Additional how to dial. How to dial an extension number. How extensions work

Today, almost every large enterprise organizes correct and coordinated work through the introduction of so-called extension numbers. An extension number is a numeric identifier assigned to a specific line of an enterprise, for example, a specific department. So, you may notice that the telephone number of the company you need to call consists of two parts. The first will mean the main telephone number of the company, while the second (usually indicated in parentheses) will be the same extension number that will connect you with the desired department or person. Not everyone has encountered this or not everyone can do it, so we’ll tell you how to type additional number Right.

Extension number: dialing rules

To begin, dial your main phone number. Usually this is followed by the words of an answering machine, which lists all available extension numbers so that a person can select what he needs and get through. You must listen to the answering machine to the end!

Next, you need to switch the phone (if it is not switched) to tone mode. Tone mode is a dialing mode when you hear beeps of a certain tone (different for different numbers) when you press the phone buttons. Another mode - pulse - is when when typing you hear clicks of a certain length (the larger the number, the longer the clicks). There are two ways to connect the tone mode. First, on the device itself there is a special button (maybe on the back side) “Pulse-Tone”. We need it to be Tone. Second method: after listening to the answering machine, press the asterisk “*” button on the device (among the numbers, usually at the bottom). You will hear a characteristic switching sound, give the phone time to switch.

After switching to tone mode, start entering the extension number on your phone (no need to reset, just dial the number right away). You will hear a beep (tone) for each button press, this will mean that you are doing everything correctly.

Sometimes the PBX fails and you may be connected incorrectly. It's okay, just ask the person you've met to dial the extension number and transfer you to where you need to go. As a rule, company employees are concerned about the reputation of the organization and will treat your situation with understanding.

If you need to call using this scheme, it is better to use regular phone, since dialing an extension number from a mobile phone is not always possible. Plus, the money for the call will be read from the very beginning of the connection with the answering machine.

Currently, almost every enterprise organizes coordinated work by introducing extension numbers. An extension number is a numeric identifier that is assigned to a specific line of an enterprise or its department. It consists of 2 parts: the 1st part is the main phone number, the 2nd is an extension that will connect you with the desired department or person.

What is an extension number?

To understand how to call an extension number, you need to understand what it is. This is a forwarding point in a virtual automatic telephone exchange to which 1 of the external telephone numbers employee (city, mobile, sip or skype account, etc.). The extension number has a four-digit format - from 0001 to 9999, which is limited by the maximum number capacity of forwarding points on the 1st virtual number.

The first 2 digits of the extension number indicate the serial number of the forwarding list, and, as a rule, belong to the 1st department of the company. The second 2 digits are the serial number of the department employee.

What are extension numbers for?

Unified telecommunications space virtual number V cloud PBX erases real physical boundaries and shortens distances. Its capabilities make it possible to build the activities of various commercial and public structures without additional costs for renting premises, office equipment and other expenses.

Modern companies are a room divided by bulkheads into separate sections. These sections house employees who perform their work. Each workplace equipped with a computer and telephone. To contact a specific person, you need to call the company's main number. When the connection occurs, you dial the extension number, after which the required contact is established.

The use of extensions is increasing because they are convenient, fast and easy to use without the need to spend money on additional equipment. Taking into account the obvious fact that all employees have their own cell phones and, many still have home phones, a virtual exchange allows you to transfer a call to any of them. The transfer can be made not only to the phone, but also to Skyp or voicemail.

How to dial an extension number from a mobile phone?

First, you need to study the company's phone number. How to call a megaphone operator - the first part of the number is the main number of the organization, and the second, which is in brackets, is the extension. Dial on mobile phone main number of the organization and call. An answering machine should answer you. Listen to him completely, otherwise, a failure may occur and you will have to dial the number again. At the end of the message, you will hear a list of the main extension numbers and a proposal to dial the required one after a characteristic signal. Dial the extension number and wait for an answer.

Unlike landline phone, mobile phones do not need to be switched to tone mode, they do it automatically.

In some cases, an automatic telephone exchange (PBX) may connect you incorrectly. If this happens, there is no need to disconnect and re-do the dialing operation. You should contact the person who answered and ask him to independently switch you to the department or specialist that is needed. Usually, company employees are loyal to such a situation. If you come across a person who does not want to transfer you, you will have to dial the extension number again.

How to dial an extension number using tone mode?

Most modern wired phones There are special switches labeled “Pulse-Tone”. If you are connected to a modern electronic PBX that supports tone mode, keep this switch in the “Tone” position at all times. If you only need the tone mode when making calls to information centers or similar services, using such a switch is not very convenient. It wears out faster, and some devices generally respond to changes in this position only after the handset is put on and taken off again.

