In September 2019, Yealink introduced its latest Yealink W80B IP-DECT microcellular system. In this article, we will briefly talk about its capabilities and work with PBX 3CX.
Taking this opportunity, we also want to sincerely wish you a Merry Christmas and a Happy New Year!
Microcellular DECT systems
Microcellular IP-DECT-systems differ from the usual DECT-phones in one important function - support for end-to-end switching of subscribers between base stations (handover), as well as terminals in standby mode (roaming). Such solutions are in demand in specific niches, in particular, in large warehouses, hotels, car dealerships, industries, supermarkets and similar enterprises. We note right away that such DECT systems belong to professional corporate communication systems and cannot be fully replaced by mobile phones (unless maximum savings are at the forefront).
Yealink W80B supports up to 30 base stations in a single DECT network, which together can serve up to 100 DECT terminals. At the same time, HD-quality communication is provided, regardless of the location of the subscriber.
Before implementing a DECT system in an enterprise, it is recommended to conduct preliminary field measurements of the signal quality. For this purpose, Yealink recommends a special measurement kit, consisting of a W80B measurement base station, two W56H terminals, a tripod for mounting the terminals, and two UH33 professional headsets. about the measurement technique.
The W80B base station can operate in three modes:
- DM (DECT Manager) - mode of operation in networks of medium and large size. In this case, one dedicated base works only as a control base (without DECT functions). Up to 30 W80B DECT bases operating in Base mode can be connected to it. Such a network supports up to 100 subscribers / 100 simultaneous calls.
- DM-Base - in this mode, one base station works both as a DECT manager and as a DECT base. This configuration is used in small networks and provides for the connection of up to 10 bases (in Base mode), up to 50 subscribers / 50 simultaneous calls.
- Base is a managed base mode that connects to a DM or DECT-Base.
DECT terminals for microcellular systems
For Yealink W80B, two terminals are offered - upper and middle class.
Yealink W56H
A handset with a large, clear 2.4β³ display, elegant industrial design, powerful battery and various accessories for professional use (which we will discuss later). Tube features:
- Work up to 30 hours of talk time and up to 400 hours of standby time
- Charging from a standard PC USB port or SIP-T29G, SIP-T46G and SIP-T48G phone ports. A 10 minute charge allows you to talk up to 2 hours.
- Hinged clip for attaching the terminal to the belt. It allows the tube to turn, and not break if it is hooked on some kind of obstacle.
- Connector 3.5 mm. to connect a headset.
An additional protective case can be used with the handset, although it does not fully protect the terminal and is not intended for difficult conditions.
Yealink W53H
Mid-range tube designed primarily for industrial applications. Like the older model, it supports the CAT-iq2.0 DECT standard for HD audio transmission. Tube features:
- Color display 1.8β³
- Li-ion battery and talk time up to 18 hours / standby time up to 200 hours.
- Compact design that fits comfortably in any size hand.
- Belt clip and 3.5mm jack. to connect a headset.
This handset is supplied with a professional case with full body protection for use in construction sites, factories, etc.
Both handsets support over-the-air firmware updates from the base station, 3CX address book downloads and all call operations: hold, transfer, conferences, etc.
Connecting Yealink W80B to PBX 3CX
Please note that the Yealink W80B base auto-configuration template only appeared in . So be sure to install this update before connecting. Also make sure the base has the latest firmware. The W80B is currently shipped with the latest firmware, but it is recommended to check the version against , Firmware tab. You can update the firmware by going to the database interface (login and password admin) in the section Settings > Upgrade > Upgrade Firmware.
Please note that DECT terminals do not need to be updated separately. Each handset will start receiving an over-the-air update as soon as it connects to the base station. However, you can update them manually (after connecting to the database) in the same section.
After installing a new firmware, it is recommended to reset the base. To do this, press and hold the button on the base for 20 seconds until all indicators start flashing green slowly. Hold the button until the lights stop flashing, then release - the base is reset.
Setting the base operation mode
Now you need to set the appropriate mode of operation of the base station. Since we have a small network and this is the first base in the network, we will select the hybrid mode DM Base In chapter base mode. Then click OK and wait for the database to reboot. After the reboot, go to the interface - you will see a lot of settings for the DECT manager. But we do not need them now - the database will be configured automatically.
Base configuration in PBX 3CX
As mentioned, the Yealink W80B connection is automated thanks to a special template that comes with 3CX:
- Find out and copy the MAC address of the base, go to the 3CX interface section FXS/DECT devices And click the +Add FXS/DECT.
- Select the make and model of your phone.
- Insert MAC and click OK.
In the tab that opens, specify the method of connecting the base - local network, remote connection via 3CX SBC, or direct remote SIP connection. In our case, we use The local network, because the base and the 3CX server are on the same network.
- Copy the autoconfiguration link, which we will then paste into the database interface.
- Select the server network interface that accepts connection requests (if your server has more than one network interface).
- Note also the new database interface password generated by 3CX. After autoconfiguration, it will replace the default password admin.
- Since the handsets support HD audio, you can install the wideband codec in the first place G722 to transmit HD-quality VoIP traffic.
Now go to the tab Extension numbers and specify the users to be assigned to the handsets. As mentioned, up to 50 3CX users can be selected in DM-Base mode.
After clicking OK, the database configuration file will be automatically generated, which we will load into it later.
Connecting the base remotely via 3CX SBC or STUN (SIP direct connection) requires additional information and has some peculiarities.
Connecting via 3CX SBC
In this case, you must additionally specify the local IP address of the SBC server on the remote network and the SBC port (5060 by default). Please note - you need to on a remote network.
SIP connection directly (STUN server)
In this case, you need to specify the SIP port and RTP port range to be configured on the remote W80B. These ports then need to be forwarded to the base IP address on the NAT router at the remote office.
Please note that in order for all DECT terminals to work correctly, you need to allocate a range of 80 ports for the W600B base.
Also, in the settings of the extension number assigned to the terminal, you need to enable the option Proxy audio stream through PBX.
Specifying the link of the configuration file in the database
Above, when setting up the database in 3CX, we fixed the auto-configuration link and a new access password to the W80B interface. Now go to the database interface, go to the section Settings > Auto Provision > Server URL, paste link, click Confirm, and then Auto Provision Now.
Registration of terminals on the base
After the base is configured, connect the required number of terminals to it. To do this, go to the section Handset & Account > Handset Registration and click the edit SIP account icon.
Then press Start Register Handset.
And on the tube itself, press the button Easy Pairing.
You can also go to the handset menu Registration > Base 1 and enter PIN 0000.
After successful registration, the handset will start updating the firmware "over the air", which takes quite a long time.
Yealink W80B is ready to go!
