUE. Example: Variable Name: CustomerID and its value 1203. Call Flow Variable value can be used in most of Anveo Call Controls. To reference a variable simply use $[VARIABLENAME]$ in an appropriate place and ANVEO will replace it with its value.
