Exchange system and method of connecting calls in said exchange system
First Claim
1. An exchange system, to which a plurality of extension terminals are connected, for connecting a network to any of said plurality of extension terminals upon an incoming-call from the network, incoming call information which includes at least first extension terminal information which designates a first extension terminal and attribute information which indicates a communication attribute, said exchange system comprising:
- memory means for storing second extension terminal information which designates a second extension terminal in correspondence with the communication attribute; and
calling means for calling the second extension terminal designated by the second extension terminal information stored in said memory means if the first extension terminal is busy.

Abstract
Disclosed is an exchange system, to which a plurality of extension terminals are connected, for effecting a connection to any of the extension terminals upon receiving, from a network, incoming-call information which includes at least extension terminal designating information or attribute information. Also disclosed is a call connecting method in this exchange system. The plurality of extension terminal designating information and the extension terminal information are stored, in correlation, in a first memory, and representative extension information corresponding to the attribute information are stored in a second memory. Reference is made to the first memory to decide an extension terminal corresponding to the extension terminal designating information contained in the incoming-call information. When a decided extension is incapable of receiving an incoming call, a connection is made to a substitutable extension. When all of these substitutable extensions are incapable of received an incoming call, or when there is no extension designating information, an extension terminal having an attribute coinciding with the attribute information contained in the incoming-call information is decided and an incoming call is connected to the extension terminal decided.

3. An exchange system, to which a plurality of extension terminals are connected, for connecting a network to any of said plurality of extension terminals upon an incoming call from the network, incoming-call information which includes at least first extension terminal information which designates a first extension terminal and first attribute information which indicates a first communication attribute, said exchange system comprising:
-
memory means for storing forward-destination information which designates a second extension terminal in correspondence with the first extension terminal and second attribute information which indicates a second communication attribute of the second extension terminal; and control means for comparing the second attribute information of the second extension terminal designated by the forward-destination information with the first received attribute information included in the incoming-call information, and for calling the second extension terminal if the second attribute information is coincident with the first attribute information; wherein, if the second attribute information of the second extension terminal designated by the forward-destination information is not coincident with the first attribute information, then said control means calls the first extension terminal designated by the first extension terminal information. - View Dependent Claims (4)

An exchange system, to which a plurality of extension terminals are connected, for connecting a network to any of said plurality of extension terminals upon an incoming-call from the network, incoming-call information which includes first extension terminal information which designates a first extension terminal and first attribute information which indicates a first communication attribute, said exchange system comprising:
-
memory means for storing forward-destination information which designates a second extension terminal in correspondence with said first extension terminal and second attribute information which indicates a second communication attribute of the second extension terminal; and control means for identifying whether or not the second attribute information of the second extension terminal designated by the forward-destination information is coincident with the first attribute information included in the incoming-call information, and if said second attribute information is coincident with said first attribute information, then for calling the second extension terminal designated by the forward-destination information. - View Dependent Claims (6, 7)

8. An exchange system, to which a plurality of extension terminals are connected, for connecting a network to any of said plurality of extension terminals upon an incoming-call from the network, incoming-call information which includes at least first extension terminal information which designates a first extension terminal and first attribute information which indicates a first communication attribute, said exchange system comprising:
-
modem means shared by the plurality of extension terminals; memory means for storing second attribute information in correspondence with a communication attribute of said modem means; and control means for judging whether or not the first attribute information corresponds to the second attribute information stored in said memory means, and if the first attribute information corresponds to the second attribute information, then for connecting the network to the first extension terminal designated by the first terminal information via said modem means. - View Dependent Claims (9)

-
storing second extension terminal information which designates a second extension terminal in a memory in correlation with the communication attributes; identifying whether or not the first extension terminal designated by the first extension terminal information, is busy, and calling the second extension terminal designated by the second extension terminal information stored in the memory, if the first extension terminal is busy. - View Dependent Claims (11)

12. A call connecting method in an exchange system to which a plurality of extension terminals are connected, for connecting a network to any of the plurality of extension terminals upon an incoming call from the network, incoming-call information which includes at least first extension terminal information which designates a first extension terminal and first attribute information which indicates a first communication attribute, comprising the steps of:
storing forward-destination information which designates a second extension terminal in correlation with the first extension terminal and second attribute information of the second extension in a memory;
identifying whether or not the first attribute information included in the incoming-call information and the second attribute information of the second extension terminal designated by the forward-destination information are coincident, and if there is coincidence of the attribute information, then connecting the network to the second extension terminal designated by the forward-destination information read out from the memory.- View Dependent Claims (13)
