To solve a problem in which it is difficult to set the jitter buffer capacity to reflect the communication status of each call.SOLUTION: A call relay device according to an embodiment includes a delay analysis unit 12 that analyzes the delay amount of voice data received from an off-premises terminal that performs voice communication via a public communication network and generates delay information, a jitter buffer correction control unit 11 that generates a jitter buffer correction table that associates delay information with terminal position information that indicates the position of the off-premises terminal 20 that is engaged in a call, and that controls the capacity of the jitter buffer on the basis of the jitter buffer correction table, and an audio processing unit 13 that receives audio data via a jitter buffer, performs decoding processing on the audio data, and transmits the audio to a local terminal 30 that belongs to the own device.SELECTED DRAWING: Figure 1 【課題】従来の通話中継装置は、個々の通話の通信状況を反映したジッタバッファ容量とすることが困難である問題があった。【解決手段】一実施の形態にかかる通話中継装置は、公衆通信網を介して音声通信を行う構外端末から受信した音声データの遅延量を解析して遅延情報を生成する遅延解析部１２と、遅延情報と通話中の構外端末２０の位置を示す端末位置情報とを関連付けたジッタバッファ補正テーブルを生成し、ジッタバッファ補正テーブルに基づきジッタバッファの容量を制御するジッタバッファ補正制御部１１と、ジッタバッファを介して音声データを受信し、音声データに対して復号処理を行い、自機に帰属する構内端末３０に音声を伝送する音声処理部１３と、を有する。【選択図】図１
