Telephone system and hunting method of channel in the same
First Claim
1. A telephone system equipped with a plurality of interface units each housing a plurality of communication channels, at least one of control channels making pairs with communication channels and one control channel, the plurality of communication channels to which Internet protocol (IP) networks and IP telephone terminals are connected, comprising:
- a memory which stores a group table in which a plurality of groups divided and configured by using terminal IDs corresponding to the plurality of interface units are associated with interface units belonging to the groups; and
a controller which refers to the group table when connection requests arrive from the IP networks or IP telephone terminals via the control channels and also when the communication channels are selected, preferentially selects idle communication channels in the group to which the control channels with the connection requests arrived thereat based on the reference result, and connects the IP networks or the IP telephone terminals that are request origins via the selected communication channels.

6. A hunting method of channels in a telephone system equipped with a plurality of interface units each housing a plurality of communication channels, at least one of control channels making pairs with communication channels and one control channel, the plurality of communication channels to which IP networks and IP telephone terminals are connected, comprising:
-
storing a group table in which a plurality of groups divided and configured by using terminal IDs corresponded to the plurality of interface units are associated with interface units belonging to the groups; and
referring to the group table when connection requests arrive from the IP telephone terminals via the control channels and also the communication channels are selected, preferentially selecting idle communication channels in the group to which the control channels with the connection requests arrived thereat based on the reference result, and connecting the IP networks or the IP telephone terminals that are request origins via the selected communication channels.
