How to do Skype Telegram do-it-yourself radiotelephone extension cord. Everyone who is connected with computers knows very well Skype. Working on Skype allows you to negotiate almost free of charge and see the interlocutor who is on the other side of the world. Skype is also very convenient for local calls, when you need to hold lengthy discussions or consultations. In ordinary life, additional communication equipment other than a microphone, speakers or headset is not required. It is convenient to work with such a communication set when negotiations are not long or you constantly need to access a computer. And when conducting lengthy negotiations on abstract topics, constant connection to a computer can tire and hamper freedom. To eliminate this inconvenience, to plug radiotelephone to a computer. Studying the documentation for different types radiotelephones showed that there should be no difficulties in connecting to a computer. We managed to pick up a phone of the initial DECT series from telephone trash Panasonic KX-TCD700 phones are reliable and can still be found in offices. This is a 900 MHz radiotelephone with a communication range of up to 70 meters and, most importantly, requires “AA” batteries for its power, and not special batteries. With the choice of a donor radiotelephone, the question of how to make a wireless extender for Skype with your own hands began to be resolved.
How to make skypophone with your own hands
1. We insert the batteries into the handset, connect the 220v adapter to the base and check the operation of the radiotelephone when connected to a regular telephone network. The device must be working. The subtleties of setting the base tube are given in the instruction manual.
Phone is a donor
2. We open the base. At first it was uncomfortable at the sight of a dense installation. But the study of the circuit and the abundant marking of the elements on the board made it possible to calculate and find the connection points to the conversational node of the board. Connection points can be chosen as guidelines when adapting to a computer and other phone models, in my opinion, any radiotelephone will be able to connect. It was necessary to find the transmit and receive signals - going to the conversational node of the telephone line and take them to connect to the microphone input and line output of the computer. According to the scheme, these are the signals RX-AF and TX-AF, respectively. To connect to a computer, a test point TP82 and a capacitor C62 are selected (test point TP96 is not marked on the board).
The insides of the base Fragment of the circuit Fragment of the wiring diagram3. The connection cable is taken from the cheapest computer headset, it has pleasantly accelerated the work. The ends of the cable conductors are cleaned and covered with solder.
4. To isolate galvanic connections along signal circuits and limit the strength of signals, connection to control points was made through two RC circuits. An RC circuit is a series connection of a 0.1uF capacitor and a 5.1kΩ resistor. Soldering points are shown in the wiring diagram and photograph. To checkpoints soldered extension wires. The capacitors are glued with hot glue, and the resistors are fixed in a volumetric way.
Computer headset We connect to the board Parts are filled with hot melt adhesive
5. The headset cable is passed through the hole in the RG-45 connector and soldered with the corresponding ends to the capacitors. the cable is fixed in the connector with hot glue. The RX signal goes to the microphone input, the TX signal goes to the line output. Passing the cable through the connector performed at the same time foolproofing. I admit that when the phone is connected to the telephone network at the same time, some troubles may occur, for example, with a microphone input.
6. We assemble the base and connect the radiotelephone. The self-made radio extender based on the Panasonic KX-TCD700 phone started working right away, it was only necessary to correctly adjust the signal strength using computer settings. Tests have shown the performance of the device at a distance of 30 meters from the base (there was a comfortable sofa 😉). Since it is not possible to establish a connection in the program from a phone connected to the computer, the connection is established in the usual way, and then you can pick up the handset by pressing the key and start talking.
Cord exitIt follows from the features of the connection that the speech signal became more compressed (peculiarities of the radiotelephone), but at the other end the interlocutors usually did not notice anything unusual, except for an incomprehensible empty space in front of the computer when the video link was on. At the end of the conversation, it's a good idea to return to the computer and check the connection is broken.
From further improvement homemade device you can consider the option of end-to-end control of speakers or a computer headset, which will turn off when removing the handset from the base or turning it on, but this will certainly complicate the design.
