    Three-Way Calling (TWC) non-Centrex is a custom calling feature that allows a customer to add a third party to an existing conversation without operator assistance. The party initiating TWC may hold one party with privacy exclusion while dialing and talking with another party (referred to as consultation hold) and can later include the held party in TWC. The added party may be dropped from the connection by a flash from the initiating party. This Generic Requirements document (GR) provides the view of Telcordia on generic requirements for TWC.
