Custom sound files are stored on the PBX along the path **/storage/usbdisk1/mikopbx/media/custom**. Music on hold files are stored in **/storage/usbdisk1/mikopbx/media/moh**.

## Music on hold <a href="#muzyka_na_uderzhanii" id="muzyka_na_uderzhanii"></a>

If a client gets into a queue during a call or is waiting for redirection, the PBX plays a melody for him. It is possible to download your own tunes for listening while waiting.

You can do this on the "**Music on Hold"** tab as described above.
