Telephone communication is a necessary form of communication for any office. Thanks to modern technologies, today it is not difficult to provide a company with a reliable communication service. A profitable solution is to connect to a virtual PBX. A minimum of equipment and inexpensive tariffs are the advantages of a virtual PBX. Let's talk about the functions and capabilities of this tool in detail.

How cloud PBX works: everything ingenious is simple

A virtual, or cloud, PBX (autonomous telephone exchange) is an economical and effective solution that provides new opportunities for organizing office communications. Its fundamental difference from analog telephony is that no wires are used to route subscribers - communication is established via the Internet. The station itself is located on the provider's server, but the user has access to control.

One of the strengths of cloud PBX is multichannel numbers with the ability to forward a call to any number of the company's subscriber. The main advantage of multichannel numbers is the ability to receive a large number of calls at the same time. In a highly competitive business environment, it is not permissible to force customers to listen to short beeps on the phone. Today, those who value their customers answer the call the first time, thereby gaining trust and increasing the profitability of the business. In addition, thanks to the multichannel number, you can receive a call not only using a landline or mobile phone, but also using a tablet or smartphone. For this, developed free apps for four major operating systems (Android, MacOS, Windows, iOS). At the same time, all the advantages of the internal network are preserved - the ability to assign extension numbers to the combined phones for quick communication employees among themselves.

Another possibility of a cloud PBX is voice menu, or, as it is called in everyday life, "electronic secretary". It is this that helps to connect the client with the right employee, which allows you to partially relieve the telephone line.

The indisputable advantage of a virtual PBX is also the ability to perform video calls, which cannot be done using analogue stations. Video conferencing, negotiations and meetings are a productive form of cooperation that allows you to avoid business trips, renting premises and many other costly organizational issues: saving time and money is obvious.

Another cloud PBX know-how is virtual fax... It is received automatically - the fax arrives at email, it remains only to print it on a printer.

Another function is available, which is also sometimes necessary, is blocking unwanted calls, or the so-called black list.

In addition to the above possibilities, the multichannel number allows you to configure site integration... This means that the client will be able to call your company directly from the website by simply clicking on the appropriate button or by clicking on the image with your phone number.

The service will allow you to communicate with a group at the same time conference calls... Now meetings and negotiations can be conducted remotely. Agree, this is relevant when employees of one company are in different cities and even countries, or simply do not have the opportunity to appear in the office on the appointed day and hour.

Another important advantage of a multichannel number is the ability to connect to the service reporting- this will allow you to keep your finger on the pulse of events, control the effectiveness of telephone conversations.

If we talk about restrictions, then there is only one thing: the need for a stable data transfer rate. For the successful operation of a virtual PBX, the value should not be lower than 512 Kbps in both directions.

Cloud PBX advantages: faster, cheaper, easier

Comparing analog and virtual PBX, it is easy to be convinced of the indisputable advantages of the latter. First of all, there is a tremendous saving in time and material costs. There is an opportunity to reduce the staff. This is especially important for young companies that are just starting their way in the business world: they do not need to buy a lot of telephones, pull wires, organize too large a call center. Also, virtual PBXs greatly facilitate the work of firms that have branches in different regions of the country or partners abroad.

To install a cloud PBX, you just need to register on the provider's website and select the necessary functions in your personal account. At the same time, tariffs for such a connection are more than affordable. With the transition to new technologies, costs are reduced by 70-80%.

According to the research company J’son & Partners, the number of virtual PBX users in Russia by the end of 2014 was about 72 thousand clients. Over the next year, the number of connections doubled.

Virtual PBXs are especially popular among small and medium business owners. Also, such an offer can optimize the work of online stores, because their contact with customers largely depends on the level of reliability and quality of telephony. Cloud PBX will be an excellent solution to communication problems for companies operating in the field of tourism, hotel and restaurant business, since using this tool you can quickly regulate the number of telephone lines, which is very important during the increased volume of seasonal work.

Cloud PBX increases the mobility of employees, because it can be used to unite even branches that are far from each other. And such a characteristic as scalability will allow you to develop rapidly without thinking about purchasing new expensive equipment.

Which cloud PBX should you choose?

If you are interested in purchasing a virtual PBX, then it is important to choose it correctly. This is not an easy task, since there are quite a few interesting offers on the market. Let's define what criteria should be used to choose a PBX.

