Unity can be enhanced to provide voice mail, mail, fax , text-to-speech, and so on. So in order for Unity to provide a full UM integration , Unity must be interfaced with several elements including a directory , a mail store, IIS and SQL server.
So with all theses , there are 2 types of possible integrations:
- If the mail store is provided by Microsoft Exchange, Unity also integrates with Microsoft Active Directory (AD). Then it is required that Unity makes a schema extension to the AD domain, this extension will make grow the AD by up to 10 percent.Here are the Unity extensions:
- User
- Group
- Contact
- Unity location (this class is created)
- An alternative to using Microsoft Exchange as the message store, you can use also Lotus Notes. When Lotus Notes is used as message store, it is required also to implement the module called Domino Unified Communication Service (DUCS).
