I want to setup IVR with unity connection version 11.0 which allows outside callers to dial an extension. But I cannot see option to assign telephone number for users without voice mailbox. I have only limited licenses for voice mailbox so I want to add the remaining users without mailbox so that caller can reach them by extension. But I couldn't find option to assign phone number for that users. In unity version 5, there was option to add the users as internet users with telephone numbers. Here I couldn't see that option. How can I accomplish this?
