Yealink T43U VoIP/SIP Phone (SIP-T43U)

The SIP-T43U IP phone is a feature-rich business tool for excellent communications and extended functionality. It is a 12-line IP phone that comes with a 3.7-inch large black-and-white screen and the EXP43 support. United Yealink Optima HD Voice technology and wideband codec of Opus, the T43U awards you the superb audio quality and crystal-clear voice communications.

The phone feels quicker and more responsive when performing call features. Moreover, the T43U puts dual USB ports in a phone that makes Bluetooth, Wi-Fi, USB headset and USB recording come true, and you can use any two of them freely according to your needs. The Yealink new T4U series offers the same elegant appearance as the T4 line, but with improvements for greater interoperability and better collaboration.

Accompanied by two USB ports, the T43U is your right-hand man in the office that makes Bluetooth, Wi-Fi, USB headset and USB recording possible, and you can use any two of them freely according to your needs to enrich phone features. Meanwhile, the phone not only has three pages of flexible buttons that can be easily programmed with 21 paperless DSS keys at most, but also can connect up to three expansion modules, for up to 180 additional buttons with a screen-based LCD display and LED system.

Yealink Optima HD Voice technology combines cutting-edge hardware and software with wideband technology for maximum acoustic performance. Being a totally open, highly versatile audio codec, Opus, is designed to perform a higher HD audio quality than other wideband codecs in a high network bandwidth; However, if your current network quality is poor, Opus can provide you with a better audio quality than other narrowband codecs. And its hearing aid compatible (HAC) handset helps the person who is with hearing loss to hear the voice more clearly.

Yealink T4U series supports efficient provisioning and effortless mass deployment with Yealink’s Redirection and Provisioning Service (RPS) and Boot mechanism to help you realize the Zero Touch Provisioning without any complex manual settings, which makes the T4U series simple to deploy, easy to maintain and upgrade. Furthermore, a unified firmware and auto-p template that applies to all T4U phone models, saves even more time and costs for businesses, as well as simplifies the management and maintenance.

Yealink T4U series uses SIP over Transport Layer Security (TLS/SSL), which is the latest network security technology. It’s also compatible with leading soft switch suppliers, such as 3CX, Broadsoft Broadworks. Moreover, it is carried with dual fimrware images that gives you a enterprise-level protection to avoid bricking your system once upgrade failed.

The phone works via PoE (Power over Ethernet) with a traditional power adapter also available (sold seperately).

The absolute bottom line in performance and price.
Digital Storage Capacity: 128 GB, Color: Black
This phone is the bottom line. It's just enough RAM. A nice OLED display. And that is about it. This dog was heaving like it was running a marathon after set up and a restart. Normally I'd buy a refurbished Pixel, but the prices and support dates are out of my budget sadly. Just playing around to see how the menus looked, the UI crashed after hanging for about 45 seconds. I can't say I hate it, there's much worse out there. Hence I'd call this the bottom line, lowest standard.

good
Digital Storage Capacity: 128 GB, Color: Blue
For the price, I found this to be a very complete phone. The screen looks good, the battery lasts a long time throughout the day, and it runs smoothly for everyday tasks. I liked that the initial setup was easy and that the device responds quickly for calls, apps, and social media. A great option for anyone looking for a reliable phone without spending too much.

6 years of support, but set your expectations.
Digital Storage Capacity: 128 GB, Color: Blue
I was a Moto user. Before moving over to Android, I was among the 0% that used a Windows Phone. My needs have been modest, so the idea of shelling out nearly a thousand or more for a phone never crossed my mind. What is important is ongoing support, which rules out every cat-sat-on-a-keyboard brand. It’s also the reason why I switched from Moto over to Samsung; offering 6 years of OS and security support (from initial release) on an entry-level class device is a HUGE PLUS. In the case of this A17, that’s all the way into August 2031. This is NOT a fast phone by any means, however. Playing media and general browsing? Sure. Playing video? Fine. Lots of videos at once like on some social media platforms? Not so much. Taking videos? It's only 1080p. More immersive games? I wouldn’t bother. Between the processor and the 4GB of RAM, some patience will be necessary, especially for folks running lots of apps. There is more underlying “bloat” here; turning off the animations under developer mode along with unneeded services improves the experience a bit, however. The A17 phone case I purchased separately for this arrived labeled as an A26; the glass screen protector as an A16, so apparently this phone shares a very similar design with those models. No 3.5mm jack but there is a micro SD slot which it shares with the SIM tray. The AMOLED screen is a huge plus; great contrast and sharpness, which is NOT common in this entry-level class. It does have NFC for tap to pay, but no wireless charging. Will this win any benchmarks? No. Folks expecting sports car performance at an economy car price will be extremely disappointed. This does not nor will not compare to phones that cost more. However, if your needs are modest, there’s no need to spend $$$ either when this will do the job. --- Edit: Just for added confirmation about ongoing support (or lack thereof), the Moto G17 that was just released at the end of January 2026 does NOT promise ANY OS updates at all. That's a stark contrast to the A17 here with a promise of 6 years of OS and security updates. Edit 2: Wireless Android Auto connectivity has become tedious with the aftermarket generic Android head unit on my vehicle, with the phone often forgetting to connect. The real culprit is that those units are often running hardware and an OS older than what they advertise; it may say 15 on the surface but underneath, it's actually running like 10 or even older. Getting a USB wired-to-wireless CarPlay/Android Auto adapter fixed that; the phone has remembered to connect every time since. For less than $10, it was worth taking that chance.

Bright Screen, Easy to Use, and Reliable for Everyday Life
Digital Storage Capacity: 128 GB, Color: Blue
I’ve been using the Samsung Galaxy A17 5G for a bit now, and overall I’m really happy with it. It feels like one of those phones that quietly does almost everything well without costing a fortune. The first thing I noticed was the display. The large AMOLED screen is beautiful. Colors are vibrant, text is crisp, and it makes everything from scrolling to watching videos feel more high end than I expected. It’s easily one of my favorite features. This phone is also very easy to use and user friendly. The layout is straightforward, settings are easy to find, and everything just makes sense without a steep learning curve. It’s a great option if you want something simple to navigate without feeling overly basic. Performance has been solid for everyday tasks like texting, browsing, and using apps. One thing I did notice is that right after powering it on, the screen can feel a bit sluggish and slightly unresponsive. It seems like the system and background apps are still loading. Once everything finishes starting up, though, it runs smoothly and works great. The camera is another nice surprise. In good lighting, photos come out sharp with natural looking color. Outdoor shots especially look really nice. Low light is a bit hit or miss, but still decent for casual use. Battery life easily gets me through a full day, and the fast charging is really convenient when I need a quick boost. I also like the durable feel of the phone. It’s slim but doesn’t feel fragile, and the expandable storage is a huge plus if you store a lot of photos or apps. A couple minor downsides: it can slow down a little if too many apps are open at once, and low light photos aren’t its strongest area. Overall: This is a dependable, user friendly phone with a gorgeous screen and solid everyday performance. It’s a great choice if you want something simple, functional, and comfortable to use without spending a lot.
