Information on hold telephony service

摘要

An on hold telephone service that allows a subscriber to the service to place a call on hold and make information services available to the party placed on hold. The on hold service can be implemented on a central office switch or an enhanced services platform connected to the switch. The on hold service is accessed by the subscriber to the service through a transfer function that causes the call to be maintained by the on hold service. The party so placed on hold by the subscriber can then interactively acquire the various types of information made available by the service, such as news, weather and stock market information. The subscriber to the service can then send a message to the other party or cause him to be reconnected to the subscriber either immediately or when the other party is finished using the service and is ready to be reconnected to the subscriber.
