Hi 3cx pro,
I need setup Phone Provisioning for our ip phone, using PnP method.
For the Yealink ip phone, like model T58, the 3cx dash board can show its MAC address when this phone get online, like below (the 2nd UNPROVISIONED is mine); both phones are in same LAN subnet with 3cx server.

I have checked this url
https://www.3cx.com/docs/manual/configuring-ip-phones/#h.xkv7wjjfv2ck
you guys have any detailed documents about PnP Provisioning method?
as that 3cx url said, the phone need send a multicast message, so I tried to mimic Yealink phone's behavior
1. I send a LLDP multicast message (which can be picked up by 3cx server, I proved it by tcpdump capture); those fields content just same as Yealink's, except MAC address
2. I also send a REGISTER SIP message to 3cx (User-Agent same as Yealink's)
it turns the 3cx dashboard still show UNPROVISIONED for my mock phone
please kindly points any error to me, Thanks so much.
