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.

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. The Yealink T57W is specifically designed for executives and busy managers with a heavy call load. Integrated modern technology If the phone is used and has been connected to another PBX system, you have to reset it first . See how to do this here . If this is the first phone in your network, make it a router phone. If you have others choose whether to make this a router phone or specify the router / SBC for this phone.
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 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. First phones were TXX series... so T18P, T20P, T22P, T26P, T28P etc. Higher numbers meant more buttons/bigger phone/more features. (if I remember rightly the T18P didn't even have a screen on it). Here, the P actually designated POE support. So they had T22 and T22P versions, one which only worked with power adapter and one which could be power adapter or POE. Eventually as costs of POE circuity dropped the non-poe models went away leaving only the T2xP models.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). 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.
