-kranti-sip-pcap-analyzer helps you understand voice over IP traffic. Many people find network packet files difficult to read because they contain complex data. This tool translates that data into clear summaries. It identifies when a call started, when a person placed a caller on hold, and when the call ended. It uses intelligence models to answer your specific questions about why a call failed or why audio quality dropped. You do not need to be a network engineer to use this software. It handles the difficult work of parsing technical logs so you can focus on the results.
This application runs on standard Windows hardware. Ensure your computer meets these basic requirements before you begin:
- Operating System: Windows 10 or Windows 11.
- Memory: At least 8 gigabytes of RAM.
- Storage: 500 megabytes of free disk space.
- Network: An active internet connection for the intelligence features to function.
- Software: You do not need to install Wireshark or other diagnostic tools for this application to work. It contains all the necessary components to open packet capture files on its own.
- Go to the Releases page.
- Look for the latest version at the top of the list.
- Click the link that ends with .exe to download the installer.
- Save the file to your computer.
- Double-click the file to start the installation process.
- Follow the prompts on the screen to finish the setup.
When you open the application, you see a main menu. Click the button labeled Open Capture File. A window opens where you can browse your computer for your packet capture file. These files usually end with the .pcap or .pcapng file extension. Select the file and click Open.
The main interface shows a list of all calls found in the file. You see a timeline view that highlights every leg of the communication. Each row represents a specific call. Click on any row to see more details. The tool automatically separates successful calls from failed attempts.
The application monitors the SIP signals for hold and resume commands. When a participant puts someone on hold, the timeline highlights the event in yellow. When the participant resumes the call, the tool marks that point in blue. This feature helps you confirm if audio issues occurred while a party was on hold.
This screen includes an input box for questions. You can type queries such as "Why did this call drop?" or "Show me the error codes for this session." Press enter to send your question. The intelligence model reads the network data and provides a plain English response. It explains complex technical errors in simple sentences.
If the application does not open your file, ensure the file is not empty. Some firewall logs create empty packets that contain no meaningful data. Check that the file extension is indeed .pcap or .pcapng.
If you work with very large files, the application takes time to load the data. Ensure you have enough free RAM. Close other programs that use high amounts of memory before you run the analysis. The tool performs best when it has access to at least 4 gigabytes of available memory.
The chat assistant requires a connection to the internet. If your connection is slow or if your firewall blocks outgoing traffic, the assistant might display an error. Check your network settings to ensure the application has permission to send data to the model provider.
When a new version becomes available, the application notifies you on the home screen. Click the update button to download the latest patch. You do not need to uninstall the old version first. The installer replaces the old files with the new ones while keeping your preferences intact.
Your network traffic remains on your local machine. The application only sends the necessary snippets of data to the intelligence service when you ask a specific question. It does not upload your entire database to the cloud. You control what data the model sees by selecting specific calls in the user interface. We recommend that you strip sensitive information from your packet captures if you handle private network data.
- SIP Session Analysis: Converts technical logs into an easy reading format.
- Automated Detection: Finds hold, resume, and hang-up events without manual effort.
- Intelligence Chat: Explains technical errors using simple language.
- Cross-Platform Logic: Decodes different types of network captures regardless of the source.
- Lightweight Desktop Client: Installs quickly without heavy dependencies or system bloat.
- Visual Call Flow: Displays communication paths between different network devices.
This application uses the Microsoft Agent Framework to coordinate the flow of network data. It parses the PCAP structure and maps the SIP headers to the intelligent agent. This setup allows the tool to maintain context across multiple packets, which is essential for understanding a full conversation. You receive professional insights without needing to understand the underlying transport protocols. The software automates the repetitive parts of packet analysis so you save time on every ticket you investigate.
