Built-in variables provide information about things the system tracks automatically, such as the caller’s phone number, or the contact list associated with an outbound flow. This article lists the default system variables built into Architect for each type of flow. You can also access descriptions in the embedded Function and Operator help.

Architect contains various system-scoped variables that begin with Min or Max. These variables hold the minimum and maximum value allowed for certain data types and are similar to constants in many programming languages. In Architect, they are built-in and read-only system variables. For example, the System.MinDateTime variable holds the minimum allowed value of a DateTime data type, which is January 1st, 1800 at 12:00:00 a.m.

Name Type Collection? Read Only? Description
Call.Ani String No Yes The caller’s origination phone number for the active call (Automatic Number Identification).
Call.CalledAddress String No Yes The called address that caused the caller to enter this flow. For a new inbound call, this value is the same as Call.CalledAddressOriginal, but changes for a flow entered by a transfer, for example.*
Call.CalledAddressOriginal String No Yes The called address received when the call first entered the system; typically the phone number dialed by the caller to reach the system. For a specified call, this value never changes.*
Call.ConversationID String No Yes

A unique identifier for the external organization.

Note: To avoid activating error handling, before you use this variable confirm that it has a value.
Call.ExternalTag String No Yes

The external tag for the active call.
Call.Language String No Yes

The IETF language tag lowercase string value set on the current interaction. 

Note: Within call flows, construct comparisons with IETF language tag string values in a case-insensitive manner.
Call.RemoteName String No Yes Remote name for the active call.

System.Currencies Enum No Yes
A list of available currencies in Architect and information about the currencies made available as subproperties, such as ISO 4217 currency code.
System.Languages Enum No Yes

A list of IETF language tags in Architect.

Note: Like Interaction.Language, when accessing the tag property in flows to obtain the IETF language tag string value, construct comparisons to that value in a case-insensitive manner.

*Note: Various actions cause a call to enter a flow, including, but not limited to:
  • An inbound call arrives.
  • A call transfers to a flow by another flow.
  • A call transfers to a flow by a user. 

Each flow makes available to the flow author two "called address" variables. Consumers typically see these addresses as phone numbers, but they can contain other identifies like a SIP address used for voice conversations over the Internet.
