What is VoIPmonitor ------------------- VoIPmonitor is open source live network packet sniffer which analyze SIP and RTP protocol. It can run as daemon or analyzes already captured pcap files. For each detected VoIP call voipmonitor calculates statistics about loss, burstiness, latency and predicts MOS (Meaning Opinion Score) according to ITU-T G.107 E-model. These statistics are saved to MySQL database and each call is saved as pcap dump. Web PHP application (it is not part of open source sniffer) filters data from database and graphs latency and loss distribution. Voipmonitor also detects improperly terminated calls when BYE or OK was not seen. To accuratly transform latency to loss packets, voipmonitor simulates fixed and adaptive jitterbuffer. Key features ------------ - Fast C++ SIP/RTP packet analyzer - Predicts MOS-LQE score according to ITU-T G.107 E-model - Detailed delay/loss statistics stored to MySQL - Each call is saved as standalone pcap file What is required ---------------- - C and C++ compiler (gcc,g++) - libpcap-dev package >= 0.8 (almost in every linux distribution) - MySQL++ library from http://tangentsoft.net/mysql++/ - zlib ibrary Compile ------- This howto is for Debian Lenny and Etch (for Debian sarge, change libmysqlclient15-dev to libmysqlclient14-dev) apt-get install libpcap-dev libmysqlclient15-dev zlib1g-dev wget http://tangentsoft.net/mysql++/releases/mysql++-3.0.9.tar.gz tar xzf mysql++-3.0.9.tar.gz cd mysql++-3.0.9 ./configure make install ldconfig cd ../voipmonitor make make install MySQL ----- cat cdrtable.sql |mysql databaseName Upgrade from 1.2.X to 1.3 ------------------------- cat cdrtable.sql.1.2.1-1.3 | mysql voipmonitor Upgrade from 1.3.X and 1.4.X to 1.5 ------------------------- cat cdrtable.sql.1.3-1.5 | mysql voipmonitor
