VoIP is Voice over Internet Protocol and is also called IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband. It is the routing of voice conversations over the Internet or through any other IP-based network. VoIP, or Voice over Internet Protocol, is a method for taking analog audio signals, like the kind you hear when you talk on the phone, and turning them into digital data that can be transmitted over the Internet. Voice over IP protocols carry telephony signals as digital audio, typically reduced in data rate using speech data compression techniques, encapsulated in a data packet stream over IP.

VoIP facilitates tasks that may be more difficult to achieve using traditional networks. The voice over internet protocol provides an ability to transmit more than one telephone call down the same broadband-connected telephone line. This makes VoIP a simple way to add an extra telephone line to a home or office. VoIP can be secured with existing off-the-shelf protocols such as Secure Real-time Transport Protocol. It is necessary to encrypt and authenticate the existing data stream only.

VoIP is location independent, and it only needs an internet connection to get a connection to a VoIP provider. VoIP phones can work from anywhere with a sufficiently fast and stable Internet connection. VoIP phones can integrate with other services available over the Internet, including video conversation, message or data file exchange in parallel with the conversation, audio conferencing, managing address books and passing information about whether others are available online to interested parties. The VoIP user may use a VoIP Pulse to Tone Converter, if needed. Fixed delays cannot be controlled but some delays can be minimized by marking voice packets as being delay-sensitive.

Suraj informatics is a major provider of VoIP. The company provides VoIP implementations to face problems dealing with latency and jitter. Variation in delay is called jitter. The effects of jitter can be mitigated by storing voice packets in a buffer upon arrival which then avoids a condition known as buffer underrun. The company’s VoIP provides a secure, reliable, jitter proof, and high bandwidth system. VoIP can turn a standard Internet connection into a way to place free phone calls.
