  • Patent number: 5579381
    Abstract: In methods and apparatus for providing suppressed ringing access to a subscriber line, a connection request is sent from a server to a telecommunications switch and the switch performs a connection routine in response to the connection request to connect the server to the subscriber line. The connection routine is adapted to avoid audible ringing of a telephone set connected to the subscriber line. The connection request comprises a signal indicating a subscriber line to which the server is to be connected and a signal indicating that suppressed ringing access to that subscriber line is desired. The methods and apparatus avoid the need for especially provisioned trunks between the server and the terminating switches by including in the connection request a signal indicating that suppressed ringing is desired and by making the telecommunications switch responsive to that signal.
