VoIP DECT systems for home on the market is presented more than for corporate use. Yealink W52P Representative Wireless Voip Dect Corporate Level Systems Supports up to four simultaneous calls to the base, up to 5 database tubes, powered by Ethernet (PoE), Russian language in the web interface and on the on-screen menu phone The system kit includes a basic station and one wireless tube. Additional Wireless Tube Yealink W52H can be purchased separately.
Wireless telephone system Yealink W52P has all the necessary corporate functions such as retention, translation, call forwarding, 3 third-party conference communication, meals via Ethernet (Power Over Ethernet technology), pajing and intercom. The device works on the SIP protocol, in the composition of supported codecs, in addition to the standard U711 A / U LAW and G.729 enters a broadband codec high Quality G.722 (HD VOICE). The system also has the capabilities of auto-tuning (AutoProvision) and supports centralized corporate reference books.
On the basis of this system, it is impossible to build a micro-distributed DECT system with roaming support around the perimeter, in other words, the tube is registered and operates on a specific base. The system has a large number of settings, despite this, basic setting It has simplicity. Up to 5 independent SIP accounts can be registered, each of which can be fixed behind a certain tube or Yealink W52H tubes. Just like on other DECT-systems, outgoing and incoming routing between tubes and SIP accounts is flexibly adjusted. Registration and re-registration of new tubes on the basis as simple. The number of simultaneous calls through the base is four, in most cases there will be enough such quantity, in this respect the system is leading compared to competitors in its class.
Usage scheme
To 5 tubes (base 1 to n) are recorded up to 5 tubes, then the base is connected by Ethernet to the Switch / PoE Switch (Switch / PoE Switch) depending on the task, the switch can be connected to the router with NAT address translation functions and firewall (Router / Firewall), Base SIP accounts can be connected to the IP telephony provider, to the IP PBX of the client or virtual - the service provider service of the IP PBX. Outgoing and incoming routing through SIP accounts is configured for tubes. Subscribers can move with tubes in the coverage area up to 300 meters outdoors, and up to 50 meters on the territory indoors.

I pay attention to the kit enters the clip for fastening the tube on the belt, which is very convenient. Included everything you need to start work.
On the basis there are three indicators, the first, next to which the tube is depicted, determines the mode of operation of the station if it quickly flashes, the base works in the playing mode, if it blinks slowly, the base is in the mode of registration of new tubes, if it is on constantly, all tubes on the basis Registered. The second indicator, next to which the network icon is shown, is used to indicate the connection to the network, if blinking - the network is not available if the network is on - the network is working normally. The third indicator shows the status of the system if it flashes, software The database is updated or the base during the reboot, if it is on constantly - the base is ready.
The only button on the housing is used for two purposes: the first - with a fast pressing the base will cause all registered tubes, so they can be found, the second - when you press the duration of two seconds, the base will go into the registration mode of new tubes and repeaters Yealink RT10. To one database can be connected to six repeaters, which increases the area of \u200b\u200bthe tubes, three times, for example, when operating in the room - up to 300sel meters. An important feature of the use of repeaters is the ability to connect to one database at the same time to six repeaters and up to five tubes, i.e., as often happens from other vendors, the use of repeaters does not reduce the number of tubes connected to the database. While in the area of \u200b\u200bthe repeater, you can maintain up to two simultaneous conversations and when moving between repeater areas occurs. automatic switching Registration tube without breaking connection (Handover function).
On the basis there are two connectors: RJ45 to connect to the Ethernet network and 5 volts connector to connect the power adapter.
Each Yealink W52H tube comes along with the support employee to charge the tube, on the basis there is a charge indicator if you put the tube to the stand and the indicator lights up, the tube is charging. On the back of the stand there is a socket for connecting the power adapter that comes in the kit.
The tube is made of black plastic with an insert along the edge of silver plastic, has a color LCD screen of 1.8 inches and a resolution of 128 × 160 pixels.
The keyboard on the tube is Russified. The tube is well lying in hand.
Battery compartment for two AAA batteries. Next to the compartment, under the lid there is a mini-USB connector, it is necessary to update the software (software) of the tube. You need a computer to update, a wire with a mini-USB connector that connects to a computer, a specialized software is installed on it, then a new firmware is loaded through this application to the tube.
For the older assemblies, there will be an update on the air tube (i.e., through the web interface, how it happens now for the base). Users will receive this opportunity as follows, 2014. This procedure has become possible thanks to the support of the DECT CAT-IQ2.0 standard tubes, allowing media data through the air. Support tubes of work with a remote notebook is also possible thanks to this standardnot supported by many competitive DECT tubes.
Complete with a tube supplied two metal hydride (Ni-MH) batteries with a capacity of 800mAh.
Rear tube panel with clip set for wearing on a belt.
The tube screen is large enough, but taking into account the resolution of modern mobile phones, the big graininess rushes into the eyes, but for the tasks that the phone solves such permission is enough. You can specify an arbitrary phone name on the screen, in the UCExpert example, the limit of 8 characters, the number 1 on the right on the tube means the serial number of the tube on the database, you can only be 5. 
View of the phone menu, only 6 icons.
This is what the list of menu "Functions" looks like.
Listing the contacts loaded into the phone. Names in Russian, recording can be added independently on Cyrillic.
The list of outgoing calls, on one screen, information about three challenges is placed without scrolling down.
Conversation status, the phone number and the subscriber name in SIP are displayed on the screen (Display Name in SIP), in this case they are the same.
Incoming call to number 10.
In general, working with a tube leaves a pleasant impression, but the screen could be done with a slightly large resolution.
Initial setup
After turning on the base and tube, the tube will automatically register on the database if you need to register an additional tube, hold 2 seconds based on the button "Pagining", then, on the handset, click "OK"More than choose "Settings", then "Registration of the tube" and "Register a handset"then select the desired base, and click "OK". The tube will report a successful registration.
