entranceOverview of the VoIP-DECT Yealink W52P system. W52P - a wireless telephone system for VoIP networks from the Yealink company Connecting a base station
Description and appearance of Yealink W52P
Yealink W52P is a wireless SIP IP phone that supports the DECT CAT-iq2.0 standard. It consists of a base station and a cordless handset. The base station can support up to 5 Yealink W52H handsets, making it possible to make 4 calls at the same time. The device allows you to connect 6 repeaters, which will significantly expand the coverage area. Connection of 5 SIP accounts with independent configuration greatly increases the communication possibilities for offices. Thanks to PoE support, the base station does not need to be connected to the mains. The device is completely Russified.
Base station
The base station is made of matte black plastic. There are 3 LED indicators on the front side:
- the state of the tubes;
- connections to a local network;
- the status of the base station.

Installing and configuring the Yealink W52P phone
Base station connection
There are 2 ways to connect power: connecting to a 220V network via a DC 5V adapter and connecting via PoE. Be sure to check with your system administrator when choosing a power connection. It is strictly forbidden to connect the power adapter on PoE (Power over Ethernet) lines.
Using an Ethernet cable, we connect the “Internet” port of the base station to the local network switch.
Connecting the charging cradle and handset
The charging supply is connected to a 220V network via a DC 5V power adapter. Before starting work, you need to put 2 rechargeable batteries Ni-Mn 1.2Vx2800mAh, included in the delivery set, into the handset. Recharge the batteries on the charging cradle, the charging status is displayed in the upper corner of the handset LCD screen.
Registering handsets
After turning on the base and the handset, the latter is automatically registered to the base.
If you have additional Yealink W52H handsets, then you need to register them manually: hold down the “Search” button on the base for 2 seconds, then press “Ok” on the handset and then go to Settings / Handset Registration / Register Handset, select the required base and click "OK". The handset number and name is displayed in the upper right corner of the LCD screen.
Phone setup
The main parameters of the phone can be configured directly through the handset, but it is more convenient to use the web interface.
By default, in the network settings, the phone is configured to automatically obtain network settings from a DHCP server. Therefore, when you connect it to the network, it is automatically assigned an IP address.
If you need to specify a static IP address, you need to enter the main menu of the on-screen interface by clicking the "Ok" button, go to the Settings / System / Network menu, enter the PIN (by default, the PIN code is 0000) and click "Ok", select the connection type and make the necessary settings. In order for the changes to take effect, you must click “Save”.
In order to view the assigned IP address, you need to enter the menu and select the “Status” tab, go to the “System Status”, where you can see the following information:
- The current IP address of the phone;
- Phone's MAC address;
- Software version.
Status
- software version;
- network settings;
- registered handsets;
- SIP registration status.
In the “Handset & VoIP” tab, you can also register additional handsets by clicking on the “Start Paging” button.
Account
The next tab is “Account”, in which the SIP parameters are configured.
This phone supports up to 5 independent SIP accounts. In the account field, select one of the SIP accounts and enter the data for registration. If the phone is not included in a corporate PBX, then the data obtained during registration with any SIP operator will be suitable for using the phone. If the phone is connected to a corporate network, then you need to use the data of your PBX.
Setting up a SIP account:
We configure all SIP accounts in the same way. To switch accounts (lines) from which you plan to make calls, use the keys to the right of the phone screen.
We made the minimum settings for the correct operation of the phone, which took us no more than 5 minutes.
For more detailed customization, consider a few more tabs.
In the "Account" tab there are a few more inserts: advanced, codecs, routing and handset name.
The “Advanced” insert contains the main parameters for setting up a SIP account:
- anti caller ID (you can hide your number when making calls)
- synchronization with the server
- the ability to reject anonymous calls
- enable / disable missed call history
- auto answer
- ringtone
All audio codecs supported by this phone model are presented in the “Codecs” insert. Here you can specify which audio codecs you want to use and which not. The “up” and “down” buttons select the priority of using the codecs.
In the “Routing” insert there is a menu that is necessary for distributing incoming and outgoing calls between the handsets registered on this base.
In the “Handset Name” tab, you can change the names for each of the 5 handsets supported by the base.
After filling in each insert, it is necessary to save the settings made by clicking on the “Save” button.
