The invention relates to a technical scheme for judging a call direction and a system based on a network packet capturing mode. The technical scheme comprises the following steps: monitoring and capturing a network packet on a first side; analyzing the network packet of the first side, and extracting address information sent and received in the call request signaling; and based on the network packet capturing position, comparing the address information of the call request signaling with the address information of the service provided by the telephone system, and judging the incoming and outgoing directions. The method and the system have the beneficial effects that the incoming and outgoing directions are judged only based on the address information of the service provided by the telephone system through capturing and analyzing the network packet without the interior of the telephone system, so that the efficiency of judging the calling direction is improved. 本发明涉及一种基于网络包抓取方式判断通话方向和系统的技术方案，包括：监听并抓取第一侧的网络包；解析第
