Right now i am testing that model, max 5 sip accounts, max 5 handsets, 4 simultaneous calls, no provisioning template in 3cx, voice quality OK, you can assign unique extension number to each handset
Yealink W52P
Model Name W52P (SIP IP Phone)
H/W Version 26.0.0.5
S/W Version 26.20.0.10
Calling OK
Call Hold OK
Pickup Call Park OK
Call Park OK
Conference OK
Pickup Call OK
BLINDXfer OK
attendantXfer OK
Call Forward OK
Voice Mail Button/Notification OK
DND OK

I tried to get the W52P and W52PH working in a remote extensions configuration and I can't seem to make that work. I will try the 3CX SIP Proxy Manager next. Can you provide the configuration settings that you used so that might help everyone.
Also, how did you get the 26.20.0.10 version firmware? I have 25.20.0.10!
For remote extension use proxy, i dont have any more that phone, i had it just for test purpose, 26.20.0.10 firmware was already on the phone out of the box
