Description

  The present invention relates to a switching device that can economically and efficiently use IP telephones that have been rapidly spreading in recent years.

With the spread of the Internet, IP telephones are rapidly increasing. However, since IP telephones are blocked for each IP telephone provider, IP telephones between different providers, such as being unable to connect to an IP telephone subscribed to another provider or connecting via a general public line, It tends to be expensive.
In such a case, the advantage that the IP phones are generally free of charge cannot be obtained, and the cost saving is not effective.

  As described above, when an attempt is made to make a call using an IP phone, calls using the IP phone in the same provider are free of charge, and the cost saving effect is enormous.

The telephone number assigned to the IP telephone is determined for each IP telephone provider, and the IP telephone provider can be determined by the telephone number.
For example, an IP telephone is a telephone number starting with 050 or the like, but a number below 050 is assigned by each IP telephone provider, and it is possible to determine which IP telephone provider is an IP telephone by the telephone number.

  Therefore, if the destination telephone number is determined and the call is made by switching to the same provider's line of the provider with whom the destination is contracted, the call is made within the same provider and the effect of saving the call charge can be enhanced. Depending on the time zone, day of the week, and date, depending on the telecommunications company such as the provider, the same effect can be obtained if the line with the lowest call charge is selected according to the time zone, day of the week, date, etc.

  To achieve the foregoing object, the present invention provides a dial recognition unit for recognizing a telephone number from a communication terminal in a switching adapter in which a general line and a provider line are combined or a switching adapter in which at least two provider lines are connected; A dial storage unit for storing the recognized dial, a switching unit for selecting a provider line based on a telephone number and connecting a communication terminal, a dial transmission unit for transmitting a telephone number to the provider line, and a control for controlling the respective units A first step of storing the dial based on information from the dial recognition unit, a second step of analyzing the stored number and dialing the desired provider line, and a provider line Provide the third step of connecting the communication terminal, and realize communication between the communication terminal and the partner communication terminal A dial for recognizing a telephone number from a communication terminal in a switching adapter in which at least two lines of a combination of a general line and a provider line or at least two lines of a provider line are connected. A recognition unit, a dial storage unit for storing the recognized dial, a switching unit for selecting a provider line based on a use time zone and connecting a communication terminal, a dial transmission unit for transmitting a telephone number to the provider line, and The control unit is configured to control each unit, and the control unit stores a dial based on information from the dial recognition unit, a second step of dialing a desired provider line, a provider line, and a communication terminal Providing a third step of connecting the communication terminal and realizing communication between the communication terminal and the partner communication terminal. The IP telephone switching adapter, wherein the invention as claimed in the item 2 is intended to solve the above problems.

  In the present invention, the telephone number of the destination is determined and switched from a plurality of IP telephone providers, and the IP telephone communication between the same providers is selected or a line with a low communication charge is selected. Therefore, communication expenses can be effectively reduced. it can. Similarly, the same effect can be obtained by selecting and transmitting the cheapest line according to the time of day, day of the week, date, and the like. In particular, since the caller can automatically select and communicate without being aware of it, the reduction effect is enormous.

  Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. The IP telephone line connection terminal 11 is connected to a line in which a general line and a provider line are combined or a provider line. For example, an ADSL line, an optical fiber line, a provider dedicated line, a CATV line, etc. may be connected. However, for convenience of explanation, two types of IPs of the provider A company 12 and another provider B company 13 are connected to the IP telephone line connection terminal portion 11. Assume that a telephone line is connected.

  A telephone connection terminal section 9 for connecting a general telephone set 10, a dial recognition section 2 for recognizing a dial from the general telephone set 10, a dial transmission section 4 for transmitting a telephone number to an IP telephone provider line, and a hook section 5 for performing a hook operation A dial storage unit 7 for storing a dial from the dial recognition unit 2; an IP telephone number storage unit 8 for storing number data for each IP telephone provider; a telephone connection terminal unit 9 and an IP telephone line connection terminal unit 11; It comprises a switching unit 3 for switching connection and a control unit 6 for controlling each unit.

  The switching adapter 1 is configured such that the IP telephone line connection terminal unit 11 and the telephone connection unit 9 are connected via the switching unit 3. Since it is in a standby state now, the telephone connection terminal unit 9 and the IP line connection terminal unit 11 are disconnected by the switching unit 3.

  When a user tries to use an IP phone and raises the handset of the general telephone 10, the control unit 6 operates a DT (dial tone) generation unit 14 in the switching adapter 1 to send DT to the telephone, and the switching adapter. 1 shifts to a state of receiving a dial number from the telephone.

