Let me start by saying that it's hard to find a managed 5-port gigabit switch. There just aren't many use cases for one. But it's perfect as a perimeter firewall - 1 port for the WAN, 1 for the LAN firewall, and 2 for the edge servers. It supports VLAN and therefore works quite well with a range of PoE VOIP phones as well. Highly recommended if it suits your use case.