IN cordless phones switching to tone mode is carried out through the menu. It’s just not very convenient to use this method when calling help desks. If your PBX does not support tone mode, temporary switching is carried out as follows: call the help desk in pulse mode, press the “star” button. After that, all further key presses will cause a series of tones. When you hang up, the phone will automatically switch to pulse mode.,

When making calls to extension numbers from mobile phones, there is no need to switch to tone mode. Even if you do not hear, they are still transmitted to the subscriber. If it turns out that there is no response to key presses, find an item in the phone menu that allows you to turn on the transfer DTMF signals, and activate it.

Sometimes it becomes necessary to transfer tones from wired phones, where there is no tone mode at all. This device can be either push-button or disk-based. In this case, set your phone to a mode so that keypress tones are heard directly from the speaker.

At one time, for us there was only a home or business telephone, also known as a landline or landline. Using it we could make local (city), long-distance and international calls. In even more distant times, telephone operators worked at telephone exchanges, and we could easily turn the buzzer handle of our telephone set, hear their answer, name the subscriber we would like to hear, and receive a connection.

Now it has rapidly burst into our lives mobile connection , and with it a huge variety of brands and models of mobile phones.

However the principles of operation of mobile telephones are the same, and this despite their enormous diversity. The only difference remained in the use of separate modes of landline and mobile phones.

Many landline telephones have retained the pulse mode of operation. This is a mode where the phone transmits signals by closing and opening telephone line.

Algorithm of actions:

  1. Switch to tone (tone) mode, i.e. after dialing and the subscriber answers, we must press the * (star) key (button) on the phone, and in some cases the + (plus) key, which means switching to tone mode.
  2. After this, dial an additional, or as they often say, extension number.

In tone mode, the phone makes a call to the subscriber by transmitting a signal at a certain frequency, where each digit is assigned its own frequency.

Telephones with extensions began to appear due to the expansion of the range of services offered by telephone equipment manufacturers. In the office of any enterprise, it is now possible to install a mini-automatic telephone exchange, which will have a main number and several hundred additional ones, which allows not only to provide telephone communications to all employees of the enterprise, but also makes their work more orderly, logical, and ultimately more productive .

Modern mini-PBXs- these are high-tech products that allow, with certain programming and settings, to work without operator participation, in automatic mode conduct dialogues with subscribers, offer them a choice of connecting to one or another additional subscriber.

We have to master and accept for use such additional service communications. To make this simple and understandable, you need to imagine a fairly simple algorithm for the operation of a telephone network where there are additional subscribers. There is only one main subscriber, and additional subscribers are assigned either directly to a specific employee, or, more often, to a specific function.

The most notable example, perhaps, is any large telephone company, such as MTS, Beeline, Megafon, etc. By calling any of these companies, you will hear an answer from an auto operator who will tell you where you called and offer to dial one of the extensions numbers depending on the purpose of your call. In addition, he will offer you to wait for a response from an operator with whom you can talk “live” and who has broader powers than an answering machine.

Knowing the additional “call sign” of a specific employee, all you have to do is ask the operator to connect you with this additional “character”. The same communication systems are installed in our time in all large banks, large public organizations, public utility services, etc.

The mobile phones we use already operate in tone mode, that is, we do not need to switch the device itself to tone mode, but follow the prompt from the operator or answering machine to press one or another number on your telephone. In some cases, you will need to press the star or hash mark. The operator or auto attendant of the subscriber you called will tell you this.

Step by Step Actions

Understanding extension numbers is not difficult at all:

  1. Study the phone number of the organization you are going to call. If it consists of two parts, then the extension number will be indicated at the end of the main number in brackets, or designated as “ext.”
  2. Dial the main phone number and wait for the operator to answer. If a “live” operator answers you, then in a dialogue with him you will ask him to connect to the subscriber you need, giving him additional numbers, or express a request to connect to a specific person, department or department. If the auto operator answers, listen to him to the end and follow the options he suggests. So, for example, it might be prompted: “To connect to the customer service department, press “2”, etc.

Keep in mind that the countdown of the call time, and therefore the payment, for an extension number begins from the moment the operator’s answering machine answers, and not from the moment of connection with the desired subscriber.

If you dialed, say, “large bank”, and in response the answering operator first offers advertising, and then lists a list of extension numbers, then you have to pay for all this traffic.

