Yealink DECT W52P IP Telephone Configuration

The configuration of the terminals certified by VOIspeed should always be carried out with the Autoprovisioning function

Yealink T52P IP DECT Phone Configuration

The Yealink W52P IP DECT phone with default settings automatically searches for a DHCP server on the network during boot to obtain a valid IP address. For the use of the terminal with the VOIspeed Server, the Firmware version is recommended for the Base and version for the telephone


The configuration of the base is done via the web, by connecting with a browser to the IP address of the base which can be obtained from the same mobile phone associated with the base:

  • Click the OK button
  • Click on the Status icon at the top left
  • Select the Base menu: the IP address is visible in the first line of the screen
Alternatively, use a software such as netscan or consult the lease tables of your DHCP server.

The phone included in the package is already paired with its base from the factory, but if it fails to pair, do one of the following.

  • If the phone display reads “Searching for Base”, long press the front button on the base until the Registration LED starts flashing. At this point from the telephone, press the OK button then select Settings -> Registration -> Register Handset to register the telephone: if the PIN is requested, enter 0000 (4 times zero).
  • If the phone display reads “Press base page 2s then press OK”, long press the front button on the base until the Registration LED starts flashing. Then press the OK softkey on the phone (located immediately below the display).

Once connected via the web, the administrator’s username and default password are both admin. Below we indicate the parameters to be modified with respect to the default configuration, referring to a generic user created on the VOIspeed PBX with the following credentials:

In this section it is important to ensure that at least the PCMA codec (G.711) is present.
For the rest it is good to organize the list of codecs in decreasing quality (and, therefore, increasing in terms of bandwidth usage optimization). Codecs T19P

In the Account – Handset Name menu it is possible to assign convenient names to each telephone terminal of the base. This name will appear on the phone display to facilitate traceability. Name Terminals Nome Terminali
In the Number Assignment section it is possible to associate numbers (accounts) and lines to the individual terminals. Change these settings only if necessary. VOIspeed assumes that each DECT phone has one and only one VoIP account associated with it. Assigning Numbers Assegnamento Numeri

Set the following parameters for time synchronization (the base must surf the internet and use a valid DNS server):
Time syncronization: Enabled
Time Server:
Synchronization Period: 86400
Time Zone: +1 France, Germany, Italy …


Set the Select country parameter to Italy

After registering the base to the PBX, in the Toolbox – Terminals section, locate the user agent Yealink SIP-W52P, modify and disable the “click to dial supported” function. In this way, making a call with the GUI, the PBX will first call your phone, which will automatically answer with the speakerphone, then the recipient. If you do not want your phone to answer automatically, disable the Auto Answer parameter from the phone menu Settings -> Telephony User Agent User Agent
To register additional telephones, the same name mode must be activated on the base. This can be done either by pressing the front button on the base until it flashes, or via software from the Status -> Handset & VoIP menu. Press the Start Registration button to put the base into registration mode.
On the phone, press the OKSettingsRegistration -> Register Handset button.


In the same menu it is possible to see the phones currently associated with the base (Registered Handsets table) and the VoIP accounts registered on the VOIspeed PBX (VoIP Status).
Through the Start Paging button, it is possible to make all registered telephones ring. Useful function for tracing terminals if they are lost from sight.
