Weird IP on my network company, I need how to know investigate it

Scanning all devices in my network company I found a IP (sometimes is off) with this mac address:

"e0:5a:9f:xx:xx:xx", as I read this belongs to "IEEE Registration Authority".

This device have the TCP port 5060 filtered as a SIP service.

How do I know which device it belongs to? Or what kind of device is it?
