See --help for a list of available flags and their syntax
For example, sngrep can be used to view SIP packets from a pcap file, also applying filters
sngrep -I file.pcap host 192.168.1.1 and port 5060
or live capturing, saving packets to a new file
sngrep -d eth0 -O save.pcap port 5060 and udp
You can configure some options using sngreprc file
