yes. it is possible with with ssl activated on iis to use management console, myphone portal and provisioning, but some things are missing:
- option in 3cx assistant to use https, when opened my phone portal
- option in management console to use https in welcome email for provisioning
enabling ssl on iis is an admin task, so is not neccassary to be an option during installation of 3cx.
