# Presence Installation

The Presence Proxy is packaged as an MSL Blade called NPMPresence. It provides basic presence information to the Speech Auto Attendant and is installed as part of the NuPoint UM system. The Presence proxy service remains dormant until a Presence license is purchased. Once licensed, the Presence proxy service becomes fully functional within minutes of being activated on the NuPoint UM server.

See Optional Feature Installation for blade installation instructions.

The Presence Proxy itself requires no configuration, however, configuration is required on the presence server, in Active Directory, and possibly to DNS. See the following topics for detailed configuration instructions:

- LCS Configuration

- OCS Configuration

- Sametime Configuration

- Mitel MiCollab Client Service Configuration