Mostly specialists telephone communication It is not recommended to call an extension number from a mobile phone. This is primarily due to the irrationality of paying for traffic, when, for example, you listen to advertising from an answering machine, and further actions by recruitment additional number have not yet started, since the answering machine did not “announce” the menu at its disposal. And in addition, the telephone equipment of the subscriber you are calling with the extension number may be outdated and may not work correctly with modern mobile communication devices.

If your device is equipped or equipped online calling program, for example, Skype, then you can call the extension subscriber and special programs for online calls, such as “Tap the dial icon (square with dots) and enter an extension digit” when necessary.

Your question:

How to dial a number from landline to cell phone?

Master's answer:

Currently very widespread cellular. Calling from one mobile phone to another is easy and simple: all numbers have a single, understandable format. But in the case of a call from a landline to a cell phone, certain difficulties arise when dialing the number.

You will need the country code of the person you are calling when making an international call.

We place a piece of paper with a mobile phone number in front of us. Otherwise, by making long pauses in dialing a number, remembering this or that digit, you give the telephone exchange a reason to interpret this as entering a long-distance code. This means that we risk calling the home phone of a subscriber you don’t know in another city.

Remember the main feature of calling with home phone to cell phone: first digits of the number. In this case, instead of “+7” we type “8”. Prefix "+7" - telephone code Russia. City PBX that directs everything phone calls calls made from home numbers are accepted by default as calls made within local subscribers. 8 is a number that indicates the need for long-distance communication. Moreover, when making a call to a mobile number, the number 8 is also used.

We dial eight and wait for the beep. Next, we dial the remaining numbers according to the principle of dialing them on a mobile phone. First, enter the three-digit (928, 903, 918, etc.) operator code (Megafon, Beeline, MTS, etc.) and the remaining seven digits of the subscriber number.

The complete sequential dialing scheme is as follows: 8 (beep) *** (operator code) ******* (direct number).

If you need to call a mobile number that belongs to an operator in another country, proceed as follows. We dial the number “8”, then “10”, indicating the completion international call. We dial the country code of the intended call (we find out the code on official Internet sites or in help desk). According to principle home network dial the operator code and phone number. For example, when calling to Ukraine, we dial the number “8” (beep), “10” (denote long distance call) “380” (Ukrainian code) *** (operator code) ******* (subscriber phone number).

In this article we would like to address the question of how to call from a mobile phone to a home phone. We were inspired to write it by questions on many forums, where users ask to describe the correct process for dialing phone numbers in cases where you need to call from a mobile to your home. Probably many users do not experience difficulties in this process, but there are still subtleties in it, so you should familiarize yourself with the information that we have prepared for you.

How to call correctly from mobile to home?

Mobile and home numbers are very similar in structure and to make a call you should dial in the following sequence:

  1. Code of the country(so for Russia it is 8 or +7).
  2. Operator code for mobile and area code for home.
  3. The user's phone number(V mobile numbers these are the last 7 digits, and at home the number of digits can vary from five to seven).

To dial a landline number from a cell phone, you need to dial a full set of numbers, unlike dialing between two city subscribers, when dialing the country and city codes is abolished in order to make a call.


Before making a call from your mobile phone, you need to make sure you have the required amount of funds for personal account, since such calls are charged much more expensive than within the mobile network.

In Russia, there are differences in home telephone dialing depending on the location of the subscriber.

You can call from the same city where the contact is located without using the international format - just put the number 8 in front of the city identifier. The long-distance format is necessary for subscribers who have traveled outside the region.

Long-distance communication format for mobile and landline numbers

Alexander M. once left the city of Yaroslavl for Moscow on business. And now I urgently needed to contact my mother, and since the elderly person was opposed to modern mobile phones, she only used a home stationary device. As a result, the son, who was already unaccustomed to such “gadgets,” was a little confused in this situation - he had to contact his neighbors (fortunately, they were more technically advanced). But when faced with a problem, Alexander nevertheless decided to find out what the process of dialing a phone is when connecting mobile and home subscribers.

How to dial a home number in international format?

To call from a mobile phone to your home phone while you are outside the country, you must dial in a special order, which is developed in accordance with international standards.

IN Russian Federation Home numbers are dialed as follows:

  • XXX XX XX – when you need to call from home to home (country and city encoding is omitted).
  • 8 (UUU) XXX XX XX – dialed for long-distance mobile and landline connections, where UUU is the “address” of the city.
  • +7 УУУ ХХХ ХХ ХХ – combination of a landline subscriber in international format(+7 – international code of Russia).
