IP telephone system and telephone exchange
First Claim
1. An IP telephone system that enables a first telephone terminal and a second telephone terminal to communicate with each other using an internet protocol, the IP telephone system comprising:
- a detection unit that, when the first and second telephone terminals communicate with each other through a first communication route, detects a communication fault in a communication between the first and second telephone terminals; and
a controller that switches a communication route from the first communication route to a second communication route different from the first communication route.

9. A telephone exchange to which a plurality of telephone terminals are connectable and that includes a plurality of interface units through which the telephone terminals are capable of communicating with an IP network by registering a first management table stored in a registration server connected to the IP network, the first management table associating connection IDs identifying the interface units and line IDs identifying a plurality of lines on the IP network, the telephone exchange comprising:
-
a detection unit that detects a communication fault in a communication through each of the interface units including first and second interface units; and a controller that, when the detection unit detects a communication fault in a communication through the first interface unit, generates a second management table that associates a line ID associated with a connection ID for the first interface unit in the first management table, with a second connection ID for the second interface unit and updates the first management table to the second management table.

10. A telephone exchange to which a plurality of telephone terminals are connectable and that includes a plurality of interface units through which the telephone terminals are capable of communicating with an IP network by registering a first management table stored in a registration server connected to the IP network, the first management table associating connection IDs identifying the interface units and line IDs identifying a plurality of lines on the IP network, the telephone exchange comprising:
-
a detection unit that detects a communication fault in a communication through each of the interface units including first and second interface units; and a controller that, when the detection unit detects a communication fault in a communication through the first interface unit, assigns a connection ID for the first interface unit to a connection ID for the second interface unit, and controls the second interface unit to notify the assigned connection ID to the IP network. - View Dependent Claims (11)

12. An IP telephone system wherein a plurality of telephone terminals are connected to a plurality of telephone exchanges that are connectable to an IP network, the telephone exchanges including first and second telephone exchanges connected with each other by a private line and the telephone terminals are capable of communicating with an IP network through a plurality of interface units using a first management table stored in a registration server connected to the IP network, the first management table associating connection IDs identifying the interface units and line IDs identifying a plurality of lines on the IP network, the IP telephone system comprising:
-
a detection unit that detects a communication fault in a communication through each of the interface units including first and second interface units provided in the first and second telephone exchanges, respectively; and a controller that when the detection units detects a communication fault in a communication through the first interface unit in the first telephone exchange, generates a second management table that assigns a line ID associated with a connection ID for the first interface unit in the first management table, to a second connection ID for the second interface unit in the second telephone exchange, and updates the first management table to the second management table.
