./configure
make
make install (as root)
You can pass following flags to ./configure to enable some features
| configure flag | Feature |

--with-openssl |
Adds OpenSSL support to parse TLS captured messages (req. libssl) |
--with-pcre |
Adds Perl Compatible regular expressions support in regexp fields |
--enable-unicode |

You can find [detailed instructions for some distributions] (https://github.com/irontec/sngrep/wiki/Building) on wiki.
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] (https://github.com/irontec/sngrep/wiki/Configuration) file
