The Yealink SIP-T57W 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. A built-in USB 2.0 port allows you to enjoy USB call recording via USB flash drive. Via this USB port, you also can connect wired/wireless USB headset without connecting Yealink EHS36 anymore, and connect up to 3 Yealink expansion modules EXP50 which can be programmed with up to 180 paperless DSS keys. Then over time they evolved some of the most popular T phones to include gigabit switches. These became the T3x series and were suffixed by "G" to indicate "gigabit"... so T38G, etc
Note: If you don't want to use RPS, you have to enter the provisioning URL into the phone via its web interface. The phone will be configured automatically and then restart. Use the DHCP option 66 if you have a large number of identical legacy phones (as the URL is different for each phone).
Special Environment
The Yealink SIP-T57W IP Phone features a 7-inch capacitive touch screen that you can easily adjust to a more comfortable viewing angle. In addition, the clearly defined set of menus is easy to navigate through when all you have to do is touch the desired option, providing you with an optimised interface for a smartphone-like user experience. HD audio Since the T5X was Yealink's latest "cutting edge" they began rolling out other models into that series to fit requirements outside of just Android. Built-in wifi was one such requirement that I expect they had not originally anticipated but due to requests from customers began to build out. This is where the "W" suffix began appearing. So as part of the "W" roll out (which was somewhere between 1-2 years after the initial T5X) you ended up with:
With the adjustable high-resolution display available on the T57W phone, you can switch angles to your liking and under a variety of lighting conditions. This will ensure an optimized user experience. Enjoy clear calls When the time came to give the T4XGs an internal upgrade to get faster processors/more modern hardware etc, Apply had just pulled their famous "iPhone S!" marketing scheme and I suspect Yealink switched from T4XG to T4XS as a blatant copy of the strategy. (i.e. it's the same phone but faster inside, so let's add an S to say "Super!").Yealink doesn't really breakdown/explain their naming concepts, but having dealt with them for many years I can give you a bit of brief history to help clarify things a bit: The Yealink business phone supports up to four cordless handsets via a DECT dongle. You can now switch calls between the desktop phone and the cordless DECT handset in no time. Yealink knows how important it is for users to have a clean and neat workspace. With the wireless headset's connection to Bluetooth and Wi-Fi, your space will remain uncluttered. Yealink T5 business phones are equipped with an adjustable high resolution display and LED indicators, Android 9.0 OS to improve the data encryption, authority management and more. It includes built-in Bluetooth and Wi-Fi. Each phone can be connected to 4 cordless handsets with the capability of switching calls between the desktop phone and the cordless DECT handset.
