Yealink SIP-T48U Touchscreen IP Phone in Dubai

David, our Yealink specialist, can confirm stock, accessory bundle, power requirement, and SIP platform compatibility before dispatch.
SIP or Microsoft Teams? Get the Platform Right Before You Order
The SIP-T48U is a SIP phone. It registers to a SIP-compatible PBX such as 3CX, Yeastar P-Series, Grandstream UCM, Asterisk, FreePBX, or a hosted SIP service. It is not the right choice for a Microsoft Teams-only office unless your voice platform is SIP-based behind Teams Direct Routing or an approved gateway architecture. For native Teams Phone users, ask David for the correct Yealink MP-series Teams phone instead.
| Your Platform | Right Phone | What You Need |
|---|---|---|
| SIP PBX — 3CX, Yeastar, UCM, Asterisk, hosted PBX | Yealink SIP-T48U (this page) | SIP credentials from your phone system |
| Microsoft Teams | Yealink MP-series Teams phone — ask David for the current certified model | Microsoft 365 tenant + Teams Phone licence per user |
| Zoom Phone | Zoom-certified Yealink range — ask David | Zoom Phone licence per user |
PoE Truth — Confirm Power Before Delivery
The Yealink SIP-T48U supports PoE, but do not assume a power adapter is included in the box. In most Dubai office installations, the phone is powered from a PoE switch. If your network switch does not provide PoE, ask David to add the correct Yealink power supply to the quote. This prevents the most common first-day installation problem: the phone arrives, but the desk has no PoE power.
Gigabit Passthrough for Laptop Desks
The SIP-T48U has dual Gigabit Ethernet ports, so one network cable can feed the phone and the user’s laptop or desktop. This matters in Dubai offices where desk cabling is limited and users expect 1Gbps network performance for cloud files, CRM systems, video meetings, and remote desktops.
T48U in the Yealink Desk Phone Range
The SIP-T48U is the touchscreen model in the T4U generation. The T46U is the step-down model for users who want a colour display and physical keys without a touchscreen. The T48U is the premium T4U touchscreen choice. For new-generation T7 refresh projects, David can also quote the T77U as the modern touchscreen successor path, but this page is for buyers specifically requesting the same SIP-T48U model.

Where the Yealink T48U Works in Dubai
Executive SIP desks. The T48U is a strong fit for directors, managers, and decision-makers who prefer a large touchscreen interface for calls, directories, transfer, voicemail, and speed-dial access. It gives the desk a premium phone without forcing the customer into a Teams-only device.
Reception and assistant users. With expansion module support, USB headset support, EHS support, and dual Gigabit ports, the T48U can serve reception desks, executive assistants, clinic front desks, and small operator positions where visual call handling matters.
DIFC, DMCC, JLT, and Business Bay offices. The T48U is useful for SIP deployments running 3CX, Yeastar, Grandstream UCM, or hosted PBX. Vector Digital Systems stages the phone before dispatch so the user can plug in and start calling without manual SIP setup at the desk.
