Occasionally, a subscriber may miss an important telephone call because he or she was already talking to someone else when the call
came in. These subscribers need an inexpensive service that would allow them to place one call on hold while they answer the incoming
call. This Generic Requirements document (GR) describes the view of Telcordia on generic requirements for Call Waiting (CW), which
informs a busy station user, by a burst of tone, that another call is waiting. This document also includes a Call Forwarding Don't
Answer (CFDA) interaction. The modification is intended to ensure a uniform feature interaction in a multi vendor environment.
