Carrier independent network services |
摘要 |
The present invention provides a method of establishing Carrier Independent Network Services (CINS) wherein feature and voice information are decoupled such that feature information is transmitted on a signalling link established on private and/or public facilities, but voice information is transmitted over a public network when calls overflow, thereby permitting the terminating node to identify the incoming call and associate feature information provided by the originating node.
