When the system detects a far-end disconnect signal on a line/trunk where a VMI extension is receiving a call, the system sends the disconnect signal to the VMI extension, whether or not that extension is the only party left on the call. If another party is still on the call, the VMS decides whether to continue or disconnect the party. (The far-end disconnect signal occurs only if you program the VMI port for Reliable Disconnect.) Loop-start lines must be programmed for Reliable Disconnect.