First of all, it is the reliability of the communication provider. Do not be lazy to find out how long the company has been providing such services and who is on the list of its clients. Also, it will not be superfluous to read user reviews on independent portals.

Before concluding a contract, make sure that the provider offers high-quality communication - without delays and noise, and its services are presented in a wide range: from technical support to maintaining the confidentiality of transmitted information. The variety of tariffs is also a plus, since it allows you to choose the conditions you need.

A convenient interface for managing a cloud PBX and many settings are also considered an advantage, since they allow you to easily select the parameters you need.

A virtual PBX, among other things, helps to evaluate the effectiveness of advertising campaigns and the activities of call centers: it shows the total number of incoming calls, identifies the hours of the highest and lowest load, determines the ratio of the number of received and lost calls, etc.

Each virtual PBX service provider has its own basic packages... Typically, the standard tariff includes: direct city number, voice mail, blacklist, a certain number of internal numbers, voice menu, call forwarding and detailing. Small businesses can limit themselves to such an offer.

For larger organizations working in the field of HoReCa or trade, the call-center service may be of interest, and for organizations that constantly communicate with consumers (banks, trading companies, call-centers and technical support services), the purchase will be useful " toll free numbers"8-800 and 8-804.

Today in Russia there are more than 60 providers providing virtual PBX services. At the end of 2015, seven operators were among the most successful and in-demand. This is MMT with its virtual PBX - YouMagic.Pro, Telfin, Megafon, Mango Telecom, Zadarma, UISCOM and Rostelecom. As for the advantages of technical and consulting support, the leaders here are three companies: MTT, Telfin and Mango Telecom.

A virtual PBX is not a fashion trend. This is a really productive scheme for receiving and transmitting calls without the use of outdated wired telephones. Availability, mobility, scalability, ease of management - all this makes this solution a truly profitable option for both small and medium-sized and large businesses.

Usually, to coordinate the work of employees and communicate with customers, companies use a familiar communication tool - a telephone. However, having a large staff of employees and the need to make / receive a large number of calls every day, one device for the entire office is clearly not enough. In this case, the need arises to introduce more serious and modern communication equipment.

It is possible to ensure the maintenance of uninterrupted communication by installing an automatic telephone exchange and distributing telephone lines to workstations. However, this method has its drawbacks - a significant increase in communication costs, certain organizational difficulties, a technically limited resource. A simpler, more practical and economical way out of the situation is to contact a VOIP telephony provider and organize a cloud PBX in the office. In order to appreciate the benefits of such a communication solution, you should know how a virtual PBX works and what opportunities it provides.

What is Cloud PBX?

If we talk about the functions of the PBX in general, the station is the company's telephone system, through which the internal numbers of the organization are connected to external telephone lines and mobile networks... In the case of an analog PBX, the "hardware" is actually at the client's disposal and is a complex system of devices.

A virtual PBX is not any machine or device. It is a service provided by IP telephony operators that replaces a physical office telephone exchange. In this case, technical equipment is used and software provider, and the client receives a software IP-PBX for use, the connection to which is via the Internet. The use of IP-PBX is possible via VoIP phones or software applications IP telephony. This solution allows you to quickly and without significant financial costs to install telephones in the office and provide each employee with a personal work phone.

How does cloud PBX work?

As for the principle of operation of a cloud PBX, VoIP technology is the foundation of IP telephony - it is this technology that determines the procedure for transmitting audio data on the Internet. Direct transmission of information occurs using Internet or Internet protocols. For commercial purposes, the signaling protocol SIP is usually used. All data is stored on the servers of the provider providing the service. In this case, the functionality of the PBX can be customized by the consumer for the needs of a particular business.

The server providing the operation of the virtual PBX is engaged in the algorithmic distribution of incoming calls to personal computers, smartphones, laptops, etc. The number of means of communication for distribution is practically unlimited. Initially, absolutely all calls are made to a single company number, which is registered on the server. When a call comes in, the complex system algorithm used by the virtual PBX directs the call to the desired address.

In other words, the mechanism of operation of a virtual PBX is as follows: all incoming (simultaneously or at different times) calls arrive to the virtual "cloud", after which the call is instantly redirected by the server, according to the scenario set by the administrator, to the recipient's SIP phone or a group of employees. In addition to connecting a call to a physical number, the following incoming call processing logic can be configured:

• Play a greeting, sound file or activation of the voice menu;
• Call forwarding depending on the time or day of the week;
• Execution of an action in the event that all channels are busy or there is no answer;
• Accepting a message to voicemail and sending it to e-mail.

