Description

  The present invention relates to a telephone system capable of informing a voice of “who is a telephone addressed to whom” when an incoming call is received.

  As a background art of this technical field, there is Patent Document 1. In this gazette, when a call is received by a telephone shared by a plurality of users, the ring tone is changed to clarify who the telephone is destined for. A system that can respond promptly without bothering is described.

Japanese Patent Laid-Open No. 2-192255

  When a fixed IP phone is shared by multiple people, it is possible to determine who has received a call because the system that displays the caller's phone number on the phone already exists. There is no way to determine who the phone was called. In order to determine who the call was received from, it is necessary for the third party to make a call and respond to the call, so there was a problem that the caller and the third party took time and effort.

  In the method described in Patent Document 1, when the receiver is on a business trip, the third party makes a phone call because the receiver is not at the place of work even if the ring tone is changed to clarify who the phone is. However, it is necessary to respond to the telephone, and the caller and third party take time and effort. In addition, the third party is required twice to notify that the caller has made a call to the desired receiver, or to call the caller again to the desired receiver.

  In order to solve the above problems, a telephone system of the present invention is connected to an IP phone, an information processing terminal, a communication device that connects a plurality of IP phones and information processing terminals to a network, and the communication device via the network. And a management server, and when making a call connection request from the first IP telephone to the second IP telephone, the first IP telephone sets user identification information for identifying a telephone receiver in the call connection request. In addition, when the second IP telephone receives the call connection request, the second IP telephone transmits the receiver identification information included in the call connection request to the management server, and the management server receives the user identification information received from the second IP telephone. It is checked whether the information processing terminal used by the user specified by the second IP phone and the second IP phone are connected to the same communication device, and a call connection request is sent to another IP phone other than the second IP phone. Forward to When the second IP telephone or the other IP telephone that receives the call connection request determines whether or not to call the telephone by using the user identification information included in the call connection request, the user identification information Notify that the call is addressed to the user specified in.

  A fixed IP phone can be notified by voice when a call is received from whom, and it is installed at a business trip destination even when it is not working at a regular work place on a business trip. Because it is possible to inform the fixed IP phone that is close to the recipient of the phone by voice when it receives an incoming call, the desired recipient can use other users' hands. It becomes possible to respond promptly without bothering you.

Display ”),“ <Employee name of company A (A1) (in Roman letters)> calls <Employee name of company B (B1) (in Roman letters)> ”. Make a voice announcement. This announcement may be used as a ring tone, or a ring tone may be sounded together with the announcement.

  If the comparison results of the fixed IP telephone numbers do not match (no in step 1306), the incoming call is transferred to another telephone, and the transfer processing unit 905 transfers the telephone to the telephone number received from the SIP server 203 ( 1309). The processing of the transfer destination fixed IP telephone 101 is processing after step 1304. If the fixed IP phone numbers do not match in this way, the employee of company B (B1) is away from the normal place of work such as working at a business trip destination, and the call transfer is performed by the function of this embodiment. .

  FIG. 12 is a diagram showing processing of the terminal connection destination management server 203 of this embodiment, and is processing subsequent to step 1305 in FIG. The terminal connection destination confirmation unit 503 of the terminal connection destination management server 203 that has received the employee ID 1001 of the employee (B1) and the fixed IP phone number 1003 of the recipient included in the INVITE request from the fixed IP phone (B1) 101 The employee ID 601 of the employee information table 600 is searched using the received employee ID 1001 of the employee (B1), and the corresponding owned PC management ID 603 is acquired. Next, the terminal connection destination confirmation unit 503 searches the owned PC management ID 701 in the PC table 700 using the acquired owned PC management ID 603, and refers to the activation ON / OFF 704 of the matching entry (1401).

  Here, when the activation ON / OFF 704 is OFF, it is considered that the PC 102 of the employee (B1) is not activated. For this reason, the terminal connection destination confirmation unit 503 returns the telephone number of the fixed IP phone (B1) 101 in order to make the incoming call to the fixed IP phone (B1) 101 that has transmitted the employee ID and the fixed IP phone number in step 1305. In this case, the fixed IP telephone number 1003 of the recipient included in the INVITE request is the telephone number of the fixed IP telephone (B1) 101.

