Managing call recording

Last Updated : Mar 17, 2026 |

About this task

On the Record Control page, you can enable recording to an RTMP server or a connected USB drive. You can also listen to recordings, download and delete separate files, or clear the entire file list to clean up the storage space. The codec creates a separate recording file for each call.

If you enable USB recording, the codec records all active calls until you disable the Start USB Record switch, the recording time expires, or the storage space is full. The administrator configures the recording time limit. You can see the remaining recording time and storage space on the Record Control page.

For FAT32-formatted USB drives, the maximum recording file size is 3.5 GB. When the USB storage is full, the earliest recorded file is automatically deleted so that you can continue recording. If you store USB recordings on an FTP or SFTP server, you must download the file to your local computer before playing the recording.

Caution:

Do not remove the USB drive before disabling the recording or ending a call. If you remove the USB drive first, the codec does not save the recording.

Before you begin

If you want to record your video to a USB drive, ensure that you insert it into a USB slot.
