無線ＬＡＮの通話圏外にある無線ＬＡＮデュアル端末に対して呼が発せられたときに、外線を介して無線ＬＡＮデュアル端末に呼を転送するサービスにおいては、転送される呼は転送時に捕捉された外線の電話番号を公衆網で付与されて無線ＬＡＮデュアル端末に着信する。着信時、無線ＬＡＮデュアル端末の表示画面には当該外線の電話番号が表示される。   In a service for transferring a call to a wireless LAN dual terminal via an external line when a call is made to the wireless LAN dual terminal outside the wireless LAN communication range, the transferred call is an external line captured at the time of transfer Are received by the public network and received at the wireless LAN dual terminal. When an incoming call is received, the telephone number of the outside line is displayed on the display screen of the wireless LAN dual terminal.

しかしながら、社内にある電話機から内線を利用して発した呼であっても、社外にある電話機から外線を利用して発した呼であっても、無線ＬＡＮデュアル端末の表示画面には転送時に捕捉された外線の電話番号が表示されるため、着信時に発信者が社内の者であるか社外の顧客であるのかを判別することができず、電話応答時に発信者に応じた適切な対応を即座にとることができないという問題点があった。また、他の顧客への対応時や社外での会議中などの多忙時であっても、実際に電話応答するまで呼の発信者が社内の者であるのか社外の顧客であるのかを知ることができないという問題点があった。   However, even if the call originates from a telephone in the office using an extension line or the call originates from a telephone outside the office using an external line, it is captured on the display screen of the wireless LAN dual terminal at the time of transfer. Because the phone number of the outside line is displayed, it is not possible to determine whether the caller is an in-house person or an external customer at the time of incoming call. There was a problem that could not be taken. Also, know whether the caller is an internal or external customer until you actually answer the phone even when you are busy, such as when dealing with other customers or during an external meeting. There was a problem that could not.

本発明は上記した如き問題点に鑑みてなされたものであって、無線ＬＡＮの通話圏外にある無線ＬＡＮデュアル端末に対して呼を転送したときに、呼の発信者が社内の者であるのか社外の顧客であるのかを無線ＬＡＮデュアル端末の使用者が電話応答前に知ることができる装置を提供することを目的とする。   The present invention has been made in view of the above-described problems, and when a call is transferred to a wireless LAN dual terminal outside the wireless LAN communication area, is the call originator an in-house person? It is an object of the present invention to provide an apparatus that enables a user of a wireless LAN dual terminal to know whether a customer is outside the company before answering a call.

本発明による呼転送装置は、無線ＬＡＮ内線を介しての通話路設定手段と公衆網外線を介しての通話路設定手段とを備えた無線ＬＡＮデュアル端末と、前記無線ＬＡＮデュアル端末との呼接続要求をなす呼を発信する呼発信手段を備えた電話機と、前記無線ＬＡＮデュアル端末が前記無線ＬＡＮ内線を介しての通話路設定圏外にある場合に前記呼に応じて前記公衆網外線を捕捉しこれを介する通話路を設定して前記電話機と前記無線ＬＡＮデュアル端末とを呼接続する呼接続部を含む構内交換機と、を含む呼転送装置であって、前記構内交換機は、前記呼の発信種別を識別し前記呼接続部をして前記発信種別毎に予め対応付けられている公衆網外線を捕捉せしめる呼接続制御部を含むことを特徴とする。   A call transfer apparatus according to the present invention comprises a wireless LAN dual terminal comprising a speech path setting means via a wireless LAN extension and a speech path setting means via a public network external line, and a call connection between the wireless LAN dual terminals. A telephone having call transmission means for transmitting a call that makes a request; and when the wireless LAN dual terminal is outside a communication path setting area via the wireless LAN extension, captures the public network outside line according to the call. A private branch exchange including a call connection unit for setting a speech path through the telephone and connecting the telephone and the wireless LAN dual terminal to each other, wherein the private branch exchange includes a call transmission type. And a call connection control unit that captures a public network outside line that is associated in advance with each call type by using the call connection unit.

