Overview

Step 1: Changing the date format
Step 2: Setup your Network Card
Step 3: Configuring options and starting the packet capture
Step 4: Filtering the SIP protocol
Step 5: Saving results.

First, you will need to install wireshark. You can download wireshark from http://www.wireshark.org/download.html

Wireshark is an Open Source, PC-based protocol analyzer project that provides network analysis features that can help a developer understand the behavior of a VoIP installation. Wireshark can monitor and collect Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) packets from a network and sort and display them in an intelligible way.

Step 1: Changing the date format

Open the wireshark application
Go to View > Time Display Format
Click "Date and Time of Day" (first option)

Step 2: Setup Network Interfaces

Go to Interfaces > Capture
A new screen will appear which will inform you of the network cards (NIC's) connected to your PC.

Step 3: Configuring Options and starting the application

Click Options
Select "Capture packets in promiscuous mode"

Step 4: Filtering the SIP protocol

Wireshark will now be capturing all data packets on your PC. You will need to simply this by simply entering in "sip" into the filter field as shown below.
Make a test call using a softphone with your engin service to the problem number. We recommend NCH. See KB157
Click Stop when finished " it's the network card image with the x displayed"

Step 5: Saving Results in .pcap format

Go to File > Save As
Save as in .pcap format (first option)
