## Example: Call Analysis
Suppose you need to analyze an outgoing call to the number **74952293042**.
1. Select the log file **asterisk/verbose**.
2. Set the phone number **74952293042** as the filter.
3. Set the **limit** to a sufficient value, such as **2000**, to ensure all log entries are included.
4. In the last line of the log selection, find the identifier:
```php
[2023-03-18 16:28:17] VERBOSE[21654][C-0000000f] app_stack.c: Spawn extension (SIP-1676196499-22-outgoing, 74952293042, 13) exited non-zero on 'PJSIP/302-0000001a'
```
5. In this example, the ID = **C-0000000f**.
6. Repeat the log query but use the filter **C-0000000f** this time.
7. You will receive the entire log of the dialplan process.
8. The obtained data can be sent to technical support for further assistance.

## Campuring network packets
This section allows you to perform a detailed analysis of errors in PBX operation.
"Computer network packets" section
#### Capturing Network Packets
You can start capturing network packets passing through the network interface.
1. To start the process, press the **Start** button.
"Start" button
2. Reproduce your issue: make a call or perform an action that causes the error or failure.
3. Press the **Stop and Download** button.
"Stop" button
The network packets will automatically be saved in the archive **MikoPBXLogs\_log-tcpdump-XXXXXXXXXX**. They should also automatically save in your browser's **Downloads** folder.
Logs file
If you cannot find the archive in the **Downloads** folder, you can [connect to the PBX via WinSCP](https://docs.mikopbx.com/mikopbx/english/faq/troubleshooting/connecting-to-a-pbx-using-winscp) and download it from the **/storage/usbdisk1/mikopbx/tmp** directory - the file will be **log-tcpdump-XXXXXXXXXX.zip**.
{% hint style="info" %}
You can use the search function in WinSCP by entering "**log-tcpdump\***" in the file name field and specifying the search directory as **"/storage"**
{% endhint %}
#### **Download All System Logs**
You can download all system logs accumulated on the PBX. To do this, click the **Download All System Logs** button.
"Download all system logs" button
The system logs will automatically be saved in the archive **MikoPBXLogs\_log-sys-XXXXXXXXXX.zip**. The logs should also automatically save in your browser's **Downloads** folder.\
You can also obtain this log archive from the **/storage/usbdisk1/mikopbx/tmp** directory by connecting to the PBX using WinSCP. The file will be **log-sys-XXXXXXXXXX.zip**.
{% hint style="warning" %}
**Be careful**! If there are many calls or heavy network "load" on the PBX, logs can take up a significant amount of disk space.
