sngrep

sngrep is a tool for displaying SIP calls message flows.

It supports live capture to display realtime SIP packets and can also be used as PCAP viewer.

Prerequisites

• libncurse5 - for UI , windows, panels.
• libpcap - for capturing packets.

Installing

On most systems the commands to build will be the standard atotools procedure:

./configure
make
make install (as root)

If you dont want to use libpcap (because is not available in your system or don't want to install more development libraries), you can use release 0.0.0 available at https://github.com/irontec/sngrep/releases

Usage

sngrep can be used to view SIP packets from a pcap file

sngrep file.pcap

or live capturing

sngrep port 5060 and udp

You can configure some options using a sngreprc file

Frequent Asked Questions

Why a new tool from network filtering?

Don't know. I didn't find any console tool that will display call flows.

Extended Call flow window doesn't work

If you want to make relations between different dialogs (extended callflow) a header must be present in of the dialogs referencing the other one. This header can be X-CID or X-Call-ID and must contain the Call-ID of the other related dialog.