以下、本発明に係る実施例について添付の図面を参照しつつ詳細に説明する。   Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

図１は本発明による呼転送装置を公衆網１４などと共に表すブロック図である。呼転送装置は電話機１及び２と、構内交換機５と、無線ＬＡＮデュアル端末１５とを含む。   FIG. 1 is a block diagram showing a call transfer apparatus according to the present invention together with a public network 14 and the like. The call transfer apparatus includes telephones 1 and 2, private branch exchange 5, and wireless LAN dual terminal 15.

電話機１及び２の各々は無線ＬＡＮデュアル端末１５との呼接続要求をなす呼を発信する呼発信手段を備える。電話機１は発信側外線３を介して構内交換機５内の呼接続部６に接続されている。電話機２は内線４を介して構内交換機５内の呼接続部６に接続されている。なお、電話機１及び２の他にも、これらと同様の機能を有する電話機が複数個、含まれていても良い。   Each of the telephones 1 and 2 includes call transmission means for transmitting a call for making a call connection request with the wireless LAN dual terminal 15. The telephone 1 is connected to the call connection unit 6 in the private branch exchange 5 via the outgoing side outside line 3. The telephone 2 is connected to a call connection unit 6 in the private branch exchange 5 through an extension 4. In addition to the telephones 1 and 2, a plurality of telephones having the same functions as these may be included.

構内交換機５は呼接続部６と、呼接続制御部７とを含む。   The private branch exchange 5 includes a call connection unit 6 and a call connection control unit 7.

呼接続部６は無線ＬＡＮデュアル端末１５が無線ＬＡＮ内線１０を介しての通話路設定圏８内にある場合に、電話機１及び２のいずれかより発信された呼に応じて、無線ＬＡＮアクセスポイント９及び無線ＬＡＮ内線１０を介する通話路を設定して、呼発信のあった電話機（電話機１及び２のいずれか）と無線ＬＡＮデュアル端末１５とを呼接続する。   When the wireless LAN dual terminal 15 is in the communication path setting area 8 via the wireless LAN extension 10, the call connection unit 6 is connected to the wireless LAN access point according to the call transmitted from either the telephone 1 or 2. 9 and the wireless LAN extension 10 are set, and the telephone (either one of the telephones 1 and 2) that has made a call is connected to the wireless LAN dual terminal 15 by call connection.

また、呼接続部６は無線ＬＡＮデュアル端末１５が無線ＬＡＮ内線１０を介しての通話路設定圏８外にある場合に、電話機１及び２のいずれかより発信された呼に応じて、公衆網１４に接続されている公衆網外線１１〜１３の内のいずれかを捕捉し、これを介する通話路を設定して、呼発信のあった電話機（電話機１及び２のいずれか）と無線ＬＡＮデュアル端末１５とを呼接続する。   Further, when the wireless LAN dual terminal 15 is outside the communication path setting area 8 via the wireless LAN extension 10, the call connection unit 6 responds to a call originated from either the telephone 1 or 2 according to the public network. 14 is connected to a telephone network (either one of the telephones 1 and 2) and a wireless LAN dual is set. The terminal 15 is call-connected.

呼接続制御部７は電話機１及び２のいずれかより発信された呼の発信種別を識別し、呼接続部６をして発信種別毎に予め対応付けられている公衆網外線１１〜１３の内のいずれかを捕捉せしめる。呼接続制御部７は呼接続部６をして捕捉せしめる公衆網外線１１〜１３の各々と発信種別の各々とを予め対応付けておく。この対応付けに応じて呼接続部６は発信種別毎に公衆網外線１１〜１３のいずれかを捕捉する。   The call connection control unit 7 identifies the call origination type of a call originated from either the telephone set 1 or 2, and uses the call connection unit 6 to select one of the public network outside lines 11 to 13 previously associated with each call origination type. Let's catch either. The call connection control unit 7 associates each of the public network outside lines 11 to 13 captured by the call connection unit 6 with each of the transmission types. In response to this association, the call connection unit 6 captures one of the public network outside lines 11 to 13 for each transmission type.

