SIPffer

SIPffer (SIP + sniffer): A SIP protocol sniffer for quick and smart troubleshooting.

What's SIPffer

SIPffer is an easy to use command line tool for troubleshooting issues with SIP traffic (switches, proxies, SBCs, VoIP Servers, PBXs, etc..). It comes very handy in high traffic and other noisy environments to do quick and smart diagnostics on remote ends, compared to otherwise heavier and harder to run or install WireShark or other all-purpose traffic analysis tools.

It is distributed under the GPLv3 license.

Features

Filter SIP packets matching Regular Expression.
Custom BPF Filters.
SIP session tracking (option -s or --follow).
Offline analysis of tcpdump (.pcap) capture files.
Filter by SIP method (REGISTER, INVITE, OPTIONS, BYE, etc).
Filter by SIP response (200, 302, 404, etc).

Installing

git clone https://github.com/xenomuta/SIPffer
cd SIPffer

sudo make install

NOTE: SIPffer depends on libpcap (>= 0.8) and libpcre to compile.
