Estimating the term…
A stable telephone call barge-in without operator intervention is described wherein a telephone line is provided with two separate directory numbers. One directory number is the usual directory number associated with the line. The second directory number is considered the priority directory number which also translates in circuit switched telephony as the same line ID. Therefore, when a call is in a stable state, a person dialing the regular directory number will receive a busy signal. The person can then disconnect and dial the priority number. When the priority number is received, advantageously, a password is entered into the system to verify that the user of the priority number has permission to barge in. If the password is valid, the existing call is disconnected and the party barging in is connected to the called party. The other call may be placed on hold or alternatively may be disconnected with or without an announcement.
