The term VoIP stands for Voice over Internet Protocol, and it is a recent technology that allows Internet users to place voice calls over the Internet. This term may also be referred to as telephony, Internet telephony, or IP telephony. With VoIP Internet phone service, you no longer need a phone to make voice calls. When you are logged on to the Internet, you can make use of your connection to call people anywhere in the world. This type of call is also cheaper, especially when you compare it to long distance voice calls. VoIP calls are less expensive because they make use of the network that your Internet connection already uses. Also, there is no need to install extra equipment which helps lower costs. For this reason, calls made between one VoIP user to another are often free or cost a negligible fee. VoIP calls made to regular phones, or to a public switched telephone network (PSTN), cost significantly more, however. VoIP to PSTN CallsThere are two ways VoIP users and PSTN users can converse with each other. One of the methods is known as direct inward dialing, or DID, which directly connects a PSTN user to a VoIP user. DID calling is provided by VoIP providers. The other method for making VoIP calls to PSTNs, or vice versa, is through the use of access numbers. With this type of Internet phone service, PSTN callers input access numbers that correspond to a certain VoIP user’s extension number in order for a call to be successful. Access numbers are usually charged as local calls, making it affordable for the PSTN caller and free for the VoIP user.
