VoIP phones

VoIP phone

VoIP means Voice over Internet Protocol. VoIP phones (or Digital Phones) send voice data in packets over the IP layer. The services they provide are typically the same as the normal phones but the underlying network and the technology are different.

* It might be a dedicated device (like the traditional handset) using IP connection.
* It can also be a normal phone connected to the network through a telephony adapter (TA).
* Else it can be a softphone.

How does VoIP work?

* When you speak at the handset or a mike or a microphone, your voice generates electrical signals inside the gadget. These are analog signals i.e. the voltage level can take up any value within a range.

* The analog signal is converted to a digital signal using an algorithm implemented by the device you are using. It can be a stand-alone VoIP phone or a softphone running on your PC. If you are using an analog phone, you will need a Telephony Adapter (TA) for this purpose. The digitized voice is arranged in packets (i.e. collection of bytes) and sent over the IP network.

* The data is channeled through gateways and servers to the destination. If the called number is on the PSTN, the server opens a connection to the PSTN and routes your call there.

* While going to the PSTN or at the end device of a VoIP connection, the voice is again brought back to its analog form so that it is perceptible to a human ear.

Introduction to VoIP

What is VoIP?

VoIP is the short form of Voice over Internet Protocol. It is also called IP Telephony, Internet telephony or Digital Phone. It utilizes the IP network (Internet or intranets) for telephone conversations. The service it provides is similar as that of normal landline phones but generally offers a cheaper solution. It has some added advantages and as any other service, it faces some challenges too.

How is this useful? VoIP can turn a standard Internet connection into a way to place free phone calls. The practical upshot of this is that by using some of the free VoIP software that is available to make Internet phone calls, you're bypassing the phone company (and its charges) entirely.