Benefits of using a virtual PBX

Due to the peculiarities of the service, there is no need to lay wires, purchase expensive equipment and its further maintenance to connect telephony. It is enough to have a stable and preferably high-speed network connection. Thus, with minimal one-time costs, the company gets all the capabilities of an office PBX, and regular costs of the communication link are minimized.

In addition to the high quality of telephone communications and multichannel numbers, modern offices also need additional functions for effective work, which can also be enabled within the framework of a cloud PBX. This includes:

• The ability to integrate with the site;
• Detailed reporting;
• Recording telephone conversations;
• Video calls, voice mail and conference calls;
• Electronic fax;

As practice shows, the use of a virtual PBX can significantly simplify business processes and optimize costs, and also provides unlimited opportunities in terms of expanding the number of employees. It is equally important that due to the lack of physical binding, the office can change its location, and employees go on business trips, but this will not affect the operation of the virtual PBX and the uninterrupted communication.

The operation of a large and multifunctional enterprise is impossible without the most necessary means of communication - the telephone. Of course, if your company is constantly expanding, and there are more and more consumers, one telephone set it will be quite difficult to get by. Another necessity is that the entire network of the enterprise has a number that is the same for everyone.

This means that your office, company or enterprise should be connected by a multi-channel connection, which should be united by a simple and beautiful number. But how to choose the right multichannel network without compromising your own wallet and company income? In this case, a new, incredibly convenient way of communication will come to your aid - voip-telephony (it is also called sip, the Internet, or ip - telephony). Voip telephony is a communication that is rapidly gaining momentum in the field of business and entrepreneurial activity.

The principle of operation of a virtual PBX and IP telephony

The principle of its operation is quite simple - a telephone exchange located on the server of your chosen provider is configured for the functionality of your enterprise. Data transmission is carried out using SIP and VoIP protocols. They are required for the transmission of multimedia and voice messages. The data is stored on the so-called cloud PBX of the provider that provides you with services.

Virtual PBX services are now represented by both IP telephony providers and mobile operators and Internet providers. Physically, the PBX is hosted by the provider, and the company gets access to it via the Internet. The Internet is also used for making calls, transferring data, etc.

The rapid growth in the popularity of IP-telephony was caused by significant shortcomings of traditional telephony, especially the low quality of communication and its high price, because it is a fully wired technology. Introduced in 1995, IP telephony has taken over the world in two years, allowing users to make cheap calls with sufficient security and quality.

Traditional dialing, voice communication, data transmission and video calls in IP telephony are carried out via the Internet, and the central element of this system is Gateway... This is a device that is connected to both telephone lines and the Internet (or another IP network). Information is transmitted through communication channels encrypted to reduce the load on the network, otherwise it would require too high throughput... The gateways are equipped with speech encoders that encrypt it at the input and decode it at the output. In this case, the time for digitizing, depending on the flow rate, is from 0.75 to 10 ms. A small and constant delay in the flow of speech information is always present, but for a person, a delay of up to 250 ms is almost invisible.

Thus, unlike traditional telephony, where data is transmitted through a dedicated connection over telephone lines, in IP telephony, data packets go over a common network with a specific address... Through the Internet, the company also gets access to its virtual PBX, setting it up according to its needs. Hence and numerous advantages of a virtual PBX andIP telephony.

Why is sip telephony so good?

First, it is very convenient. You will be able to control the work of the company, even when you are hundreds of kilometers from your enterprise! Competently organized work of employees, and constant control are the main components of the company's success, and with sip-telephony your employees will work clearly and harmoniously. For example, using conference calls, you can conduct group meetings or negotiations, even while in another country. Another advantage of IP telephony is its endless possibilities. To connect to an IP telephony provider, you only need to have an Internet connection, and you can make calls from anywhere in the world. This greatly expands the possibilities modern companies... For example, call-center employees can work anywhere, only the availability of the Internet is important, which is not a problem today.

