Voice Over Internet Protocol.
Let’s you make phone calls on the Internet, bypassing any land-line systems.
No, you can’t make VOIP calls on a mobile phone. Well, actually, you could call someone who uses VOIP, but you can’t use it on a cell phone, since you have to attach to the cellular system to make any call.
VoIP can be a benefit for reducing communication and infrastructure costs. Examples include:
* Routing phone calls over existing data networks to avoid the need for separate voice and data networks.[28]
* Conference calling, IVR, call forwarding, automatic redial, and caller ID features that traditional telecommunication companies (telcos) normally charge extra for are available for free from open source VoIP implementations such as Asterisk.
* Costs are cheaper mainly because of the way internet access is billed compared to regular telephone calls. While regular telephone calls are billed by the minute or second, VoIP calls are billed per megabyte (MB). In other words VoIP calls are billed per amount of information (data) sent over the internet and not according to the time connected. This makes it cheaper because the amount charged for the data transferred in a given period is far less than that charged for the amount of time connected on a regular telephone line.

You can make calls over a VoIP network with a mobile phone by using “dial-around” services offered by different providers. Probably the most valuable application of this capability is to avoid the high cost of making international calls through your mobile service provider. Typically the way it works is you dial an access number that’s local to you and get connected to the VoIP service, then tell it where you want to call. It will route over the internet to the destination and “hop-off” into the local phone network to complete the call. With some services you can also call a user who is directly connected to the internet, such as on a computer that has software to make and receive calls from the internet.
