Set Agent State
The Set Agent State allows you to set an agent's state.
The Set Agent State block may take the Authentication Failed conditional exit if the supplied extension number and PIN combination does not match credentials of any configured user.
Agent’s digital ID (extension)
Agent’s digital ID is the agent’s extension number or the name of the variable that holds the extension number (e.g., $(varPhone)).
Over the phone agent PIN
Over the phone agent PIN is the agent’s PIN or the name of the variable that holds the agent’s PIN (e.g., $(varPIN)).
This is the desired new state to set the agent to.