  The user is prompted to dial by listening to the DT, and dials the destination IP telephone number from the general telephone 10. The dial number is transmitted as a push signal (PB signal) or a dial pulse signal (DP signal) from the general telephone 10 to the dial recognition unit 2 in the switching adapter 1 through the telephone connection terminal unit 9.

The control unit 6 stores the telephone number recognized by the dial recognition unit 2 in the dial storage unit 7. Generally, the data is stored after being converted into a hexadecimal number, but is not particularly limited.
Next, the control unit 6 collates with the IP telephone provider number stored in the IP telephone number storage unit 8.

  In general, the IP telephone number is composed of 11 digits, and the IP telephone number is assigned differently for each provider, and it is possible to easily determine which provider the other party is based on. Specifically, as shown in FIG. 2, if the allocation for each provider is stored in the IP telephone number storage unit 8 as an IP telephone number provider table, it is possible to determine which provider is based on the number.

  When it is determined that the corresponding IP telephone provider is the same as the IP telephone provider A company 12 connected to the switching adapter 1, the control unit drives the hook section 5 to which the IP telephone provider A company 12 is connected to perform a hook operation. I do. In this state, since the switching unit 3 is not yet operated, the general telephone 10 side and the IP telephone connection terminal unit 11 are disconnected.

  After hooking, a dial request DT (dial tone) arrives from IP phone provider A 12. Since DT is generally a continuous sound of 400 Hz, it can be easily recognized by the switching adapter 1. That is, it can be determined whether the IP telephone provider A company 12 is operating normally or is simply disconnected. It may have a function of forcibly selecting another IP telephone provider B as a line failure, such as when DT does not arrive.

  Also, depending on the provider, it may be an intermittent sound or other frequency, so when recognizing DT, a recognition method suitable for the provider may be taken.

  After recognizing the DT from the IP telephone line side, the number in the dial storage unit 7 is taken out, and the dial transmission unit 4 connected to the IP telephone provider A company 12 is operated to perform dialing.

  The dial sending unit 4 dials with either a push signal or a dial pulse signal. However, since the dial sending unit 4 may be different for each IP telephone provider, the dial sending unit 4 sends the dial by a dialing method suitable for the selected provider. For example, if the provider A company is a dial pulse signal and the provider B company is a push signal, the control unit controls the dial transmission unit according to the provider line and performs dial transmission. However, it is not always necessary to recognize the DT, and dial transmission may be performed after a certain time has elapsed after the hook operation.

  After dialing out to the provider line, the relay switch in the switching unit 3 is driven to connect the IP telephone connection terminal unit 11 to which the IP telephone provider A company 12 is connected and the telephone connection terminal unit 9.

  After that, the IP telephone provider starts calling the other party's telephone terminal or communication terminal, and if the other party's telephone or communication terminal apparatus responds, communication by IP telephone between the same providers is established.

  In the embodiment, the determination is made after the IP telephone number is stored and dialed out. However, the determination is not necessarily made after the telephone number from the general telephone 10 is stored up to the final number. When the IP telephone provider can be determined, the IP telephone line may be hooked and dials may be sequentially transmitted to connect the IP telephone line and the general telephone 10. In this case, dial transmission becomes faster and usability is improved.

  As described above, according to the present invention, a call between IP telephones installed in an IP telephone provider is constructed, and a call charge can be easily reduced. If the destination IP telephone number corresponds to provider B company, the same procedure as described above may be performed on the line of provider B company 13.

  If the same line network is not connected to the other party's IP phone provider, it is possible to steadily reduce the charge by setting the IP telephone provider line or general line where the call charge is low in advance. Is possible. In addition, since the caller can use it without being aware of it, it is easy to use and contributes to society.

  In the embodiment, a telephone call is made from a general telephone. However, if the telephone connection terminal unit 9 is connected to a main unit of a PBX (exchange) or a key telephone, the communication cost can be reduced for each company.

  Furthermore, it goes without saying that the same effect can be obtained by connecting a non-telephone terminal such as a fax machine or a communication terminal such as a video phone to the telephone connection terminal unit 9.

According to the second aspect of the present invention, when the charge varies depending on the time zone or day of the week, the provider line that can reduce the call charge most depending on the time and day of the week is automatically selected and transmitted.
In this case, the same effect as in the first aspect can be obtained.

  FIG. 1 is a block diagram of an embodiment of the present invention.   FIG. 2 is an explanatory diagram of the IP telephone number provider table of the present invention.
