Collecting network log

This article contains step-by-step instructions for collecting network log. This logging information will help us to investigate and fix the problem, which you probably faced with.

MiaRec is intended to support a wide range of Voip phones and IP PBX systems. Sometimes it happens that telephone equipment vendor uses non-standard technique or simply has a bug in a software/firmware. And in this case MiaRec records calls incorrectly.

We appreciate your effort in collecting the log information, which will help us to make our product better.

The process of collecting log consits of the following steps:

  1. Start logging
  2. Make test call
  3. Stop logging
  4. Save collected log into the file
  5. Send log file to us by e-mail

Open menu Capture->Interfaces:


You will see network interfaces, which are available on your server. Something like:


You should choose the network interface which is used for call recording. If you have multiple interfaces and don’t know which to choose, wait for a while and see what interface has a network activity (column “Packets”). On above screenshot you can see that Interface “Intel(R) PRO/100 VE Network Connection” has 541 packets sent/received, while other interfaces have zero or much less network activity.

Click “Capture” button. This will start logging. A capturing dialog will be shown to you:


Now the logging is started and you need to make one or more test calls. When you finish a call, click on "Stop" button. This will stop logging process.

Save the collected log information into a file. Choose menu “File->Save”:


Choose a directory where to save the file and it’s filename:


Click “Save” button.

Compress the resulting file with Zip or Rar archivator and send it by e-mail to

Do not send us file, if it is too big (more than 20MB). Instead, we will open for you FTP account on our server and you will upload the file to our FTP server.

Note: Wireshark is a network sniffer. It writes to file all network packets which are sent over your network. The longer you collect log, the bigger file will be produced. Usually a few minutes of log is enough to investigate the problem. So, do not leave the sniffer in running mode for a long time as the size of resulting file may be too large. Anytime you can stop logging and start again to clear the output file.