第１の発信種別は、無線ＬＡＮ内線１０を介した通話路設定による呼接続を要求する呼が発信側外線３を経由してなされた発信である。これは例えば社外の顧客が無線ＬＡＮデュアル端末１５の内線番号に呼を発信した場合などに相当する。この場合、呼接続部６は公衆網外線１１を捕捉する。   The first call type is a call that is made via the caller-side external line 3 for a call connection requesting call path setting via the wireless LAN extension 10. This corresponds to, for example, a case where a customer outside the company sends a call to the extension number of the wireless LAN dual terminal 15. In this case, the call connection unit 6 captures the public network outside line 11.

第２の発信種別は、無線ＬＡＮ内線１０を介した通話路設定による呼接続を要求する呼が内線４を経由してなされた発信である。これは例えば社内の従業員が無線ＬＡＮデュアル端末１５の内線番号に呼を発信した場合などに相当する。この場合、呼接続部６は公衆網外線１２を捕捉する。   The second call type is a call made through the extension line 4 for requesting a call connection by setting a communication path via the wireless LAN extension line 10. This corresponds to, for example, a case where a company employee sends a call to the extension number of the wireless LAN dual terminal 15. In this case, the call connection unit 6 captures the public network outside line 12.

第３の発信種別は、公衆網外線１１〜１３のいずれかを介した通話路設定による呼接続を要求する呼が内線４を経由してなされた発信である。これは例えば社内の従業員が無線ＬＡＮデュアル端末１５の携帯端末番号に呼を発信した場合などに相当する。この場合、呼接続部６は公衆網外線１３を捕捉する。   The third call type is a call made through the extension line 4 for requesting a call connection by setting a communication path via any one of the public network outside lines 11 to 13. This corresponds to, for example, a case where an in-house employee sends a call to the mobile terminal number of the wireless LAN dual terminal 15. In this case, the call connection unit 6 captures the public network outside line 13.

呼接続制御部７は例えば電話機１及び２のいずれかより発信された呼に含まれている電話番号などに基づいて発信種別を識別する。また、呼接続制御部７は発信された呼に含まれている電話番号以外の何らかの識別子に基づいて発信種別を識別しても良い。   The call connection control unit 7 identifies the call type based on, for example, a telephone number included in a call sent from either the telephone 1 or 2. Further, the call connection control unit 7 may identify the transmission type based on some identifier other than the telephone number included in the transmitted call.

公衆網外線１１〜１３の各々は公衆網１４に接続されている。公衆網外線１１〜１３の各々には通常、互いに異なる電話番号が割り当てられている。この場合、無線ＬＡＮデュアル端末１５に公衆網外線１１を介して着信する呼（以下、外線転送着信呼と称する）、公衆網外線１２を介して着信する呼（以下、内線転送着信呼と称する）、及び、公衆網外線１３を介して着信する呼（以下、内線直通着信呼と称する）の各々には、公衆網１４において互いに異なる電話番号が付与される。   Each of the public network outside lines 11 to 13 is connected to the public network 14. Each of the public network outside lines 11 to 13 is usually assigned a different telephone number. In this case, a call that arrives at the wireless LAN dual terminal 15 via the public network outside line 11 (hereinafter referred to as an external line transfer incoming call) and a call that arrives via the public network outside line 12 (hereinafter referred to as an internal line transfer incoming call) In addition, a different telephone number is assigned to each of the calls received through the public network outside line 13 (hereinafter referred to as an extension direct incoming call) in the public network 14.