With a multichannel number you will be able to receive an unlimited number of calls, which means that in the very near future your company will be successful, because the key to successful work is constant communication with consumers. Among the advantages, it is also worth adding the ability to forward calls, determine and repeat the number, which in IP telephony are provided free of charge, while ordinary telecommunications companies will require an additional fee for this. In addition, video calls, messaging and file exchange during a call, viewing information about whether a subscriber is available, and managing the address book become available. The busy line problem is solved by call forwarding or switching to standby mode and it's all highly customizable.

well and main advantage Internet telephony is an affordable price. The costs of paying for a virtual PBX are minimal, regardless of the cost level or the size of the enterprise. This is due to the technology of data compression and the use of the entire capacity of the telephone line, the absence of connection costs, because Internet access is practically everywhere. Internal calls within the company become free, and long-distance and international communication- 70-80% cheaper.

You don't need wires or expensive equipment to use sip telephony. Setting up a virtual PBX from scratch takes 5-30 minutes and does not require any special knowledge. For comparison: connecting an enterprise to a traditional PBX will take from one day to two weeks. Using a multi-channel PBX, you can be sure that your company will always be on top!

You can save time not only on setup, but also on support. A traditional PBX requires the involvement of specialists from third-party companies or the presence of a professional on the staff of the company, who would also be involved in maintaining the system. In the case of a virtual PBX, all required settings as you work, you can do it through the web interface.

Using a virtual PBX make the company mobile... You can easily change the location of the office and immediately start working in the new location. When using a traditional PBX, more time is lost on transporting all equipment, setting it up and finding a service provider.

A virtual PBX allows a company to get started quickly, and its employees can be located in different locations. A direct city number will inspire the confidence of customers, and the company itself can do without even a real office, because the location of the virtual PBX is unknown to the caller.

Together with the low cost of communication, the indisputable advantage of IP-telephony is also connection quality which is constantly improving. This is achieved by improving work algorithms that solve some problems of IP networks, incl. and delays. A private network also allows you to independently make settings and change the number of subscribers on one line, bandwidth and other parameters, improving the quality of communication. IP telephony is developing rapidly, and every year users are offered new and more advanced technologies and protocols that improve the quality of communication.

Reports on the number and duration of calls, the "black list" function, recording of telephone conversations, which is important when working in the field of sales and service provision, are other advantages of the technology.

Are there any downsides?

Like any technology, IP telephony has its drawbacks. They are more than overlap with merits, but for the objectivity of decision-making, they must be known in advance. Among the main disadvantages of IP telephony with access to a virtual PBX is the fact that all data companies about calls and recordings of conversations are with the provider... If there are conversations on the phone with the mention of trade secrets or other classified data of the company, then they can fall into the hands of intruders, although it is not so easy.

Along with the simplicity of managing a virtual PBX, you will have to accept it. limited functionality... The PBX can be more finely tuned, but this will require qualified specialists, which has already been mentioned. Virtual telephone exchanges about great for small and medium-sized businesses... They can also be used by large companies, but PBXs will be preferable for them.

Since IP telephony uses the Internet, with a slow connection or a heavy load on the network, connection breaks are possible, but such problems are gradually disappearing thanks to improving technologies. Fans of traditional telephony and PBXs will be able to find fault with a few more little things, but it's hard to argue with statistics that record the rapid growth in popularityIP telephony and virtual PBXs, explained by the superiority of advantages over disadvantages.

How a virtual PBX works we can consider the example of the work of any server on the Internet.

A server is a computer that has a permanent ip address and Domain name so that any user can get access to information or computing power of the server at the address.

Virtual PBX this is a server installed on the Internet with an ip address, we enter this address, password, login on our phone and get access to the telephone station through which we can make phone calls to any number by dialing it on our phone.

Myself how a virtual PBX works significantly differs from the principle of operation of most telephone exchanges. Any other automatic telephone exchange has a case in which various electronic equipment is enclosed; this is a kind of special computer. To connect a phone, it must be connected with a cable or via the Internet to a physical device - a telephone exchange.

A virtual PBX does not have a physical shell, its location is not defined, the subscriber has only an IP address or domain name. When typing, a dialog box will appear in which you must enter your data: password, login, communication method or interaction protocol. At first glance, this type of communication may seem unreliable, but I assure you it is completely wrong! What protocols and channels ensure the quality of telephony and reliability of communication: dedicated optical cable, TLS, daily limit of telephone calls, Deep packet inspection.

Service connection - telephone communication takes place within one working day, or rather from 5 minutes to 24 hours, depending on the complexity and technical assignment. Such connection speed allows the company when moving not to waste time on installing and setting up telephony, but almost immediately to provide the entire office telephone connection.

- the transmission of telephone traffic via the Internet is carried out by various routes, it is impossible to calculate the possibility of a particular conversation and the route.