  When the activation ON / OFF 704 is ON, the terminal connection destination confirmation unit 503 acquires the island HUBID 705 of the PC table 700 corresponding to the owned PC management ID 603 acquired in step 1401. Then, the terminal connection destination confirmation unit 503 transmits the acquired island HUBID 705 to the destination check unit 504. Simultaneously with this processing, the terminal connection destination confirmation unit 503 searches the fixed IP phone number 801 in the fixed IP phone table 800 using the recipient's fixed IP phone number received from the fixed IP phone (B1) 101 in step 1401. The island HUBID 805 corresponding to this is acquired. Lastly, the terminal connection destination confirmation unit 503 transmits the acquired island HUBID 805 to the destination inspection unit 504 (1402).

  The reason for taking out the island HUBID 705 of the PC (B1) and the island HUBID 805 of the fixed IP telephone (B1) is that the island HUBID 705 and the island HUBID 805 are compared, and if the connection destinations match, the employee of the company B who is the recipient (B1) Can be determined to be working at the place specified by the island HUBID 805 of the fixed IP telephone (B1), and if the connection destination does not match, it is specified by the island HUBID 705 of the business trip destination, that is, the PC (B1). It is because it can be judged that he / she works at the place.

  The destination check unit 504 compares the island HUBID 705 and the island HUBID 805 received from the terminal connection destination check unit 503 in step 1402 and checks whether they match (1404). If they match, the destination check unit 504 transmits the fixed IP phone number 1003 received from the terminal connection destination check unit 503, that is, the phone number of the fixed IP phone (B1) 101, to the telephone reply unit 505 (1405). The telephone reply unit 505 instructs the incoming call determination unit 904 of the fixed IP telephone (B1) 101 to receive the incoming call to the fixed IP telephone number 1003 (the telephone number of the fixed IP telephone (B1) 101) received from the destination check unit 504. (1408).

  If the island HUBIDs 705 and 805 do not match in step 1404, the destination check unit 504 extracts all the entries in the fixed IP phone table 800 in which the island HUBID 705 and the island HUBID 805 of the PC (B1) match, and the fixed IP phone of the entry All numbers 801 are acquired. This process is a process in the case where an employee (B1) of company B who is a telephone receiver is working on a business trip. Further, since the terminal connection destination management server 203 can grasp the base, the floor, and the direction to which the company B employee (B1) PC (B1) is connected, the fixed IP connected to the base, the floor, and the direction. All phone numbers can be identified.

The destination check unit 504 selects the fixed IP telephone (B1) corresponding to the port number 806 of the port closest to the port number 706 of the island HUB 304 to which the PC (B1) 102 is connected from the acquired fixed IP telephone numbers 801. ) 101 fixed IP telephone number 801 is identified (1406), and this is transmitted to the telephone reply unit 505 (1407). This process will be specifically described below. It is assumed that the port number 706 where the employee (B1) PC (B1) 102 is connected to the island HUB 304 is m. However, m is a natural number, and the maximum value of m is the number of ports of the island HUB 304, and varies depending on the model. Also, selected in step 1406, and is connected to the same island HUB304 as PC (B1) 102, a port number 806 which corresponds to the fixed IP telephone number 801 of the at least one or more fixed IP telephone 101 and n _k. However, n is a natural number, and the maximum value of n is the number of ports of the island HUB 304, and differs depending on the model. K indicates the number of fixed IP telephone numbers 801 corresponding to the island HUBID 705 selected in step 7-1, and k = 1, 2, 3,. Further, the port number 806 closest to the port number 706 of the PC (B1) 102 in n _k is represented by n ^* . However, n ^* is a natural number, and the maximum value of n ^* is the number of ports on the island HUB 304, and differs depending on the model.

  Of one or more fixed IP telephones 101 connected to the same island HUB 304 as PC (B1) 102, the port number 806 closest to the port number 706 of PC (B1) 102 is obtained by the following formula. Can do.

In short, the difference between the port numbers is calculated, and the port with the smallest difference is the port that is close in distance. As a premise, a port number is assigned to each port so that the difference between the port numbers of adjacent ports is 1. Then, as shown in Equation 1, a combination of ports with a small difference between port numbers is a combination with a short distance between the ports.

Therefore, the desired fixed IP telephone number 801 is the fixed IP telephone number 801 having the same island HUBID 805 as the island HUBID 705 of the PC (B1) 102 from the fixed IP telephone table 800 and having the port number n ^*. . This desired fixed IP telephone number 801 is a calling number when an employee (B1) of company B is working on a business trip. Then, the telephone reply unit 505 instructs the incoming call determination unit 904 of the fixed IP telephone (B1) 101 to receive the incoming call to the fixed IP telephone number 801 received from the incoming call destination investigation part 504 (1408).
