Abstract

The call hold state notification system functions to provide an indication to the parties presently served by the existing call connection that the original hold state has been terminated. This is accomplished by enabling both parties (multiple parties on a n-way call) to a call connection to place their respective call termination on hold to serve another call or to perform some other task without having to physically monitor the call connection. When any party to the call connection removes the hold state at their respective telephone station set, the remaining parties to the call connection who have a hold state active at their termination receive a notification of the reconnection of the party to the call connection. Optionally, the returning party also receives a notification that the call connection is in an on hold state at the other end of the call connection and that party is being advised of the termination of the held state by the returning party.
