CO Line Loop Supervision (Talk/Hold Abandon)

Description
CO Line Loop Supervision is a Central Office (Telephone Company) feature. This
feature allows for advanced handling of call connections when the distant end
party disconnects. This function is especially useful when calls that have been
placed on hold go unattended and the distant end party hangs up, or when the
caller is connected to voicemail leaving a message and hangs up. The Emerald ICE
receives the disconnect signal from the telephone company and forces the CO line
on‐hook to release the system resource for other uses.