Network
The Network tab is used to configure network parameters, including Internet port modes (dynamic or static IP address) and PPPoE.
In the “Advanced” tab, you can configure VLAN parameters, QoS for SIP and voice packets, local RTP port, define ports for web access, etc.
Telephone
The next tab is “Phone”, in which the general settings of the phone, the assignment of functions for each line, the dialing rules, and the setting of voice parameters are carried out. The “Settings” tab is a menu for configuring language settings, synchronization settings, and time data.
Using the "Functions" tab, you can set standby modes, set up a transfer, and turn on call history. And also for each line to configure independent forwarding rules, conditions for the "do not disturb" mode, anonymous call and a number for voice mail.
Restarting the phone, updating, as well as resetting to factory settings can be done by clicking on the corresponding buttons in the “Update” tab.
In the “Configuration” tab, you can also import / export the configuration file, export the system log.
In the Dialing Rules, you can create replacement rules, prescribe the area code in advance. Replacement features can be read in the field on the right - “Note”.
Contacts
In the “Contacts” tab, you can record contacts, set up groups, and import / export a list of contacts in .csv format. “Remote Address Book” allows you to display the deleted address book. It is enough to specify the link to the notebook file and the name of the book, which will be displayed in the list.
You can change the password, database PIN, upload trusted and server certificates in the “Security” tab.

There are more VoIP DECT systems for the home on the market than for corporate use. Yealink W52P is a representative of enterprise-level wireless VoIP DECT systems supporting up to four simultaneous calls to the base, up to 5 handsets to the base, Power over Ethernet (PoE), Russian in the web interface and on-screen menu of the phone. The system includes a base station and one cordless handset. The optional Yealink W52H cordless handset can be purchased separately.
The Yealink W52P wireless telephone system has all the necessary corporate functions such as hold, transfer, call forwarding, 3-way conference calling, Power over Ethernet (Power over Ethernet technology), paging and intercom. The device operates on the SIP protocol; in addition to the standard u711 a / u law and G.729, the supported codecs include a high-quality wideband codec G.722 (HD Voice). The system also has autoprovision capabilities and supports centralized corporate directories.
On the basis of this system, it is impossible to build a microcellular distributed DECT system with support for perimeter roaming, in other words, the handset is registered and operates on a certain basis. The system has a large number of settings, despite this, the basic setting is simple. Up to 5 independent SIP accounts can be registered on the base, each of which can be assigned to a specific handset or Yealink W52H handsets. As well as on other DECT systems, outgoing and incoming routing between handsets and SIP accounts is flexibly configured. Registering and re-registering new handsets to the base is just as easy. The number of simultaneous calls through the base is four, in most cases this number will be sufficient, in this respect the system is leading in comparison with competitors in its class.
Usage scheme
Up to 5 tubes are registered for each base (BASE from 1 to N), then the base is connected via Ethernet to a switch with or without PoE (Switch / PoE Switch), depending on the task, the switch can be connected to a router with NAT address translation functions and firewall (Router / Firewall), SIP-accounts of the base can be connected to the IP-telephony provider, to the IP-PBX located at the client's or virtual - located on the side of the IP-PBX service provider. Outgoing and incoming routing via SIP accounts is configured for handsets. Subscribers can move with handsets in the coverage area up to 300 meters outdoors, and up to 50 meters indoors.

Please note that the kit includes a clip for attaching the tube to the belt, which is very convenient. The set includes everything you need to get started.
There are three indicators on the base, the first one, next to which the handset is shown, determines the mode of operation of the station, if it blinks quickly, the base works in paging mode, if it blinks slowly, the base is in the mode of registering new handsets, if it is constantly on, all handsets on the base registered. The second indicator, next to which the network icon is shown, serves to indicate the connection to the network, if it blinks - the network is not available, if it is constantly on - the network is working normally. The third indicator shows the state of the system, if it is blinking, the base software is being updated, or the base is in the process of rebooting, if it is constantly on, the base is ready.
