Router with POE or router connected to POE switch

Hi guys,
I need some suggestions for a setup in my company. It will have five handsets connected to a hosted IP box by metal with inter nodes.
What I require is a reliable 4-8 port POE with router OR a router connected to POE switch. Reliability is a main factor it helps me to be better, and it keeps my blood pressure normal.
Any ideas are welcome.
Thanks.
