Abstract:
PROBLEM TO BE SOLVED: To provide a telephone exchange device that is capable of preferentially connecting an incoming call to the last extension terminal when a caller makes a phone call by dial operation to the same group again after being disconnected once after having a telephone conversation with a user of the extension terminal belonging to the group. SOLUTION: When an incoming call to a multi-appearance group (500) arrives from an external telephone terminal TT1 and a response to the incoming call is executed with the extension terminal DKT4 belonging to the multi-appearance group (500), a telephone number of the external telephone terminal TT1 and an extension number of the extension terminal DKT4 are made to correspond to each other so as to be stored into a respondent management table 152 by a central control part 14 of a main device 1. When receiving the incoming call to the multi-appearance group (500) from the external telephone terminal TT1 again, the extension terminal DKT4 is rung first after specifying the extension number of the extension terminal DKT4 while referring to the respondent management table 152 on the basis of the telephone number of the external telephone terminal TT1.

Abstract:
PROBLEM TO BE SOLVED: To provide a communication connection apparatus enabling a certain user in a group to reliably get a call if it is an incoming call based on identification information representing a plurality of cellular phones. SOLUTION: Upon receiving a signal from a calling source by its own apparatus, the communication connection apparatus establishes connection between the calling source and a predetermined cellular phone. The apparatus receives the signal from the calling source while using identification information used for identifying individual cellular phones as first information and identification information representing the plurality of cellular phones as second information. If the received signal includes the second information, the apparatus reads the first information associated with the second information included in the received signal from a storage device storing the first and second information so that they are correlated with each other. Then, the apparatus calls a cellular phone to be specified based on the read first information according to a predetermined order. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To solve the problem wherein a user must call a plurality of telephone numbers to call the called party in some cases when making contact in audio communication, and it takes time to dial the plurality of numbers. SOLUTION: According to this apparatus, a plurality of addresses of the called party whom a calling party frequently making a call are registered in a packet switching network service provider such as a VoIP network service provider, and an IP/MPLS backbone network 110 can dial the numbers on behalf of the calling party until the called party is reached or until a list of call available telephone numbers has been exhausted. Further, the network 110 can also confirm the calling party whether the network should dial a particular telephone number of the called party in the list of call available telephone numbers, and the network can dial the selected telephone number.

Abstract:
PROBLEM TO BE SOLVED: To provide an IP telephone system capable of switching access methods in the order desired by an opposite party without enforcing an entry operation of other destination number on a user in the case that another access method is selected to re-access the opposite party because the opposite party is busy. SOLUTION: The IP phone 101 acquires NAPTR records of an opposite party from an ECUM server 103 on the basis of a dialed destination telephone number, and selects a NAPTR record used for making a call according to the priority among the acquired NAPTR records. The IP phone 101 makes a call to the opposite party on the basis of an access method and a destination number described in the selected NAPTR record. When the IP phone 102 of the called opposite party is busy, the IP phone 101 selects the NAPTR record of the second order and automatically switches the access method to make a re-access.
