Callback number lists contain up to 16 numbers. These numbers replace the actual number of the calling party when the call is sent to the Emergency Services Operator (PSAP). If the PSAP operator calls back (to the callback number) the call is routed using a Transformation Table entry back to the original calling extension.

To create or modify Callback Number List:

  1. In the WebUI, click the Settings tab.

  2. In the left navigation pane, go to Emergency Services > Callback Number Pool.