The only button on the body serves two purposes: the first - when pressed quickly, the base will call all registered handsets, so they can be found, the second - when pressed for two seconds, the base will enter the mode of registering new handsets and Yealink RT10 repeaters. Up to six repeaters can be connected to one base, which triples the area of operation of the tubes, for example, when working indoors - up to 300 hundred meters. An important feature of using repeaters is the ability to connect up to six repeaters and up to five handsets to one base at the same time, i.e., as is often the case with other vendors, the use of repeaters does not reduce the number of handsets connected to the base. While in the range of the repeater, you can conduct up to two simultaneous conversations and when you move between the zones of the repeaters, the handset registration is automatically switched without breaking the connection (handover function).
There are two connectors on the base: RJ45 for connecting to a network via Ethernet and a 5 Volt connector for connecting a power adapter.
Each Yealink W52H handset comes with a stand for charging the handset, there is a charging indicator on the base, if you put the handset on the stand and the indicator lights up, the handset is charging. On the back of the stand there is a socket for connecting the supplied power adapter.
The handset is made of black plastic with a silver plastic insert along the edge, it has a 1.8-inch color LCD screen with a resolution of 128 × 160 pixels.
The keyboard on the handset is Russified. The handset fits well in the hand.
Battery compartment for two AAA batteries. Near the compartment, under the lid, there is a mini-USB connector, it is necessary to update the handset's software. To update, you need a computer, a wire with a mini-USB connector that is connected to the computer, specialized software is installed on it, then a new firmware is loaded into the handset through this application.
For phones of older assemblies, the handset software update will be available over the air (i.e. via the WEB interface, as it is now for the base). Users will get this opportunity next year, 2014. This procedure became possible due to the support of DECT CAT-iq2.0 standard handsets, which allows transferring media data over the air. Handset support for Remote Address Book operation is also possible precisely because of this standard, which is not supported by many competitive DECT handsets.
The handset comes with two 800mAh metal hydride (Ni-MH) batteries.
The back panel of the tube with an installed clip for wearing on the belt.
The screen of the handset is large enough, but taking into account the resolution of modern mobile phones, a large graininess is striking, but for the tasks that the phone solves, this resolution is sufficient. On the screen, you can specify an arbitrary name of the handset, in the example UCEXPERT, the limitation is 8 characters, the number 1 at the top right of the handset means the serial number of the handset on the base, there can be 5 of them in total. 
Phone menu view, 6 icons in total.
This is the list of the "Features" menu.
Listing of contacts loaded into the phone. Names are in Russian, you can add entries yourself in Cyrillic.
List of outgoing calls, information about three calls is placed on one screen, without scrolling down.
The state of the conversation, the screen displays the phone number and the name of the subscriber (Display Name in SIP), in this case they are the same.
Incoming call to number 10.
In general, working with the handset leaves a pleasant impression, but the screen could have been made with a slightly higher resolution.
Initial setup
After turning on the base and the handset, the handset will automatically register to the base, if you need to register an additional handset, hold the button on the base for 2 seconds "Pagining", then, on the handset, press "OK", then choose "Settings", then "Registering a Handset" and "Register handset", then select the desired base, and press "OK"... The handset will report successful registration.
By default, the base operates in DHCP client mode. If you need to set a static IP, click "OK" on the tube, then choose "Settings", then "System" –> "Network" The default PIN is 0000, and press "Ready"... Now you can mode Static IP / DHCP / PPPoE and edit the settings.
Connect the network base with an Ethernet patch cord.
To view the current IP, click the button "OK" on the handset, then select the menu "Status", then "State of the system", the current IP settings, software version, base MAC address and other system parameters are displayed.
It is worth noting that a large number of base parameters can be configured through the tube, but it is more convenient to use the web interface, which we will now consider.
Web interface overview
Below we will discuss some of the tabs of the web interface.
In my case, the base received an IP address via DHCP equal to 192.168.1.10. To access the web interface, you need to open a web browser and enter the IP address in the address period:
http://192.168.1.10
Tab "Status" item "Status"
Tab "Status" item "Handset & VoIP"
The menu displays registered DECT handsets, the VoIP status menu displays registered SIP accounts. In this case, one handset with the name UCEXPERT and two SIP accounts 100 and 101 are registered.
Tab "Account" item "Basic"
In this menu, the basic configuration of the base SIP accounts is performed, for example, in my case, I register the extension number 100 on the SIP server on the virtual IP-PBX using the non-standard port 9966 instead of the usual 5060. To register a SIP account behind NAT, do not specify any additional settings necessary.
