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: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.
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.

The Yealink SIP-T57W is a powerful and expandable office phone that delivers optimum desktop efficiency and productivity. Key Features For T53W they were aiming for a lower more basic/common use phone that would fit the same form factor/look consistent with the rest of the T5X series. So just like the T41 that's now at the bottom end of the T4X series, you get the original version (T53W) and the "stripped down bare bones" version T53. 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: The T3x were a stop gap measure as they still had the same form factors as the T2x. To keep up with the times, Yealink introduced the more "modern" T4X designs. Since they also originally had 10/100 and Gigabit variants, those models became T4XP or T4XG depending on the switch built into them. In reality the P variant really only hit low end units, and before long the G version was the defacto.
Upgrade its firmware to the latest 3CX supported version. See how to do this here . Note: If you are planning to install a router phone, read the section below regarding the firmware requirements. 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).Go to for following folders and delete all files and subfolders in them (NOT the root folders themselves though!):
