What is Voice Over IP ?

Voice over internet protocol (VOIP), also known as IP telephony, is a system and technology community for providing voice communications and multimedia sessions through Internet Protocol (IP) networks, such as the telephone. VoIP is the abbreviation for “Voice over IP” technology and is in vogue when it comes to telephone systems for small businesses.

A VoIP (Voice over Internet Protocol) system gives you everything that a conventional telephone system does but with one key difference: it’s stored in the cloud. And that means you’re paying less on equipment and upkeep. A cloud-based phone system also gives you much more flexibility and not just from your desk phone, but from your computer and smartphone, you can take and handle calls. So you can use all of the office system functions wherever you are. You’ll never miss another important call with VoIP again.

Similar to conventional digital telephony, the measures, and concepts involved in originating VOIP telephone calls include signalling, channel configuration, digitization of analog speech signals, and encoding. The coded information is bundled instead of being distributed over a circuit-switched network, and delivery happens as IP packets over a packet-switched network. They use different media transmission protocols to transport data streams which encode audio and video with audio codecs and video codecs. 

Voice Over IP Protocols

Voice over IP has been introduced in applications such as VOIP phones, smartphone devices, and web-based messaging using proprietary protocols and protocols built on open standards. VOIP protocols include: 

  • Session Initiation Protocol (SIP), a connection management protocol created by the IETF
  • H.323 – This is one of the first VoIP call control and signaling protocols that got widespread implementation. However, with the advent of newer and less complex protocols such as SIP and MGCP and SIP, H.323 deployments have been increasingly confined to transportinging existing long-haul network traffic
  • Media Gateway Control Protocol (MGCP)
  • H.248 – This media gateway control protocol consist of a converged internetwork of modern packet networks and traditional traditional public switched telephone network (PSTN)
  • Real-time Transport Protocol (RTP) is a transport protocol for real-time audiovisual data
  • Real-time Transport Control Protocol (RTCP) is implemented to provide stream statistics and status information
  • Secure Real-time Transport Protocol (SRTP) is an encrypted version of RTP
  • Session Description Protocol (SDP), a syntax for announcenment and session initiation for Websockets transports multi-media communications.
  • Inter-Asterisk eXchange (IAX)
  • Extensible Messaging and Presence Protocol (XMPP), for presence information, instant messaging, and maintenance of contact list.
  • Jingle, used for control of peer-to-peer session in XMPP
  • Skype protocol

How does VoIP work?

Simply put, VoIP is the process of recording an analog audio signal (such as a phone call, an SMS or an e-mail) and converting it into digital data that can be transmitted over the Internet, with the voice at the other end. Voice Over Internet Protocol (VoIP) is a digital technology that makes it possible to make telephone calls over a local network or over the Internet. VoIP is the use of digital technologies that record the voice of the caller, transform it into data (from one to zero) and send it over a data connection to the Internet to a destination address.

At the same time, they work together to facilitate the movement of the caller’s voice and video as well as communication between callers. When you speak into a computer’s microphone, your voice is recognized as a physical sound wave and converted into an electrical signal using hardware called a driver. These are then converted into binary data by so-called voice codecs (encoders and decoders). This binary data is separated by the operating system into small pieces of information known as packets.

VoIP phone connects directly to your broadband connection and works much like a traditional telephone. VoIP, you can dial in as you’ve always done, but your service provider can also dial in – in tones. 

VoIP phones must be routed to a mobile phone or landline, the carrier must process the Internet protocol on the phone connected to the real phone number to fulfill this function. VoIP calls with a telephone service that saves him long-distance charges.

What are the Uses of Voice Over IP in Business?

Business-oriented VOIP systems have developed into centralized messaging platforms that handle all correspondence phone calls, faxes, voice mail, e-mail, online conferences, and more as separate units that can all be distributed by any means and to every mobile phone. Below are specific ways a business can benefit from the use of VOIP.

How does VoIP Phone System Benefits Business?

  • VoIP enables people to make calls with nothing but their Internet connection

Because of the bandwidth flexibility and low cost that VOIP technology can offer, businesses are switching to VOIP systems from conventional copper-wire telecommunications networks to reduce their monthly phone costs. VoIP requires a single network to run both voice and data traffic, which will greatly minimize bandwidth costs. The costs of VOIP extensions are smaller than those for PBX and main modules. VOIP switches, such as personal computers, can operate on commodity hardware. These systems rely on standard interfaces rather than closed architectures. 

  • VOIP devices have simple, functional user interfaces, and users are also able to make quick improvements to the system configuration

Dual-mode phones allow users to maintain their calls as they switch between an external telephone service and an internal wi-fi network, meaning that both a mobile phone and a cell phone no longer need to be transported. Maintenance is smoother because there are fewer tools to supervise.

  • VoIP telephony systems support visual answering machines that allow users of small business telephony systems to define how incoming calls are routed and forwarded to ensure that important calls are not missed.  
  • Use VoIP long-distance calls to make calls remotely, even from your mobile phone 

VoIP telecommunications can be used anywhere in the world; for example, VOIP services in the United States allow you to call from anywhere in North America at no extra charge. You can sign up with BTelecommunication and pay a monthly fee, or you can pay as you go and do it all on the go. This means you don’t have to worry about international calls, roaming charges or other common issues with international calls.

  • You can reduce your company’s travel and training costs by maintaining an easily accessible and scalable telephone system 

With VoIP, you can make free calls to your employees, even if it is a long distance. VOIPs provides access to the Public Switched Telephone Network (PSTN), also known as simple old telephone service.

What equipment do I need for VoIP ?

None, really. VoIP is ideal for business telephony systems for several reasons: it works with traditional or hybrid IP hosting systems, and it uses the Internet as a communication channel instead of the cable previously used in PSTN networks. Line rental is one of the savings you will see with a VoIP telephone system, especially for small businesses. 

If you are using a broadband internet connection, you do not have to pay extra for a normal landline connection just to make a phone call. More importantly, the person calling you doesn’t need any special equipment, just your normal phone. This allows you to add, move or remove stations from the network without having to call your service provider.

How to Set up VoIP for Business

To be precise, VOIP (Voice over Internet Protocol) is a combination of software and hardware that allows you to make and receive calls over the Internet, rather than over a traditional telephone line.

A VOIP phone system is ideal for a home office or a small office set up for business purposes. A VoIP office phone system is internet-based and you can even use your computer or mobile phone to use its services. It is a great solution for businesses, especially those that have set up small offices as businesses.