Tab "Account" item "Advanced"
At this point, you can “fine-tune” the SIP account, for example, change the local SIP port, check the availability of the SIP server, re-registration time, DTMF type and other parameters.
Tab "Account" paragraph "Codecs"
Here you can select the allowed audio codecs as well as using the buttons "Up" and "Way down" the priority of their selection is selected. For example, in a local network, if all terminals support the G722 (HD Voice) codec, it is better to use it, the sound quality will be significantly higher, for external calls use the standard G711 or narrowband G729
Tab "Account" item "Routing"
Here you can configure the binding of SIP accounts to the handset, by default the first handset is tied to the first SIP account, the second to the second, and so on, incoming and outgoing calls will come and go according to these rules, if you need to configure the base so that one handset can make and receive calls from several SIP accounts at once, you need to check the boxes for these accounts.
Tab "Account" item "Handset name"
A very useful item that allows you to specify a name for the handset that will be constantly displayed on the screen, for example, I have a name UCEXPERT, this name will be terminated on the handset when it is registered to the base where this setting is made. Restriction - a maximum of 8 characters can be displayed on the handset, you can specify more, but the name will not fit on the screen entirely. There is also a problem with the display of some letters in the Cyrillic alphabet, for example the letters K and E, this is solved by replacing these letters with the same ones in the Latin alphabet. As a rule, in the name of tube 2, the letter E is not displayed, instead there is a question mark.
Handset name UCEXPERT on the handset display.
Tab "Network" item "Basic"
Here you can change basic network settings.
Tab "Network" item "Advanced"
The base supports VLAN, VPN connection, QoS, web access parameters, the RTP port range is also indicated here, it is not logical to place it here, since this setting refers to VoIP.
Tab "Phone" item "Settings"
Configuring time and synchronization via NTP.
Tab "Phone" item "Features"
Here you can specify the settings for each of the 5 lines of SIP accounts, for example, call forwarding on busy - I have it configured to send to a mobile number when the line is busy, the same thing if there was no answer for 12 seconds. Here you can also configure the key combination codes for quickly enabling the forwarding modes. Additionally, the mode is configured "Do not disturb" – DND and Anonymous call, when enabled, most IP telephony operators will not miss the call.
Tab "Phone" item "Update"
Here you can view the current version of the base firmware, update it by downloading a new firmware via a web browser, reset to factory settings or reboot the base.
A very useful function for debugging is "PCAP Magazine" allows you to dump traffic on a network interface and download it to a computer for further analysis with a network analyzer, for example Wireshark.
Tab "Phone" item "Autoprovision"
This tab is used to configure automatic loading of the configuration. There is a document on the net that details how Autoprovison works.
Tab "Phone" item "Configuration"
Tab "Contacts" item "Contacts"
Here, for each of the five lines, you can manually load a previously prepared list of files in one of the .csv or .xml formats, the template for which the file should be created can be downloaded here. An obvious inconvenience is that every time the book is changed, it must be reloaded for each line.
Tab "Contacts" item "Remote address book"
This option allows you to centrally view contacts from a pre-uploaded file in a specific format, then uploaded to the web server..xml,
Name, and update period, default update period is 1440 minutes. The obvious disadvantage is that you need a web server.
Tab "Contacts" item "Network book"
Allows you to connect the XSI reference, to be honest, I have not met with this method of connecting a network directory before.
On the last tab "Access" you can change the base PIN and password for accessing the web interface.
Positive features:
Good workmanship and good equipment
Supports 4 simultaneous calls and 5 handsets Yealink W52H
Russian language support in the web interface
PoE (Power over Ethernet)
Energy saving modes ECO mode / ECO Mode +
Negative traits:
Slightly overpriced, especially for the optional Yealink W52H handset. Let's hope that the situation will change.
There is no support for auto-provisioning and corporate directory when working with Yeastar IP PBX
Detailed instructions for the phone in English only
The handset name can be up to eight characters long. A problem with some letters in Cyrillic (for example, the letter K will be a question mark)
Yet positive traits offset negative traits. The phone turned out to be quite good, it is distinguished by stable operation, workmanship, good equipment, Russian language support and the availability of technical support in Russian make it a good option for organizing wireless telephony in an office if roaming is not needed between bases, which increases the cost of the solution by an order of magnitude, if not by orders such as Polycom KIRK.