At the request of readers, connection points for Panasonic phones KX-tcd410rum (rus) / KX-tcd412rum (rus) / kx-a141rum (rus) / kx-a142rum (rus) and , KX-TC1245RUB ( , ) were drawn. Friends, do not forget to report the results of the alteration, the site is working for thanks.
Scheme KX-tcd410 Arrangement of elementsPanasonic is known worldwide for its reliable and durable telephone and fax products. Therefore, it is not surprising that many are concerned about the question: “how to set up a Panasonic radiotelephone?”.
Therefore, we will try to briefly outline the most important functions needed for a conversation.
Connecting a Panasonic radiotelephone
There is a huge variety of telephone equipment from this company on sale, but all of it can be divided into some categories that differ in the number of handsets, additional features and others. But in any case, all radiotelephones have the same principle of operation, therefore, they are connected in the same way. Therefore, below we will talk about how to connect a Panasonic radiotelephone. The first step is to remove the device from the package and place it in the desired location. In this case, the kit will contain:- adapter for connecting power to the base;
- telephone cord with RJ plugs;
- a tube;
- a set of AAA Ni-MH batteries.
Base connection
The first step is to connect the adapter to the network and to the base. For the first start, the power switch is switched to the On position on both devices. To search for a handset, the call button with the corresponding icon is pressed. On Panasonic devices, it is located on the front panel of the base.Setting up a Panasonic radio
Now let's figure out how to set up a Panasonic radiotelephone. The principle of setting up phones from this brand is the same and is performed using a push-button dial in accordance with the instructions. You can download it on the official website of the company itself.For the first start after physical connection telephone set you need to register the handset. To do this, follow these steps:
- On the handset, after turning it on, press the "Menu" button.
- Use the arrows to select Handset Settings and press OK.
- Next, you need to select the "Handset Registration" menu and click "OK".
- On the base unit, you must press the handset call button. It has a corresponding pattern and, as a rule, is located in the most prominent place. It can also be used when the handset was lost to search for it. Only in this case, you do not need to hold the button. To register the handset, press and hold the button for 5 seconds.
At this time, the inscription “Base PIN” will appear on the handset. Accordingly, we introduce it. The default is "0000" and confirm the entry by pressing the "OK" button. After successful tuning, the antenna indicator on the handset stops flashing and becomes permanently lit.
If for some reason the registration of the handset did not occur, then it is necessary to remove the previously attached handset and repeat the process again.
For this you need:
- press the "OK" button;
- go to the database settings and confirm the choice "OK";
- in the current window, the code “335” is entered and when you press the “OK” button, you will be taken to the menu for selecting registered handsets. Use the arrows to select the one you need and click "Yes".
When changing the PIN-code, be sure to save it on a physical medium, otherwise you will have to contact a specialized service.Customizing phone settings
After the initial launch and registration of the handset, the phone must be configured for comfortable operation. These settings consist in choosing the menu language, setting the date and time. You can also select the dialing mode if necessary. From the manufacturer's factory, a pulse mode is set, which corresponds to modern telephone lines.Menu language selection
Setting the date and time
To select a language, go by pressing the "OK" button in the menu and find the sub-item "Menu Language". We confirm the choice with the "OK" button and get into the list of all supported languages. In it, using the up and down arrows, we find the required one and again press the menu selection button. On some phones, you must press the end call button to confirm the action and exit the menu.
MICROPHONE required
If the computer has sound card and speakers (headphones) are connected, then this is the easiest way.
The cost of simple microphones is 50-100 rubles.
They are often made with a flexible leg and on a stand.
- If you listen through the speakers, then there is no privacy of the conversation.
2 way
HEADSET required
If the computer has a sound card, then you can connect headphones and a microphone made in the same design to it (the so-called "headset").
The cost of headsets is from 300 rubles and more.
The headset must be connected with one plug to the microphone jack, the other to the headphone output on the sound card.
The connected microphone can be used to record podcasts.
+ Both hands are free.
- When talking for a long time, if the headset is heavy, you may feel discomfort.
3 way
Homemade ADAPTER
for a regular (or radio) phone working as a headset
If the computer has a sound card, then you can connect a home-made adapter to it, to which it connects regular phone or a radiotelephone as a headset.
