<br style="clear:both;" />
When a Call Request or Ringing Group call is sent to a group of operators, it is sometimes required to activate Call Request Transfer to signal that the Operator Position is no longer manned.  <br>This can be a manual control by the operator, or it could be an automatic control from a PSIM application, resulting in the Operator position no longer receiving the Call Request or Ringing Group Call.  <br>However, all remaining operators should still receive the calls and the escalation should not take place until the last operator has activated the Call Request Transfer.  <br>This application provides an example of how to achieve this. <br>
==Operation==
*A Dummy Subscriber is added as a permanent member of the group, and all automatic escalations are performed at this dummy station
*Operators will press DAK 1, or the PSIM will command DAK 1 to place their location into Transfer.  In doing this, they will remove their directory number from the group.
*When the last operator has placed their location into Transfer, the Dummy Subscriber will activate Call Request transfer.
*If any one operator presses DAK 2, or the PSIM commands DAK 2 to turn off Transfer, the Dummy will deactivate the Call Request Transfer

==Pre-requisites==
*1 Dummy Subscriber to be a permanent member of the Call Request group
*All normal escalation programmed against the Dummy Subscriber
*1 UDD for each Operator, related to their Physical number
*UDD 553 to count the number of operators who are in/out of remote mode.
*Modify the Group nummber, number of operators and call request transfer location as required in the below events