Deep packet inspection analyzes packets and if a password is brute-force from one ip address, such an address is blocked

Each user of a virtual PBX can be conducted (if he wishes) as a user with one ip address, respectively, all other ip addresses cannot enter as this user

There are several concepts that sometimes mislead the subscriber and he cannot understand what is what and what he needs to pay for.

When connecting telephony using a virtual PBX, the subscriber can have several phones that can be connected in different ways... Although, if the subscriber wishes, all phones can be connected only in the office using one multi-port gateway: 2 lines, 8 lines, 32 lines. The number of lines is the number of sip ports.

Some subscribers create their telephone network in more complex form, this kind telephone network allows you to use a virtual PBX. All phones in the head office are connected to a multi-port gateway, while an optical cable is laid between the provider and the subscriber, which allows the office to be provided with highly reliable telephone communication. Remote employees connect to the virtual PBX via the Internet using ip phones and mobile phones With installed program zoiper. The total number of lines is considered internal, all internal lines are equipped with short numbers: 101 ... 199 and 901 ... 999, how easy it is to calculate, 900 internal lines are obtained with the maximum possible number of subscribers. The number of external lines will be determined separately. All internal calls (between subscribers are not charged - free of charge), all external ones have the price of one minute of conversation. The number of outside lines is determined separately for prudence and security purposes.

Virtual PBX, virtual number

Review of sites in terms of usability

The website of the service pleased us with both the design and the text content. The information is presented clearly, beautifully, neatly. Does the site make you want to order the company's service? Yes, it does. There is no intrusive callback window or online consultant, competitive advantages are well described, leading clients and awards are listed. No flaws were found.

The MTT website interface has its pros and cons. We liked it for its informativeness. All information is divided into intuitive sections. The descriptions are also easy to follow. The service lacks beauty, aesthetics. There are no selling elements in it.

I liked the informativeness of the site very much. On the home page you can read a lot about the company, including the benefits of the service, a description of the opportunities and tariffs. In addition, you can watch a video presenting the site's services. The only thing is that the site is not very convenient for viewing. It seemed to us that the designers could do their job better, but still very well.

The advantages of the site are its simplicity and ease. This is the impression he leaves behind. It's really nice to use it. The information is covered in sufficient volume. Here you can read not only basic information, but also about the benefits of using the service and reviews from satisfied customers. The only moment that distracted was the frequent offer to contact an online consultant during a long stay on the site. It is good that an online consultant is present, but the question is how tactfully it is configured.

When you see Oktell's website, you will immediately want to sign an agreement with them. Then, perhaps, you will change your mind, but after all, the first impression is not going anywhere. This scale will fascinate you. As befits a major market player, the site is designed in muted official colors. On the site you will find everything about service opportunities, company success stories, as well as a “strong” list of clients. You will not find only one thing - information about tariffs.

I liked Stream Telecom for its informativeness. It was made with high quality, with love. This can be seen in small details, a careful description of the benefits. The visual component and the content are on the same high level... An online consultant is provided for communication, which responds very cheerfully to the desire to contact.

It seems that there is nothing to complain about, and we will not do this, but there is a feeling, “somewhere we have seen this”. There is a lack of a sense of uniqueness. However, the site is convenient, informative, ergonomic. The shortcomings in it, if you scrape together, then they are all so insignificant that their name is subjectivity and fleetingness.

Number of rooms at the most expensive rate	Unlimited number of channel numbers	Three rooms (plus the ability to connect others for an additional fee)	Sixty-four communication channels	One multichannel number	Up to ten thousand multichannel numbers	Twelve multichannel numbers	One multichannel number

As you can see from the table, the lowest rates are offered by Mango-Office and Uis services. If you need a functional, inexpensive service - welcome to the hospitable Mango-Office and Uis networks.

At first glance, the tariffs in the service seem to be the most affordable, but it should be mentioned that the "call recording" option is paid separately - 590 rubles per month. Taking these costs into account, it goes into the “market average” category. However, if you do not need a recording of employee conversations, then the offer will be very beneficial for you.

We decided not to disclose our tariffs. They are announced only when a commercial offer is formed.

Offers unreasonable prices for both virtual telephony... This is due to the fact that the specificity of their services is somewhat different from the one we are considering.

And they offer average rates for the market. It is worth noting that their prices are not too different from those offered by the most profitable services.
