Hello, I have an ecosystem consisting mainly of Cisco SPA series phones, but I have just installed a Yealink CP860 conference phone. I had to change the DHCP options on the router for TFTP option 66 to http://ipaddr:5000/provisioning/xxxxxxxxxxx/$MA.xml in order to get the phones to be directed to the 3CX server for the firmware and configuration. When I configured the Yealink phone on 3CX, the URL was different; http://ipaddr:5000/provisioning/xxxxxxxxxxx. What will happen when one of the Cisco phones reboots and attempts to hit that provisioning link? Should I remove option 66 from the DHCP server until I need to install another phone? Also, the Yealink's web interface changed after provisioning. It now requires SSL and is not accepting the default admin/admin login. What should that be now?