The cost of a landline phone is from 350 rubles and more (you can use the old one with a round dialer). However, today an old unused phone is not a problem to find.
The cost of parts for the adapter is less than 50 rubles, not counting the power supply for 9-12 volts.
The adapter must be connected with one plug to the microphone jack, the other to the headphone output on the sound card (not to be confused with speaker output!).
The telephone conversation takes place in the usual "style".
+ No one will hear the content of the conversation (relatives, neighbors).
- Source needed direct current at 9-12 volts. Since the current consumed is about 20 mA, the Krona battery will not last for a long time (10-15 hours). Larger capacity batteries should be used.
- The call and dialer will NOT work with this connection method. The phone is used only as a headset.
Note. There are programs that allow you to dial subscriber numbers from a push-button phone! But, such programs cost several tens of dollars. It is better to spend this money on a SIP adapter, connect to it push-button telephone, and receive / make calls when the computer is turned off (connection method No. 5).
4 way
USB phones
As a rule, a sound card is already built into USB phones. And even if the computer missing sound card, it will not affect the connectivity. If only the computer had a free USB socket.
Unfortunately, often these phones work only as a headset. That is, dialers do not always work (you will have to type with the "mouse"). Almost always work well in "bundle" SIP-program X Lite and "driver" XLiteMate. When using these programs, the dial buttons will also work.
Ringtones are ordinary audio files in a special folder of the program XLiteMate. Melodies can be replaced with your own.
Structurally, such USB phones are made in three options
:
. As mobile phones with a cord - the cost is from 300 rubles;
. As landlines- cost from 1500 rubles (for example, Skypemate USB-P4K);
. In the form of wireless radiotelephones - the price is over 2500 rubles.
The last two points, obviously, are better not to use. It is cheaper and more convenient to use a SIP adapter, connect a push-button telephone to it and receive / make calls when the computer is turned off (connection method No. 5).
USB phones in the form of tubes are convenient when traveling. They can be connected to a laptop. Where there is internet, there is communication!
+ Cordless telephones do not have a cord (the “base” is connected to USB).
+ Desktop devices are familiar in their use.
- When using any USB phone, the computer must be turned on with two special programs: SIP client and "driver" ( latest program usually comes with the device).
This method is convenient for USB handsets connected to netbooks / laptops when traveling and using Wi-Fi in hotels and train stations.

SIP ADAPTER
for conventional (or radio) telephone
By connecting a small adapter to the Internet - to which, in turn, you need to connect a regular push-button phone or a radiotelephone - you can get a full-fledged IP phone that receives and makes calls. In this case, you must not forget to switch the phone to tone dialing mode.
The cost of adapters is from 800 rubles ( Linksys PAP2T on the eBay.com with delivery) and above.
<= Адаптер Linksys PAP2T-NA
The telephone conversation takes place in the usual "style"
+ No one will hear the content of the conversation (relatives, neighbors);
+ Since the computer is not involved in the communication, it may be turned off. Or there may be no computer at all;
- If the adapter does not have a built-in router (router), you must purchase a separate router with 4 ports. The computer will be connected to one port and the adapter to the other.
If the adapter has a built-in router, then the network cable is included in the adapter. The computer is connected to the Internet through an adapter.
Using a SIP adapter to a conventional push-button telephone (preferably a radiotelephone) is perhaps the most convenient and inexpensive option for connecting to a full-fledged IP telephony without using a computer.
When buying an adapter, you should definitely pay attention to how many SIP accounts it supports. This will determine how many servers you can connect to at the same time. The most inexpensive mentioned above Linksys PAP2T supports two accounts on different SIP servers. However, it also requires the connection of two phones at once. In fact, it contains two independent SIP adapters. You can receive calls on one phone (a radiotelephone is convenient), and you can make calls from another landline. Moreover, in this case, you can choose less expensive calls to certain destinations for outgoing calls. After all, all SIP servers have their own tariff plans.

