filterpcap

Fast pcap voip filters

This little tool will take in a packet capture and search it for calls containing specific features (i.e. called phone number, SIP call id, or calls containing SIP packets with a certain status code). The found calls will be output to separate files, and zipped if there are more than one file.

Some example usages

# Find calls to 4145341207
filterpcap file.pcap --toNumber=4145341207

# Find call with SIP callId 'xyz'
filterpcap file.pcap --callId=xyz

# Find all calls with SIP packets that have status code 488
filterpcap file.pcap --sipCode=488
