Description
Cisco ATA 1 informs the Cisco CallManager that Cisco ATA 1 is
not in an OffHook condition, and simultaneously provides calling
party number information to the Cisco CallManager.
When the Cisco ATA detects that one port is in an off-hook state,
the Cisco ATA turns on the lamp, then turns off the lamp once both
ports are in the on-hook state.
