Hi, The phone provisionning is not done using TR-06x as it is not relevant for these endpoints. We use https based provisionning to be closest to vendor specifications. Documentation is here : http://www.wazo-platform.org/documentation/overview/provisio...

Regarding your 1st question : you can pass the provisionning server throw DHCP (it is explained on the doc link)

Regarding your second question : as the process is to deliver a flat file to a phone, it scales easily.