SIP phones
By connecting your IP phone to the Internet, you can receive and make calls. The computer may be switched off or even absent.
Such SIP (and / or Skype) telephony devices are the most complete version of the development of IP telephony.
Some models allow you to connect to several SIP servers at once. When making calls, you can choose the most suitable server for a particular direction and reduce financial costs.
The cost of IP-phones is from 2300 rubles and more.
There are also phones with Wi-Fi handsets.
Phones with screens for video communication cost from 10,000 rubles. and higher.
Despite the rapid decline in the popularity of landline telephones, there are not so many people who are ready to refuse them flatly. Admit it, it happens that sometimes it is extremely difficult or even impossible to do without traditional communication.
To connect the device to the switching network, you need a low-current node, the installation of which you can handle yourself. We will tell you in detail how to connect a telephone socket without calling a wizard.
There is absolutely nothing complicated in the schemes and methods, and the useful information we have proposed, as well as photos and videos, will help to deal with the issue.
Designs of landline telephones are modified and improved every year. And modern devices are significantly superior to their predecessors, standing out against the background of their high reliability and ease of use.
To ensure the smooth operation of the device, two conditions are necessary:
- The presence of a valid communication line from the PBX.
- Possibility of electrical connection of a stationary device to this line.
The only thing that does not change in the field of telephony is the principle of operation of landline telephones. However, there are significant changes in designs and connection methods.
Old and new options for telephone switching are presented in a photo selection:

From the tools for the work it is necessary to prepare:
- building level;
- cross knife;
- voltmeter;
- screwdriver
- wire cutters;
- graphite pencil;
- protective gloves;
- Double-sided tape;
- perforator (if mounting a new point).
When choosing a screwdriver, they are guided by the type of surface and dimensions of the screws used for fastening. To minimize the likelihood of electric shock, it is better to perform all manipulations with a screwdriver, the handle of which has insulation.
Having outlined the installation location of the connection point, using the building level, correct the horizontal and vertical position of its position
To connect a hidden type socket, you must first make a hole in the wall for its installation -. This can be done using a puncher equipped with a special crown with a diameter of 60-70 mm.
In the absence of such, the work can be done with an ordinary hammer with a chisel. But manual labor will take much more time and effort. Then, to the hole made, it is necessary to drill a channel for laying the telephone cable.
There are certain nuances when installing a socket box in.
Stage #2: Stripping the ends of the veins
Before proceeding with the melting of the cores, it is necessary to strip the ends of the wires by removing the outer layer. Bare enough extreme 4 cm of the wire.
When stripping a telephone cable, remember that it is very vulnerable to damage. And broken wires will only lead to equipment malfunction. Therefore, it is important to use a specialized .
Since it is not always possible to carefully cut the first time, experienced craftsmen recommend making some margin along its length when laying the cable. The extra wire can then be hidden under the cover of the device.
Removing the protective insulation from the ends of the cable should be done very carefully, using a cross-cutting knife, a sharply sharpened blade or side cutters.
The task of the master is to strip the ends of the wires from the braid so that in their bare form they are intact and devoid of any defects.
Step #3: Connecting the Outlet Wires
Stripped wires with separated conductors are connected to the connectors of the box itself, focusing on the designations indicated on the front panel of the indoor unit. With a closed installation method, for ease of connection, the wires are made protruding beyond the wall plane by 50-80 mm.
To observe the polarity when connecting wires, they are guided by the rule: red insulation on the line with the “-” sign, and green braid on the “+”
If the polarity rule is not followed, there is a high risk that the telephone will malfunction from time to time during operation.
At this stage of work, you will need a voltmeter. With it, you need to check the readiness of the communication line. The voltage in the line should be in the range of 40-60 volts.
The connected cable cores are applied to the clamp and tightly tightened with special screws, ensuring a secure fit. The shape of the grooves to which the cores are attached facilitates the installation process. It is not necessary to wrap the joints with electrical tape.
When connecting devices, the design of which is equipped with four fork-shaped contacts, only two central contacts are used.
