Yealink SIP-T23G IP Phone 3-Line Gigabit HD Voice SIP Phone Dubai
Yealink SIP-T23G — Exact Gigabit Model for SIP Desk Phone Replacements
The Yealink SIP-T23G is the exact Gigabit version of the T23 desk phone family: a compact 3-line SIP IP phone with HD Voice, dual Gigabit Ethernet, PoE support and a dedicated RJ9 headset port. It is built for Dubai offices that need a reliable wired SIP handset for staff desks, branch users, reception side desks, security cabins, retail counters and small call-handling teams without moving into a larger colour-screen phone.
Vector Digital Systems supplies Yealink SIP phones in Dubai with same-day quote in AED, VAT breakdown, delivery charges and staging before dispatch. Tell David your SIP platform, quantity and PoE availability so the right power and provisioning setup is quoted from the beginning.
SIP, Microsoft Teams or Zoom? Get the Platform Right Before Ordering
The SIP-T23G is a SIP desk phone. It registers to SIP PBX platforms such as 3CX, Yeastar P-Series, Grandstream UCM, Asterisk, FreePBX and hosted SIP providers. It is not a Microsoft Teams phone and it is not a Zoom Phone hardware endpoint. Teams buyers need Yealink MP-series phones, while Zoom Phone buyers need a Zoom-certified Yealink model verified at order stage.
| Your Platform | Right Phone | What You Need |
|---|---|---|
| SIP PBX — 3CX, Yeastar, Grandstream UCM, Asterisk, hosted PBX | Yealink SIP-T23G, if you want this exact 3-line Gigabit model | SIP extension credentials from your phone system |
| Microsoft Teams Phone | 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 — certification status verified before quoting | Zoom Phone licence per user |
PoE Truth — No Power Adapter in the Box
The Yealink SIP-T23G supports Power over Ethernet, but the power adapter is optional. If your switch port supplies PoE, the phone powers through the network cable. If your switch is not PoE-capable, ask David to add the correct Yealink PSU to the quote. This prevents the most common delivery-day issue: the phone arrives, the network point works, but there is no PoE power available at the desk.
Why the “G” Matters — Gigabit Passthrough
The “G” in SIP-T23G matters. This model has dual Gigabit Ethernet ports, so a laptop can sit behind the phone without being limited to 100 Mbps passthrough. For Dubai offices with 1Gbps desk networks, cloud storage, Teams meetings on laptops, browser-based ERP and large file transfers, Gigabit passthrough is a practical reason to choose the T23G over Fast Ethernet entry phones.
Where the SIP-T23G Sits in the Yealink Range
The SIP-T23G is a compact 3-line Gigabit SIP phone for buyers who need the exact older model, a like-for-like replacement, or a cost-effective wired SIP handset with Gigabit passthrough. If you are building a new 2026 fleet rather than matching existing T23G units, ask David to compare it against the newer T31G and T33G options before purchase.

Where the Yealink SIP-T23G Works in Dubai
Branch office desks. The SIP-T23G is a practical fit for small branch teams in Deira, Al Quoz, Jebel Ali and Sharjah where users need a reliable SIP extension, call transfer, call hold, voicemail access and headset support without a large colour display.
Retail counters and service desks. For clinics, trading offices, showrooms, service counters and reception side desks, the 3 SIP accounts cover the common pattern: one main extension, one department line and one overflow or manager line. The Gigabit PC port keeps the counter computer connected through the phone without slowing the desk network.
Like-for-like fleet replacement. If your company already uses SIP-T23G phones and wants the same user interface for replacement units, this exact model avoids retraining. Vector Digital Systems can mirror your existing provisioning template, line key layout and dial plan before dispatch.
Hosted PBX and 3CX rollouts. The SIP-T23G supports auto-provisioning, VLAN/QoS settings, secure provisioning options and SIP registration with common platforms. For UAE integrators deploying multiple desks, Vector Digital Systems can stage the phones in Dubai so the installer only plugs them into the correct PoE port on site.

Staging Before Dispatch — What Vector Digital Systems Configures
Every Yealink SIP-T23G supplied by Vector Digital Systems can be staged before dispatch from Dubai. We load the SIP registration, provisioning template, VLAN and QoS settings where required, BLF or speed-dial keys, dial plan and codec priority, then complete a test call before packing. For multi-branch rollouts, phones can be labelled by branch, extension and user so your installer does not waste time matching MAC addresses on site.

Frequently Asked Questions — Yealink SIP-T23G
What is the exact model name of this phone?
The exact model is Yealink SIP-T23G. The “G” identifies the Gigabit Ethernet version, with dual-port 10/100/1000 Mbps network passthrough for connecting a PC or laptop behind the phone.
Does the Yealink SIP-T23G work with Microsoft Teams?
No. The SIP-T23G is a SIP desk phone for SIP PBX platforms such as 3CX, Yeastar, Grandstream UCM, Asterisk and hosted PBX services. Microsoft Teams Phone deployments need Yealink MP-series Teams phones, with certification verified before quoting.
Does the Yealink SIP-T23G come with a power adapter, or do I need PoE?
The SIP-T23G supports PoE, but the power adapter is optional and should not be assumed in the box. If your switch port is PoE-capable, the phone powers through Ethernet. If not, ask David to add the correct Yealink PSU to the quote.
Will the SIP-T23G work with our 3CX, Grandstream UCM or Yeastar P-Series PBX?
Yes. The SIP-T23G is a standards-based SIP phone and can be used with 3CX, Grandstream UCM, Yeastar P-Series, Asterisk, FreePBX, BroadSoft/BroadWorks and many hosted SIP PBX providers. Vector Digital Systems can stage the SIP registration before delivery.
Yealink SIP-T23G vs SIP-T31G — which one should I buy?
Choose the SIP-T23G when you need the exact older 3-line Gigabit model for like-for-like replacement or a matching fleet. Choose the SIP-T31G when you are building a newer entry-level Gigabit Yealink deployment and do not need the exact T23G interface.
Does the SIP-T23G support Gigabit passthrough for my laptop?
