• Conference calls

The X6004 integrates with your IP network. For example you can:
• Import an LDAP-based (Lightweight Directory Access Protocol) contact list to serve as
the phonebook for the IP phones on your network.
• Set up the X6004 to send users email notifications or complete voice messages as
attachments when they receive voicemail.

1.1.3 Scalable Design

The X6004 can be used stand alone to provide intercom (calling by extension) and VoIP
features in a small business environment. The X6004's capability can be expanded by:
• A - Adding DSP (Digital Signal Processing) modules in the device's bottom to handle
more concurrent telephone connections. DSP modules are chips which convert analog
information into digital data and vice versa.
• B - Adding a hard disk to store a greater volume of voice messages and call records.
• C - Connecting several X6004s together to manage a larger telephone network.