無線ＬＡＮデュアル端末１５は無線ＬＡＮ内線１０を介しての通話路設定手段と公衆網外線１１〜１３を介しての通話路設定手段とを備える。無線ＬＡＮ内線１０を介しての通話路設定圏８内にある無線ＬＡＮデュアル端末１５は、無線ＬＡＮ内線１０を介する通話路を設定する。無線ＬＡＮ内線１０を介しての通話路設定圏８外にある無線ＬＡＮデュアル端末１５は、公衆網外線１１〜１３を介する通話路を設定する。本実施例における無線ＬＡＮデュアル端末１５は無線ＬＡＮ内線１０を介しての通話路設定圏８外にあるとする。   The wireless LAN dual terminal 15 includes speech path setting means via the wireless LAN extension 10 and speech path setting means via the public network outside lines 11 to 13. The wireless LAN dual terminal 15 in the communication path setting area 8 via the wireless LAN extension 10 sets a communication path via the wireless LAN extension 10. The wireless LAN dual terminal 15 located outside the communication path setting area 8 via the wireless LAN extension 10 sets a communication path via the public network outside lines 11 to 13. It is assumed that the wireless LAN dual terminal 15 in this embodiment is outside the speech path setting area 8 via the wireless LAN extension 10.

無線ＬＡＮデュアル端末１５は公衆網外線１１〜１３を介する通話路から到来した呼に含まれている電話番号を表示する表示部１６を含む。また、無線ＬＡＮデュアル端末１５は電話番号毎に文字列を対応付ける機能を備え、表示部１６は電話番号を表示する代わりに文字列を表示する機能を備える。   The wireless LAN dual terminal 15 includes a display unit 16 for displaying a telephone number included in a call arriving from a communication path via the public network outside lines 11 to 13. The wireless LAN dual terminal 15 has a function of associating a character string for each telephone number, and the display unit 16 has a function of displaying a character string instead of displaying a telephone number.

図２は無線ＬＡＮデュアル端末１５が無線ＬＡＮ内線１０を介しての通話路設定圏８外にある場合になされる呼転送処理を表すシーケンス図である。以下に図２を参照しつつ、電話機１が呼を発信した場合の呼転送処理について説明する。   FIG. 2 is a sequence diagram showing call transfer processing performed when the wireless LAN dual terminal 15 is outside the communication path setting area 8 via the wireless LAN extension 10. The call transfer process when the telephone 1 makes a call will be described below with reference to FIG.

先ず、電話機１が発信側外線３を介して無線ＬＡＮデュアル端末１５との呼接続要求をなす呼を発信する（Ｓ２１）。当該呼は無線ＬＡＮ内線１０を介した通話路設定による呼接続を要求する呼、すなわち、例えば社外の顧客が無線ＬＡＮデュアル端末１５の内線番号にむけて発信した呼である。発信された呼は構内交換機５の呼接続部６に着信する（Ｓ２２）。このとき、無線ＬＡＮデュアル端末１５は無線ＬＡＮ内線１０を介しての通話路設定圏８外にあるため、呼接続制御部７は呼に含まれている電話番号などに基づいて呼の発信種別を識別する（Ｓ２３）。無線ＬＡＮ内線１０を介した通話路設定による呼接続を要求する呼が発信側外線３を経由してなされた発信であることから、呼接続制御部７は呼接続部６をして公衆網外線１１を捕捉せしめる（Ｓ２４）。続いて呼接続部６は公衆網外線１１を介して無線ＬＡＮデュアル端末１５に呼を発信する（Ｓ２５）。当該呼（外線転送着信呼）が無線ＬＡＮデュアル端末１５に着信し（Ｓ２６）、電話機１と無線ＬＡＮデュアル端末１５とが呼接続される。無線ＬＡＮデュアル端末１５に外線転送着信呼が着信したら、表示部１６は公衆網１４において外線転送着信呼に付与された電話番号若しくは電話番号に予め対応付けられた文字列を表示する（Ｓ２７）。ここでの文字列は例えば「外線転送」などである。   First, the telephone 1 sends a call for making a call connection request with the wireless LAN dual terminal 15 via the calling side outside line 3 (S21). The call is a call requesting a call connection by setting a communication path via the wireless LAN extension 10, that is, a call made by, for example, an outside customer to the extension number of the wireless LAN dual terminal 15. The transmitted call arrives at the call connection unit 6 of the private branch exchange 5 (S22). At this time, since the wireless LAN dual terminal 15 is outside the communication path setting area 8 via the wireless LAN extension 10, the call connection control unit 7 determines the call origination type based on the telephone number included in the call. Identify (S23). Since the call requesting the call connection by setting the communication path via the wireless LAN extension 10 is an outgoing call made via the caller outside line 3, the call connection control unit 7 uses the call connection unit 6 as a public network outside line. 11 is captured (S24). Subsequently, the call connection unit 6 sends a call to the wireless LAN dual terminal 15 via the public network outside line 11 (S25). The call (outside line transfer incoming call) arrives at the wireless LAN dual terminal 15 (S26), and the telephone 1 and the wireless LAN dual terminal 15 are call-connected. When an outside line transfer incoming call is received at the wireless LAN dual terminal 15, the display unit 16 displays a telephone number assigned to the outside line transfer incoming call in the public network 14 or a character string previously associated with the telephone number (S27). The character string here is "external line transfer", for example.

