Operator queue cascade parameters

The Operator queue cascade node configures reminders for a client waiting for an operator. In Node Inspector, the form has Lifecycle, Reminder steps, and After last step sections.

Lifecycle

Field	Values	Description
Operation	Start cascade / Stop cascade	Starts timers or clears the active cascade for this client.
Restart existing cascade	Yes / No	If the client enters the same node again, previous timers are cleared before a new start.
Stop when operator joins	Yes / No	Clears timers automatically when an operator joins the chat.
Stop when chat is closed	Yes / No	Clears timers automatically when the chat is closed in OperatorLine.
Action after operator joins	No transition, Alias, Event branch, Message	Optional action after timers are cleared because an operator joined.

Action after operator joins

Type	Extra fields	What happens
No transition	—	The cascade only stops.
Alias	Alias	The scenario starts the selected alias.
Event branch	Branch ID	The node gets an output with this ID; connect it to the next node.
Message	Message	The client receives a text message after the operator joins.

Reminder steps

Field	Description
Add step	Adds a reminder step. Limit: 100 steps.
Delay after previous step	Time before this step runs. Counted from the previous step.
Unit	Seconds, Minutes, or Hours.
Send message	Enables a text message for this step.
Message	Text sent to the client.
Transition	No transition, Event branch, or Alias.
Branch ID	Output name for an event branch. It must be unique in the node.
Alias	Alias started after the step.

How delays are counted

Delays are not absolute from cascade start. They add up:

Step	Field value	Approximate time from start
1	3 minutes	3 minutes
2	3 minutes	6 minutes
3	3 minutes	9 minutes

After last step

Mode	Description
Stop cascade	Reminders end after the last step.
Repeat last step	The last step repeats after Repeat delay.
Repeat from first step	The cascade repeats from step 1.

If repeat is enabled, keep at least one automatic stop enabled or add a branch that leads to a stop node. Otherwise, the cascade can run without an end condition.

Canvas outputs

The node creates outputs from Branch ID values set in:

steps with Event branch transition;
Action after operator joins, when Event branch is selected.

Use a new unique ID when adding a branch. Avoid changing a branch ID after it is already connected to another node; if you change it, verify the canvas connection.

Form warnings

Warning	Reason
No steps	Start cascade is selected without any reminder steps.
Only the first 100 steps will be used	Step count is above the limit.
Empty message	Send message is enabled, but text is empty.
Empty alias or branch ID	Selected transition has no target.
Duplicate branch IDs	Two branches use the same name.
Possible infinite loop	Repeat after last step is enabled and no stop condition exists.
