A telephone caller identification system where potential callers can be assigned to call-in groups, each call-in group having a particular ring. When a member of a particular call-in group calls, the telephone presents the ring associated with that call-in group. A caller not assigned to any call-in group causes the telephone to present a default ring. The telephone can also present particular transfer rings when transferred indicating that the call being transferred is from a caller belonging to a particular call-in group, or provide unique voice mail rings when a member of a call-in group leaves voice mail.
