Is there documentation or a whitepaper on how to configure the callhandlers when there are multiple companies being hosted on a Unity UM Server?
For example when you call CompanyA you should hear the Opening Greeting for Company A, when you call CompanyB you should hear the Opening Greeting for CompanyB.
It's not clear to me how to tie a dialed number to a specific Opening Greeting without using a Subscriber Mailbox which uses a license...
