Description

図示するように、本実施形態のＩＰ電話機１０1〜１０4は、例えばＩＥＥＥ８０２．３に基づくＬＡＮ３０と接続するためのＬＡＮインターフェース部１０１と、ハンドセット等の音声入出力装置や、ダイヤルボタン等を備える操作パネルと接続するための入出力インターフェース部１０２と、ＬＡＮインターフェース部１０１を介してＬＡＮ３０と送受するパケット（ＩＰパケット）を処理するＩＰ処理部１０３と、ＩＰ処理部１０３およびＬＡＮインターフェース部１０１を介して、ＬＡＮ３０に接続されたＤＨＣＰサーバ２０にアクセスし、自身のＩＰアドレスを入手するＤＨＣＰ処理部１０４と、ＳＩＰ等の呼制御プロトコルを使用して呼制御を行なう呼制御処理部１０５と、ＲＴＰを使用してＩＰ処理部１０３および入出力インターフェース部１０２間の通話信号の中継を行なうＲＴＰ処理部１０６と、入出力インターフェース部１０２を介して操作パネルから操作者の指示を受け付ける指示受付部１０７と、を有する。 As illustrated, the IP telephones 10 1 to 10 4 of the present embodiment are, for example, IEEE 802. 1. 3 through the LAN interface unit 101 for connection to the LAN 30 based on the third embodiment, an input / output interface unit 102 for connection to an audio input / output device such as a handset, and an operation panel provided with dial buttons etc. The DHCP server 20 connected to the LAN 30 is accessed via the IP processing unit 103 that processes packets (IP packets) transmitted to and received from the LAN 30, the IP processing unit 103, and the LAN interface unit 101, and the own IP address is obtained. The call processing is relayed between the IP processing unit 103 and the input / output interface unit 102 using the DHCP processing unit 104, the call control processing unit 105 for performing call control using a call control protocol such as SIP, and the like. RTP processor 106, input / output Having an instruction reception unit 107 that receives an instruction from the operation panel of the operator via the over the face portion 102, a.

図示するように、本実施形態のコールマネージャ４０は、例えばＩＥＥＥ８０２．３に基づくＬＡＮ３０と接続するためのＬＡＮインターフェース部４０１と、ＬＡＮインターフェース部４０１を介してＬＡＮ３０と送受するパケット（ＩＰパケット）を処理するＩＰ処理部４０２と、ＩＰ処理部４０２およびＬＡＮインターフェース部４０１を介して、ＳＩＰ等の呼制御プロトコルを使用して、ＩＰ電話機１０’1〜１０’4の代わりに、つまりプロキシサーバとして呼制御を行なう呼制御処理部４０３と、を有する。なお、コールマネージャ４０のＩＰアドレス（ここでは、１９２．１．１８．２）は固定である。 As illustrated, the call manager 40 of this embodiment is, for example, IEEE 802. A LAN interface unit 401 for connecting to the LAN 30 based on No. 3; an IP processing unit 402 that processes packets (IP packets) transmitted to and received from the LAN 30 via the LAN interface unit 401; an IP processing unit 402 and a LAN interface unit 401 through, with using a call control protocol such as SIP, instead of the IP telephone 10 '1-10' 4, i.e. a call control processing unit 403 that performs call control as a proxy server, a. The IP address of the call manager 40 (here, 192.1.18.2) is fixed.

例えば、上記の各実施形態では、ＩＰ電話システムをＩＥＥＥ８０２．３に基づくＬＡＮ上に構築した場合を例にとり説明したが、本発明のＩＰ電話システムは、その他のＷＡＮやイントラネット等、様々なネットワーク上に構築することが可能である。
For example, in each of the above embodiments, the IP telephone system is IEEE802. Although the case of building on the LAN based on No. 3 has been described as an example, the IP telephone system of the present invention can be built on various networks such as other WANs and intranets.
