Help on finding a Voip ip phone?

I’m looking at completely switching to voip from my land line. I’m looking for a Voip ip phone that is cordless. I’m new to this technology, but I think it needs to be SIP compatible and unlocked. I’m not sure if I can simply get a router and have wifi cordless phones, or if I need to purchase an Internet phone adapter to use analog phone base that can support cordless phone. My main concern is highest quality with cordless phones.

Any help in this direction would be appreciated.