次に図２を参照しつつ、電話機２が呼を発信した場合の呼転送処理について説明する。先ず、電話機２が内線４を介して無線ＬＡＮデュアル端末１５との呼接続要求をなす呼を発信する（Ｓ２１）。当該呼は無線ＬＡＮ内線１０を介した通話路設定による呼接続を要求する呼、すなわち、例えば社内の従業員が無線ＬＡＮデュアル端末１５の内線番号にむけて発信した呼である。発信された呼は構内交換機５の呼接続部６に着信する（Ｓ２２）。このとき、無線ＬＡＮデュアル端末１５は無線ＬＡＮ内線１０を介しての通話路設定圏８外にあるため、呼接続制御部７は呼に含められている電話番号などに基づいて呼の発信種別を識別する（Ｓ２３）。無線ＬＡＮ内線１０を介した通話路設定による呼接続を要求する呼が内線４を経由してなされた発信であることから、呼接続制御部７は呼接続部６をして公衆網外線１２を捕捉せしめる（Ｓ２４）。続いて呼接続部６は公衆網外線１２を介して無線ＬＡＮデュアル端末１５に呼を発信する（Ｓ２５）。当該呼（内線転送着信呼）が無線ＬＡＮデュアル端末１５に着信し（Ｓ２６）、電話機２と無線ＬＡＮデュアル端末１５とが呼接続される。無線ＬＡＮデュアル端末１５に内線転送着信呼が着信したら、表示部１６は公衆網１４において内線転送着信呼に付与された電話番号若しくは電話番号に予め対応付けられた文字列を表示する（Ｓ２７）。ここでの文字列は例えば「内線転送」などである。   Next, a call transfer process when the telephone 2 sends a call will be described with reference to FIG. First, the telephone 2 transmits a call for making a call connection request with the wireless LAN dual terminal 15 via the extension 4 (S21). The call is a call requesting a call connection by setting a communication path via the wireless LAN extension 10, that is, a call made by, for example, an in-house employee to the extension number of the wireless LAN dual terminal 15. The transmitted call arrives at the call connection unit 6 of the private branch exchange 5 (S22). At this time, since the wireless LAN dual terminal 15 is outside the communication path setting area 8 via the wireless LAN extension 10, the call connection control unit 7 determines the call origination type based on the telephone number included in the call. Identify (S23). Since the call requesting the call connection by setting the communication path via the wireless LAN extension 10 is an outgoing call made via the extension 4, the call connection control unit 7 uses the call connection unit 6 to connect the public network outside line 12. Capture (S24). Subsequently, the call connection unit 6 sends a call to the wireless LAN dual terminal 15 via the public network outside line 12 (S25). The call (extension transfer incoming call) arrives at the wireless LAN dual terminal 15 (S26), and the telephone 2 and the wireless LAN dual terminal 15 are call-connected. When the extension transfer incoming call is received at the wireless LAN dual terminal 15, the display unit 16 displays a telephone number assigned to the extension transfer incoming call or a character string previously associated with the telephone number in the public network 14 (S27). The character string here is, for example, “extension transfer”.

