发明名称 Dual-line telephone bridging device that gives remote telephones access to communications features
摘要 A feature telephone having an internal mechanism for providing access to its features from a remote location. Without third party intervention or the aid of special features on a PBX or public network, a remote user can set up his office phone to transfer telephony features to another phone, such as his home phone. For example, a user can gain access to his company's tie lines and private network from his home telephone. A user can also bill data calls to his office phone or receive office calls at his home phone without the use of a PBX or public network call forwarding feature. According to another aspect of the mechanism, a user can also set up a password to restrict access to his telephone's features and set up a time of day clock to activate call forwarding and feature access between predetermined hours of the day.
