VoIP Tutorial
In case you are not familiar with switchboards, imagine your call being routed to an operator before it reaches the person you are calling. That illustrates how a switchboard works. VoIP uses data packets that are sent and received via the internet. Hence, the basic equipment you will need to enable VoIP is a modem because this is the main device that allows you to get an internet access.VoIP products come as trunk or hosted. If you are still wishing to use your old telephone device while utilizing VoIP at the same time, you will need to purchase a gateway from VoIP vendors. The gateway comes in a data packet that looks like a box. You would have to connect this to your conventional telephone or fax machine to enable VoIP. However, if you have an IP enabled system, there is no need to purchase the gateway.
There are four ways by which you can make the calls using the VoIP. These include internet-internet, phone-internet, internet-phone, phone-phone. If you are making a call towards a phone, it can be a regular, non-VoIP phone. Otherwise, the recipient of your call also needs to have a VoIP-enabled device. If you are making a call through a computer, you need to have a head set and a VoIP software program. If you are making an internet-internet call, the computer you are calling to must also have the same software as you have. Examples of this software are Skype, that of Yahoo, MSN, etc.
