How to build your own VOIP system

1.What is VoIP phone service and how does it work?

  • VoIP (Voice over Internet Protocol) is an IP-based voice calling technology that enables voice calls and multimedia conferencing over the Internet via the Internet Protocol (IP). Other informal names include IP telephony, Internet telephony, broadband telephony, and broadband. IP is an abbreviation for Internet Protocol.
  • VoIP can be used for many Internet access devices including VoIP phones, smartphones, and personal computers to make calls and send text messages over cellular networks and Wi-Fi.
  • How it works: VoIP ( voice over IP )works by sending voice data as : packets through a public telephone exchange, using the voice over Internet Protocol (IP). -The telephone system is built from “gateways” that connect to multiple service providers via broadband links, allowing communication between them. In some areas where the Internet does not yet extend to, or where gateways are not temporarily in place, routing can be set up to allow communication services to be routed through the long-distance telephone network by the nearest gateway.

2.How does voice telephony work?

Your phone will be connected to a switch or router in your local area network (LAN).

  • In a local area network, there is a server hosting the VoIP protocol and an IP address. This server provides information about how users connect to other users on the Internet and, in turn, it receives incoming call requests from other VoIP users. This server also provides information about how users connect and make outgoing calls and messages to other VoIP users.Your phone will be connected to a switch or router in your local area network (LAN). Managing VoIP on Your Internal Network In addition to making sure your internet service can handle your VoIP traffic, you also need to make sure your local area network (LAN) can handle it.
  • When you dial a phone number, your IP phone tells your VoIP service provider to call the other party.
  •  IP addresses are then assigned to both parties for use in making the connection. Once connected, the VoIP service provider looks at the Internet Protocol (IP) packets and determines which packets will go to which destination in which direction.
  • The VoIP service will establish the call and exchange packets from your IP phone to your destination.
  • VoIP phones convert these digital signals back to sound that you can hear.

3.Why I should get VoIP phone service

1) Internet Features and Free

  • An important advantage of VoIP is that it is possible to make or receive calls wherever there is Internet access. Even if the phone does not cover remote and isolated areas like the Internet, all standard features are free – be it three-way conferencing, call forwarding with automatic features, automatic redial function and call identification. Of course it’s also possible to access chat software for outbound VoIP calls, which are even cheaper. VoIP providers always allow unlimited outbound and inbound calls, including international calls. For people who make frequent overseas calls, this means incredible cost savings.

2) Flexible call management

  • VoIP services allow your business to hold important meetings from anywhere without losing the opportunity to select important calls. This relieves many companies of the burden they bear when their voicemail system is filled with unanswered messages. Your VoIP phone connection gives you the flexibility to choose how and where you receive your calls. For example, if you can’t take a call in the office, you can take a call on your laptop or cell phone. Notably, VoIP supports unified messaging with integrated email, voicemail, IM and standard calendaring. If you use popular instant messengers, then consider using VoIP (via the voice call feature). In addition, VoIP can be integrated with all Internet-based applications and services – such as shared files, video/audio conferencing and other similar services.

3) Cost-effectiveness

  • Reducing the cost per call is a major consideration for any business when choosing VoIP technology. The technology is typically not regulated by the same tariffs as other systems such as landlines and GSM. As a result, providers pay less for the service than they would for providing a traditional phone system. In addition, traditional phone systems always involve paying interconnection fees. Since these costs are not part of a VoIP system, your business can enjoy lower monthly phone costs.

4) Enhanced Mobility

  • Many small business employees need to travel to take advantage of national business opportunities. When you use VoIP phones in your business, you can break the limitations of traditional landline systems. You have the freedom to move your business office to another location without the hassle of purchasing new phone lines. This is a major advantage for businesses that need to move frequently to take advantage of new business opportunities.

5) Rich API interface and data integration

  • VoIP phones use the Internet to make or receive calls. This allows your business to integrate with other types of communication applications. For example, when a previous customer calls your company to make a new order, the caller will be identified by the phone’s caller ID. Your company can then easily view customer information, such as contact addresses and other important details of previous orders. Customer relationship management becomes better when all this information is displayed on the screen when the customer is online.  

6)Shared across geographies

  • The VoIP phone system can be networked in multiple places, for example, after the system in Beijing and the United States is networked, the extensions in Beijing and the United States call each other for free.

7)Self-contained teleconference

  • Conference calls can be conducted more easily with a VOIP phone system because the system uses a converged data network. Unlike traditional telephone networks that require additional service charges for conference calls, its VoIP network can easily handle multiple callers. You do not need to pay extra for this service. In addition, VoIP services enhance video conferencing. This is a major advantage for companies that need to connect many remote office workers for meetings on a regular basis.

8)Simple operation

  • The IP phone system is easy to configure, or to operate and manage, and can be maintained with a little knowledge of networking. With the development of VoIP communication technology and Internet technology, today’s IP phone has entered the era of fully intelligent devices, hopeiker IP phone, built-in 5G Wi-Fi, built-in Bluetooth, support content sharing, using Android system, and operate smartphone

9)Easy Cabling

  • IP phone system does not need to be wired like a traditional telephone exchange, it is convenient to plug the IP phone directly into the network cable. You can register your softphone on your computer or cell phone, which means you can use the company’s VOIP phone system to make calls even when you are not in the company.