同様に図２を参照しつつ、上述したのとは異なる発信種別にて電話機２が呼を発信した場合の呼転送処理について説明する。先ず、電話機２が内線４を介して無線ＬＡＮデュアル端末１５との呼接続要求をなす呼を発信する（Ｓ２１）。当該呼は公衆外線１１〜１３のいずれかを介した通話路設定による呼接続を要求する呼、すなわち、例えば社内の従業員が無線ＬＡＮデュアル端末１５の携帯端末番号にむけて発信した呼である。発信された呼は構内交換機５の呼接続部６に着信する（Ｓ２２）。呼接続制御部７は呼に含まれる電話番号などに基づいて呼の発信種別を識別する（Ｓ２３）。公衆外線１１〜１３のいずれかを介した通話路設定による呼接続を要求する呼が内線４を経由してなされた発信であることから、呼接続制御部７は呼接続部６をして公衆網外線１３を捕捉せしめる（Ｓ２４）。続いて呼接続部６は公衆網外線１３を介して無線ＬＡＮデュアル端末１５に呼を発信する（Ｓ２５）。当該呼（内線直通着信呼）が無線ＬＡＮデュアル端末１５に着信し（Ｓ２６）、電話機２と無線ＬＡＮデュアル端末１５とが呼接続される。無線ＬＡＮデュアル端末１５に内線直通着信呼が着信したら、表示部１６は公衆網１４において内線直通着信呼に付与された電話番号若しくは電話番号に予め対応付けられた文字列を表示する（Ｓ２７）。ここでの文字列は例えば「内線直通」などである。   Similarly, with reference to FIG. 2, a call transfer process when the telephone set 2 transmits a call with a transmission type different from that described above will be described. First, the telephone 2 sends a call for making a call connection request with the wireless LAN dual terminal 15 via the extension 4 (S21). The call is a call requesting a call connection by setting a communication path via any one of the public external lines 11 to 13, that is, a call made by, for example, an in-house employee to the mobile terminal number of the wireless LAN dual terminal 15. . The transmitted call arrives at the call connection unit 6 of the private branch exchange 5 (S22). The call connection control unit 7 identifies the call origination type based on the telephone number included in the call (S23). Since the call requesting the call connection by setting the communication path via any one of the public external lines 11 to 13 is an outgoing call made via the extension line 4, the call connection control unit 7 uses the call connection unit 6 as a public call. The outside line 13 is captured (S24). Subsequently, the call connection unit 6 sends a call to the wireless LAN dual terminal 15 via the public network outside line 13 (S25). The call (extension direct incoming call) arrives at the wireless LAN dual terminal 15 (S26), and the telephone set 2 and the wireless LAN dual terminal 15 are call-connected. When an extension direct incoming call is received at the wireless LAN dual terminal 15, the display unit 16 displays a telephone number assigned to the extension direct incoming call or a character string previously associated with the telephone number in the public network 14 (S27). The character string here is, for example, “extension direct”.

