They look like your conventional phone but IP phones don't need any phone jack to conect and are cheaper to call long distance which can alos be used with your laptop to amke calls on the go
IP phones are very cheap to make long distance calls but if we have a mobile phone why should we go for IP phones? Using one phone is cheaper than using two phones at atime.
I have this exact phone i personally don't like the look of it, its worse than a Nokia 3310.However, it has alot of benefits it is much easier to install and configure than a standard phone system.Also the phone number is based on IP not on location.It has loads more great features too.
