I have a set of Yealink T46G phones. I have a licensed version of 3CX phone system, the latest version. The phones have been reset to factory defaults. I have option 66 defined on my DHCP server as: http: //10.0.0.16/provisioning/15boq3oegc That is where the configuration files are being created by 3CX. I followed the Plug&Play direction on this site with no results: http://www.3cx.com/sip-phones/yealink-t ... t42g-t46g/ I have the phones manually configured and they work fine but I want to control everything from 3CX provisioning. What did I miss?
