Question

What the diffrance between ip phone and voice over ip?

Answer 1

An IP phone uses Voice over IP technologies allowing telephone calls to be made over the internet instead of the ordinary PSTN system. The phones use protocols such as Session Initiation Protocol, Skinny Client Control Protocol or one of various proprietary protocols such as that used by Skype. IP phones can be simple software-based Softphones or purpose-built hardware devices that appear much like an ordinary telephone or cordless phone or an ATA (analog telephony adapter) which allows to reuse ordinary PSTN phones. One of the primary motivations for implementing such a system is the lower calling cost. When calling other IP phones over the internet one only pays for the usually fixed cost internet bandwidth.

Answer 2

They are the same... but different:

VoIP includes All methods of calling over the Internet.

IP-Phones are "hardware" devices that look like regular phones but are designed to "directly" operate plugged into Ethernet network, router, and/or the local IPBX system.

No PC is required when using an IP-Phone.  VoIP firmware/hardware is built-into the IP-Phone.

Answer 3

No difference. It's voice over Internet protocol either way.

Answer 4

They're the same thing....it's like saying

It's like saying I can't boot my PC

when someone else says

I can't boot up my computer.

IP phone would refer to the actual Voice over IP phone.

Whereas voice over IP refers to the technology as a whole.