By default, the base works in the DHCP client mode. If you need to install a static IP, click the button. "OK" on the tube, then choose "Settings", then "System" –> "Net", PIN defaults 0000, and click "Done". Now you can mode Static IP / DHCP / PPPoe And edit the settings.
Connect the network database using Ethernet Patch.
What to watch the current IP, click "OK" on the handset, then select the menu "Status", then "State of the system"The current IP settings are displayed, the software version, the MAC address of the base and other system parameters.
It is worth noting that through the tube you can configure a large number of base parameters, but it is more convenient to use the web interface that we will now consider.
Web Interface Overview
Below will be considered some tabs of the web interface.
In my case, the base received the IP address by DHCP equal to 192.168.1.10. To access the web interface, you must open a web browser and enter the IP address in the address period:
http://192.168.1.10
Tab "Status" item "Status"
Tab "Status" Point "Tube & VoIP"
The menu displays the registered DECT tubes, in the VoIP status menu. Registered SIP accounts. In this case, one tube named Ucexpert and two SIP accounts 100 and 101 are registered.
Tab "Account" Point "Basic"
In this menu, the basic setting of SIP accounts of the base, for example, in my case, I register on the virtual IP PBX internal number 100 on the SIP server site using a non-standard port 9966 instead of the usual 5060. To register a SIP account for NAT no additional settings You do not need to specify.
Tab "Account" Point "Extended"
At this point, you can perform a "thin" configuration of the SIP account, for example, change the local SIP port, check the availability of SIP server, re-SIP registration time, type DTMF and other parameters.
Tab "Account" paragraph "Codecs"
Here are selected allowed audio codecs as well as using the buttons "Up" and "Down"selects the priority of their choice. For example, on a local network, if all terminals support the G722 codec (HD Voice), it is better to use it, the sound quality will be significantly higher for external calls to use the standard G711 or narrowband G729
Tab "Account" Point "Routing"
Here is the binding of SIP accounts to the tube, by default, the first tube is tied to the first SIP account, the second to the second and so on, incoming and outgoing calls will come and go through these rules, if you need to adjust the database so that one tube could perform And receive calls immediately from several SIP accounts, you need to put the checks of these accounts.
Tab "Account" Point "Tube Name"
A very useful point that allows you to specify the name for the tube that will be constantly displayed on the screen, for example, I have a name Ucexpert.This name will turn around on the tube when it is registered on the base where this setting is made. Restriction - on the tube can be displayed a maximum of 8 characters, you can specify and more, but the name does not fit on the entire screen. There is also a problem with the display of some letters on Cyrillic, such as the letters to and e, it is solved by the replacement of these letters with the same look at the Latin. In accept, in the name of the tube 2, the letter E is not displayed, instead of a question mark.
Name tube Ucexpert.on the display tube.
Tab "Network" Item "Basic"
Here you can change the main network settings.
Tab "Network" Point "Extended"
The base supports VLAN, connection via VPN, QoS, web access parameters, the RTP port range is indicated here, it is not logical to put it here, since this setting refers to VoIP.
Tab "Phone" item "Settings"
Setting time and synchronization by NTP.
Tab "Phone" Item "Functions"
Here you can specify the settings for each of the 5 lines of SIP accounts, such as employment redirection - I have been configured when busy mobile number, the same, if there was no answer of 12 seconds. Here the keys combinations are configured to quickly turn on redirection modes. Additionally adjust the mode "Do not disturb" – DND. And an anonymous call, when you turn on which most IP telephony operators do not miss the challenge.
Tab "Phone" Item "Update"
Here you can see the current version of the base firmware, update it by loading new firmware Through a web browser, reset to factory settings or restart the database.
Very useful for debugging function - "PCAP magazine"allows you to make traffic dump on the network interface and upload to a computer for further analysis, a network analyzer, such as Wireshark.
Tab "Phone" item "AutoProvision"
Automatic configuration load is configured on this tab. The network has a document in which AutoProvison is described in detail.
Tab "Phone" Point "Configuration"
Tab "Contacts" Point "Contacts"
Here, for each of the five lines, you can manually download a predetermined list of files in one of the formats.csv or.xml, the template for which the file should be created can be downloaded here. Obvious inconvenience - every time you change in the book, it needs to be downloaded for each line again.
Tab "Contacts" Item "Remote notebook"
This option allows centrally viewing contacts from a preloaded file in a specific format, then laid out on the web server..XML,
Name, and update period, default update period of 1440 minutes. The obvious minus is a web server.
Tab "Contacts" Point "Network Book"
Allows you to connect the XSI reference book, to be honest, before that with this way of connecting the network directory, I have not met.
On the last tab "Access" You can change the PIN database code and password to access the web interface.
Positive features:
Good quality manufacturing and good equipment
Support 4x simultaneous calls and 5 Yealink W52H tubes
Russian language support in the web interface
Presence PoE (Power Over Ethernet)
ECO MODE / ECO MODE + MODE + Energy Saving Modes
Negative features:
A little overpriced price, especially for an additional Yealink W52H tube. Let's hope that the situation will change.
No auto-tuning support (Auto-Provisioning) and corporate directory when working with IP PBX YEASTAR
Detailed instructions for the phone only in English
The name of the tube cannot contain more than eight characters. The problem with some letters on Cyrillic (for example, the letter K will be a question mark)
Nevertheless, positive features compensate for negative. The phone turned out to be good, its distinguishes stable work, quality of manufacture, good equipment, support for the Russian language and availability technical support in Russian make it good option For the organization of wireless telephony in the office, if there is no roaming between the databases which increases the value of the decision on an order if not on orders, for example, such as Polycom Kirk.
