发明名称 Leaving a message on a held connection
摘要 This invention relates to arrangements for leaving messages from a held telephone. A recording device or system attached to the held telephone station, to a PBX or to a central office switch records the message in response to a request from the held party. Advantageously, this permits a party who has been put on hold by another party a third alternative between the presently allowed alternatives of hanging on or hanging up; a message may be all that is needed and the held party can be saved from frustration.
