Abstract: A method is disclosed that enables a user of one telecommunications terminal that is engaged in a call to move or “extend” the call to a second telecommunications terminal without notifying any other party on the call of the move. This is particularly useful in many situations. For example, the user might be at work and engaged in a call with a client on the user's wireline desk telephone. If the user needs to leave the office, the user can extend the call to his or her cell phone, while the call is in progress, without notifying the client. This enables the user to leave the office and continue the call on his or her cell phone without having the client ever know that the user is on his or her cell phone and not in the office.

Abstract: An apparatus and methods are disclosed that provide a plurality of telecommunications management features to a telecommunications terminal that is associated with a corresponding terminal through a private branch exchange. In particular, the illustrative embodiment enables a user to manage the simultaneous use of and interaction between associated telecommunications terminals. This capability can be particularly advantageous when on-premises telecommunications terminals are associated with off-premises telecommunications terminals.

Abstract: An apparatus and methods are disclosed that enable a user to access a telecommunications feature of a private branch exchange (e.g., call forwarding, automatic callback, etc.) by calling, from an off-premises telecommunications terminal, a telephone number that routes to the private branch exchange and that corresponds to the feature. When the telephone number is called, the corresponding telecommunications feature is activated or deactivated, as appropriate. For example, calling “555-1111” from might activate automatic callback, and calling “555-2222” might deactivate automatic callback.

Abstract: An apparatus and methods are disclosed that enable a user of an off-premises telecommunications terminal (e.g., an employee's cell phone, etc.) that is affiliated with a private branch exchange to call the private branch exchange, specifying a desired telephone number to call in the Public Switched Telephone Network. The private branch exchange then calls the desired telephone number, transmitting an on-premises telephone number (e.g., the employee's office phone number, etc.) as the calling party number of the call. In the illustrative embodiment, the on-premises telephone number that is transmitted as the calling party number is determined by referring to a table of off-premises and on-premises telephone numbers that are coupled with each other. Similarly, the present invention enables the user of the off-premises terminal to transfer calls and conference in other parties while providing the corresponding on-premises telephone number to the called party.

Abstract: A wireless handset or other communication device includes a user interface implemented with a display and a number of select buttons. The display provides an array of identifiers arranged in rows and columns, with the identifiers corresponding generally to lines or functions of a communication system. The display also provides a status indication for each of the identifiers. A status indicator for a line identifier may indicate whether the corresponding line is in use by the handset user, in use by another system user, or idle, while a status indicator for a function identifier may indicate whether the function is activated or deactivated by the handset user. The assignment of identifiers to lines or functions may be in accordance with a mapping from a wired system, and the status information may be supplied to the handset from a switch of the wired system.
