发明名称 Extending a call to a telecommunications terminal through an intermediate point
摘要 A method and apparatus are disclosed that enable a call-processing server to extend a received call out to a telecommunications terminal endpoint, wherein the terminal, such as a hotel room phone, is local to and accessible only through an intermediate point, such as a hotel switchboard. Also disclosed are a method and apparatus that enable a data-processing system, such as a server, to determine whether or not to grant a telecommunications terminal endpoint one or more privileges, without some of the disadvantages of the prior art. The methods and apparatus that are taught in this disclosure can be used for extending the incoming call to the endpoint independently of or in the absence of determining whether or not to grant privileges to the endpoint.
