A corded VoIP phone looks like a traditional corded phone, but is designed to connect directly to an ethernet IP network socket rather than a standard phone socket.
A corded VoIP phone can therefore connect directly to a spare ethernet socket at the back of a a router or to an ethernet socket that is provided in an office via a Cat 5 or Cat 6 structured cabling system and a network switch.
Corded VoIP phones often incorporate a second ethernet connection to enable a PC or laptop to share the same ethernet connection at the network switch. This enables a business to avoid the cost of upgrading their internal cabling infrastructure when implementing VoIP.
Most corded VoIP phones are designed to work on the SIP standard for VoIP communications that is used by most providers of hosted VoIP phone services. SIP is also also implemented on most VoIP PBXs.
However, there are some proprietary corded VoIP phones that can connect only to a particular vendor PBX. These enable VoIP PBX vendors to offer features that are not supported by the SIP standard.
Most corded VoIP phones can be powered either by a DC transformer or by power delivered over the network connection. The latter method is usually referred to as POE (ie Power over Ethernet).
POE is the preferred method of delivering power to VoIP phones mainly because it reduces cable clutter at the desk.
