AssistRequestInstructions

Overview

The AssistRequestInstructions operation represents the sending of an INAP AssistRequestInstructions.

This message is sent by the IN Tester when it is simulating the role of an external Specialised Resource Platform (SRP).

Direction: OUTBOUND
From: SRP (IN Tester)
To: SCP (Application Under Test)

Attributes

The operation attributes are as follows.

Attribute	Type	Description
`type`	String	`inap.srp_to_scp.AssistRequestInstructions`
`label`	String	An optional label for this node if it is to be the target of a `branch` operation.
`tcap_ac`	`null` / TCAP alias / Hex String	Specifies the TCAP Application Context to be sent for this outbound TCAP_BEGIN. May be null, a well-known TCAP alias, or a free-form hex string, e.g `04000101010003`. (Default = `null`).
`send_with_next`	Boolean	Request that this INAP operation should be bundled with the next outbound TCAP. (Default = `false`).
`send_and_close`	Boolean	Request that this INAP operation should be sent as TCAP_END. (Default = `false`).
`arguments`	Object	[Required] The structure of the INAP AssistRequestInstructionsArg to construct and send. Expressions may be supplied within this structure.

Example

This is an example entry within the operations array:

{
    "type": "inap.srp_to_scp.AssistRequestInstructions",
    "arguments": {
        "correlationID_digits": "{substr ($i->{EstablishTemporaryConnection}{assistingSSPIPRoutingAddress_digits}, -4)}"
    }
}

Note: The AssistRequestInstructions includes a correlation ID parameter which must match the identifier provided by the SCP in a preceding inbound EstablishTemporaryConnection operation. This example shows how this is typically done, using an expression.

In this case, the outbound ID in the ARI is the last four digits of the most recently received inbound EstablishTemporaryConnection assistingSSPIPRoutingAddress.

Arguments

The following outbound arguments are supported:
