What is virtual phone number and how it works

What is a virtual number? You may have heard the term 'virtual number' but not understood what it means. This article will help you understand the pros and cons of virtual telephony.

Virtual number: how it works and what you need it for

Why to buy virtual phone number? In essence it is a normal multi-channel phone number. The main difference from a traditional number is that a virtual number is not tied to a physical telephone set or PBX.

How Virtual PBX works

Principle of operation is to transfer data via Internet (also you can work without internet if you set forwarding from virtual number to mobile or landline or FMC service). To start using Virtual PBX, you need to configure settings in your Dashboard. You can use any number of virtual numbers (depending on selected tariff) and connect any number of SIP-accounts to the system.

How virtual number works:

  • Incoming call goes to your provider.
  • The call is forwarded to the virtual station server.
  • Depending on the settings, the PBX forwards the call to the correct device. The sequence may depend on various factors. The call may go to the first free manager or the one who received the least number of calls.

Benefits of virtual phone number

A virtual phone number will always remain with your company when you move to another area or city. It consolidates all of the company's existing numbers into one and distributes the workload to employees, depending on set scenarios. It also provides employees with free in-house calls. You can set voice greetings and menus, listen to call records, view call statistics and much more.

Disadvantages of virtual number

Operation of virtual number requires a stable Internet connection. If there is a loss of Internet, your company will lose your connection. However, this risk can be avoided by setting up automatic call forwarding to mobile phones in case of emergency. Virtual PBX is unprofitable for large companies. It's easier for them to install their own PBX and hire a specialist to maintain it. If you are deciding whether to buy a virtual number or a PBX, we recommend calculating and understanding which is more profitable for your company.

What is VoIP telephony and how to set it up in the office

VoIP telephony is a technology that has revolutionised communications as it has made it possible to transmit voice messages over Internet protocols. Its name stands for: "Voice over Internet Protocol" – "voice over Internet Protocol". In general, VoIP refers to all methods of voice transmission over IP channels, including such non-telephony things as triggering alerts or operating surveillance systems. But now we are going to talk about a specific application of this technology that most of us encounter – IP telephony.

What IP telephony is and why it's needed

IP-telephony is a telephone communication which is not made by ordinary wired communication lines but by data network with help of special protocols designed for this purpose. Active development of this type of communication began in 1999 after appearance of SIP-protocol which turned out to be rather convenient and simple for implementation and use. Due to low call costs, easy setup and high communication quality, IP-telephony is replacing traditional wired telephone networks. IP-telephony makes it possible to make calls not only to devices connected to the network but also to ordinary landline and mobile phones. This is done using special gateways placed all over the world.

When making a call via IP telephony, the voice is converted into a data packet using a special codec. The data is sent via IP networks, i.e. via the Internet, to the recipient, where it is decoded into a voice signal. Unlike usual telephone network, a user with a certain number can be anywhere as long as he/she has Internet and equipment for calls at the place where he/she happened to be. And a laptop or even a smartphone is sufficient as such equipment.

From this comes an important advantage of VoIP. In traditional telephony the cost of communication increases with the distance between the subscribers. In IP telephony, it makes no difference where in the world the addresses between which data packets need to be transferred are located, as long as they are available: log in to the IP telephony server with your login and password and talk for as long as you need, regardless of where you are now. This gives you one more important advantage – long distance and international calls become much cheaper.

Corporate users of IP-telephony like HotTelecom get a number of additional advantages while using it:

  • Reduced communication costs. And inside a company communication often becomes free of charge even in case of distributed office or developed regional structure.
  • Expansion of functional capabilities in comparison with standard telephony. Functions such as transferring calls to another user, including mobile numbers, recording of conversations and conferencing with inclusion of additional participants in the course of a conversation become available.
  • Access to all the functions of the service in any geographical location, which is especially important when it is necessary to organise remote work of the employees.
  • The set of features can be customized to meet the company's specific needs. For example, you can create lists of priority clients to determine whose calls will be answered first. Recordable voice messages are available which can be used as an auto-informer. Rules can also be created to distribute the workload to each employee.
  • Integration with CRM to collect statistics and analyse this data.
