" displays the list of current calls as displayed with the execute command 

. The list is dis-

played in the state it has at the time of display, not in the state it had when the signal was generated.

The URC's occurrence indicates call status changes for any of the calls in the list of current calls.

displayed is always the current configuration at the time of the last display.

The list of active calls displayed with this URC will always be terminated with an empty line preceded by prefix

''^SLCC: '', in order to indicate the end of the list. 

The read command returns an indication whether event reporting is active for the current interface.
