Yealink is the most widely deployed IP phone brand in the GCC, and for most organisations the question is not whether to use Yealink but which models. The catalogue is large – several desk phone series, DECT systems, Teams-certified devices, headsets and accessories – and this article organises it by the roles and situations a business actually has.
Desk phone series
- T3 series – entry-level phones with monochrome displays and HD voice for shared desks, warehouses, reception waiting areas and anywhere a basic, reliable phone is needed.
- T4 series – the mainstream range: colour displays, Gigabit pass-through, multiple line keys, headset ports with EHS, and Bluetooth and Wi-Fi options on higher models. The right phone for most desks.
- T5 series – executive phones with large adjustable touch screens, and video on the models with a camera. For managers, reception consoles and video-capable desks.
- Teams and Zoom phones – dedicated models running the native Microsoft Teams or Zoom Phone interface for organisations standardised on those platforms.
- Conference phones – tabletop units for meeting rooms, with expansion microphones.
DECT
Single-cell bases for small offices and multi-cell systems for large sites, with handsets from office models to rugged units for warehouses, clinics and hotels. DECT gives mobile staff an extension on the PBX with call quality that Wi-Fi handsets struggle to match, and multi-cell roaming covers a campus.
Headsets
Wired and wireless headsets, USB and DECT, mono and stereo, for desk phones, softphones and Teams. The choice depends on the platform (a Teams-certified headset for Teams users), mobility (DECT wireless for staff who move from the desk), environment (noise-cancelling microphones for open floors) and comfort for all-day wear. EHS adapters connect wireless headsets to Yealink desk phones so that calls are answered from the headset.

Provisioning and management
Yealink phones auto-provision from 3CX and other supported PBXs. For larger estates, Yealink’s device management platform gives central configuration, firmware and monitoring across sites, and Teams devices are managed through the Teams admin centre. Plan a firmware baseline before rollout and manage from a console rather than phone by phone.
Network essentials
PoE switch capacity for every phone, a voice VLAN, QoS on the LAN and firewall, and TLS/SRTP enabled where phones connect across untrusted networks. These are the difference between a phone system that works and one that is blamed for the network’s faults.