表示部１６は例えば「０３−７６２９−９７２１」の如く外線転送着信呼に付与されている電話番号を表示しても良いし、「外線転送」の如く電話番号に予め対応付けてある文字列を表示しても良い。外線転送着信呼、内線転送着信呼及び内線直通着信呼の各々には公衆網１４において互いに異なる電話番号が付与されるため、無線ＬＡＮデュアル端末１５の利用者は、表示部１６に表示される電話番号を視認することにより、呼の発信者が社内の者であるのか社外の顧客であるのかを電話応答前に知ることができる。また、電話番号毎に例えば「外線転送」、「内線転送」及び「内線直通」などの文字列を対応付けておけば、電話番号に対応付けられた文字列が表示部１６に表示されるため、無線ＬＡＮデュアル端末１５の利用者が電話番号を覚えていなくとも、電話応答前に発信者を知ることができる。   For example, the display unit 16 may display a telephone number assigned to an incoming call for an outside line transfer such as “03-7629-9721”, or a character string previously associated with the telephone number such as “outside line transfer”. You may display. Since each of the external line transfer incoming call, the internal line transfer incoming call, and the extension direct incoming call is given a different telephone number in the public network 14, the user of the wireless LAN dual terminal 15 can make a call displayed on the display unit 16. By visually recognizing the number, it is possible to know whether the caller is an in-house person or an outside customer before answering the call. Further, if a character string such as “external line transfer”, “extension transfer”, and “extension direct communication” is associated with each telephone number, the character string associated with the telephone number is displayed on the display unit 16. Even if the user of the wireless LAN dual terminal 15 does not remember the telephone number, the caller can be known before answering the telephone.

上記した如く、構内交換機５は無線ＬＡＮデュアル端末１５が無線ＬＡＮ内線１０を介しての通話路設定圏８外にある場合に、電話機１及び２のいずれかより発せられた呼に応じて、公衆網外線１１〜１３のいずれかを捕捉し、これを介する通話路を設定して呼を発した電話機（電話機１及び２のいずれか）と無線ＬＡＮデュアル端末１５とを呼接続する呼接続部６に加えて、当該呼の発信種別を識別し、呼接続部６をして発信種別毎に予め対応付けられている公衆網外線１１〜１３のいずれかを捕捉せしめる呼接続制御部７を含む。呼転送装置が無線ＬＡＮ内線１０を介しての通話路設定圏８外にある無線ＬＡＮデュアル端末１５に対して呼を転送したときに、外線転送着信呼、内線転送着信呼及び内線直通着信呼の各々には公衆網１４において互いに異なる電話番号が付与されるため、表示部１６に表示される電話番号を視認することにより、呼の発信者が社内の者であるのか社外の顧客であるのかを無線ＬＡＮデュアル端末１５の使用者が電話応答前に知ることができる。そのため、無線ＬＡＮデュアル端末１５の使用者は電話応答時に発信者に応じた適切な対応を即座にとることができる。また、無線ＬＡＮデュアル端末１５の使用者が他の顧客への対応や社外での会議などによって多忙である場合には、発信者が誰であるかを電話応答前に確認して電話応答しないという選択ができるようになる。   As described above, when the wireless LAN dual terminal 15 is outside the communication path setting area 8 via the wireless LAN extension 10, the private branch exchange 5 responds to a call made from either one of the telephones 1 and 2 according to the call. A call connection unit 6 that captures any of the outside lines 11 to 13, sets up a communication path via the outside line 11 to 13, and makes a call connection between the telephone (one of the telephones 1 and 2) and the wireless LAN dual terminal 15. In addition, it includes a call connection control unit 7 that identifies the call origination type of the call, and causes the call connection unit 6 to capture any of the public network outside lines 11 to 13 previously associated with each call origination type. When the call transfer device transfers a call to the wireless LAN dual terminal 15 outside the communication path setting area 8 via the wireless LAN extension 10, an external transfer incoming call, an extension transfer incoming call, and an extension direct incoming call Since different telephone numbers are assigned to each in the public network 14, by checking the telephone number displayed on the display unit 16, whether the caller is an in-house person or an outside customer is identified. The user of the wireless LAN dual terminal 15 can know before answering the call. Therefore, the user of the wireless LAN dual terminal 15 can immediately take an appropriate action according to the caller when answering a call. In addition, when the user of the wireless LAN dual terminal 15 is busy due to dealing with other customers or meetings outside the company, it is confirmed that the caller is confirmed before answering the telephone and the telephone is not answered. You will be able to choose.
