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 and each
call is saved as pcap dump. Web PHP application (it is not part of open
source sniffer) filters data 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.