When performing surface mounting, at the final stage it remains only to close the housing cover with a latch and fasten it with screws. The finished outlet is attached to the wall or floor, "planting" it on double-sided tape.
With a closed installation method, making sure that the wires are not intertwined in the socket, according to the applied markings, the indoor unit is mounted in the wall. Having given the block the desired position, the structure is fixed with expansion screws and self-tapping screws.
At the final stage, it remains only to eliminate the gaps between the socket box and the wall, covering it with gypsum mortar, and also close up the channels with the laid telephone cable.
After the gypsum has acquired the desired strength, the protective edging is put in place and the front panel is attached. In modern devices, the protective edging snaps onto the indoor unit, and the front panel is attached by screwing in screws.
There is nothing difficult in connecting a telephone socket. The only thing - you should not save money by purchasing equipment of a low price range. It does not always meet the standards and can fail even at the connection stage.

Home phones have long been part of our lives. In an effort to provide ourselves with maximum comfort, we are increasingly paying attention to radiotelephones, able to satisfy our requests for the convenience of using telephone communications. A cordless telephone is a more complex device than a wired telephone. However, it is not necessary to call the wizard to install it. It is enough to carefully read the instructions and follow a few simple rules.
Instruction
First determine the location where the radiotelephone will be installed. If possible, do not place it near household appliances that are a source of electromagnetic radiation. You should also pay attention to whether direct sunlight falls on the location of the radiotelephone. If you still plan to use the radiotelephone in places of high humidity and heat radiation, do not forget to put a cover on the device or use ordinary packaging film as protection against dust and liquid. So your phone will last longer and keep a neat appearance.
Before connecting the radiotelephone, pay attention to the instructions for charging the batteries, without which no radiotelephone can do. Typically, you need to charge your handset once every few days. When the indicator indicates a full charge or more than half, do not leave the handset in the charger to avoid deterioration of the phone's performance.
Connect the radiotelephone to the network using a modular connector using an adapter. Standard power outlets are not suitable for connecting the power supply, so you should take care of purchasing special adapters in advance.
Remember that the radiotelephone should be handled with care, as the design of the device is very sensitive to mechanical damage. Shocks and drops can shorten the life of the machine or even damage it. Then you will again have to spend money from the family budget on the purchase of a new phone. Do not forget that in the event of a breakdown, you can repair the radiotelephone under warranty, which, as a rule, is for a period of 1 year.
Radiotelephone is a telephone that consists of a base station (base) and one or more handsets (wireless terminals). The base of the radiotelephone is connected to the telephone network, the signal is transmitted between the handsets using radio waves. Such a device, in addition to communicating with the telephone network, can communicate between handsets of the same base. To install a radiotelephone, it is not necessary to call a specialist. You will do everything yourself if you carefully follow the installation instructions.
Instruction
To begin, select the location where the radiotelephone will be installed. It is not desirable that it be located next to a refrigerator, microwave oven, washing machine and other appliances, as well as directly in proximity to metal objects, sources of heat and electromagnetic fields. Also, it is desirable that direct sunlight does not fall on the phone, and high humidity does not affect it.
The best place to install the radiotelephone is determined empirically. If you are installing the radiotelephone in an office, please note that the base units must be installed at least two meters apart. If this is not the case, then it will be impossible to transfer information between the base and the handset.
Before connecting the radiotelephone, charge the battery for the time specified in the instructions, and also set the security code. To do this, place the handset on the base and press the "page" key. The control system will automatically set the code. Repeat this every time you disconnect the base or battery, as in such cases the code is reset and the handset loses communication with the base.
Connect the radiotelephone to the telephone network using a modular connector. It does not fit into ordinary telephone sockets, so purchase an adapter in advance.
The pin connectors of the power supply are also not suitable for standard sockets, connect them to the mains sockets also using the appropriate adapter. Handle the radiotelephone with care, avoid bumps, falls, as the device design contains parts that are quite sensitive to mechanical damage, which can lead to him out of order.
note
Radiotelephones, consisting of a base station and wireless terminals, allow you to communicate confidentially and even do other things at this time.
