Types of Nodes

Starting Nodes

These Nodes lay the groundwork for the scenario based on the Scenario Type, being used to simulate an IVR or Agent Probe scenario.

makecall

This node is at the start of every IVR scenario and cannot be added or deleted. It is used to simulate calls being made.

Node Properties:

Property	Description
Name	Name of the Node
Description	(Optional) Description of the Node
Destination Number	Phone Number to be called
Terminate on Timeout	Yes/No
Action	None - No action required. Wait For Sound - Any sound will prevent timeout. Wait for Prompt - runs a Pattern Correlator test to compare against a selected audio file
Action timeout, sec	Time, in seconds, for action to be fulfilled before timeout
Extra delay, sec	Delay, in seconds, after action is fulfilled before moving onto next step

NOTE: Audio Files can be selected for use after uploading them under Scenario Files.

If 'Wait for Prompt' is the selected action, the following two properties will also appear (and will for other applicable nodes below as well):

Property	Description
Audio Sample File Name	The name of the audio file to be used in the comparison test
Audio Quality Threshold	The minimal Quality score of the test, in percentage, for the action to be regarded as fulfilled

answercall

This node is at the start of every Agent Probe scenario and cannot be added or deleted. It is used to simulate calls being answered.

Node Properties:

Property	Description
Name	Name of the Node
Description	(Optional) Description of the Node
Terminate on Timeout	Yes/No
Action	None - No action required; Wait For Sound - Any sound will prevent timeout; Wait for Prompt - runs a Pattern Correlator test to compare against a selected audio file
Action timeout, sec	Time, in seconds, for action to be fulfilled before timeout
Extra delay, sec	Delay, in seconds, after action is fulfilled before moving onto next step
Answer timeout, sec	Time, in seconds, for the call to be transferred to the agent before timeout

agentprobe

By default, this node comes after the Answer Call node in the Agent Probe scenario. It is used to simulate calls being transferred to an agent.

This step involves two parts:

Synchronization - Uses DTMF to sync the caller and the agent. The DTMF sequence should be the same for both of them.
Echo - The calling script sends the audio sample to test for Perceptual Evaluation of Speech Quality (PESQ).

Node Properties:

Property	Description
Name	Name of the Node
Description	(Optional) Description of the Node
Terminate on Timeout	Yes/No
Maximum Number of Synchronization Attempts	Maximum number of attempts to Sync using the correct DTMF Sequence before timeout.
Sync DTMF Sequence	The sequence to be entered by the agent to begin syncing. Leave this blank to enable automatic syncing.
Wait for DTMF response timeout, sec	Time, in seconds, for DTMF to receive correct response before timeout
Echo timeout, sec	Time, in seconds, for PESQ to be received before timeout

These Nodes are used to build the transitioning steps in the scenario.

The DTMF Node simulates a DTMF response by entering a DTMF sequence.

Node Properties:

Property	Description
Name	Name of the Node
Description	(Optional) Description of the Node
Terminate on Timeout	Yes/No
DTMF Sequence	The DTMF Sequence to be entered to transition to this step
Action	None - No action required. Wait For Sound - Any sound will prevent timeout. Wait for Prompt - runs a Pattern Correlator test to compare against a selected audio file
Action timeout, sec	Time, in seconds, for action to be fulfilled before timeout
Extra delay, sec	Delay, in seconds, after action is fulfilled before moving onto next step

voice

The Voice Node plays an audio file. This needs to be uploaded under 'Scenario Files' before it can be used in the test case.

Node Properties:

Property	Description
Name	Name of the Node
Description	(Optional) Description of the Node
Terminate on Timeout	Yes/No
Send Voice	Select an audio file to be played for this step
Action	None - No action required. Wait For Sound - Any sound will prevent timeout. Wait for Prompt - runs a Pattern Correlator test to compare against a selected audio file
Action timeout, sec	Time, in seconds, for action to be fulfilled before timeout
Extra delay, sec	Delay, in seconds, after action is fulfilled before moving onto next step

probe

The Probe Node transfers the call to a simulated agent. A PESQ file must be uploaded under 'Scenario Files' before it can be used in this node.

Node Properties:

Property	Description
Name	Name of the Node
Description	(Optional) Description of the Node
Terminate on Timeout	Yes/No
Sync DTMF Sequence	The sequence to be entered by the agent to begin syncing. Leave this blank to enable automatic syncing.
Wait for DTMF response timeout, sec	Time, in seconds, for DTMF to receive correct response before timeout
PESQ File Name	Name of wav file to be used PESQ analysis
Timeout after Sync, sec	Delay, in seconds, after the probe has sent the Synchronization DTMF sequence signal
PESQ Timeout, sec	Insert Description Here
Timeout after PESQ, sec	Insert Description Here
