About the NEC DSX phone system series

Control unit cabinets are designated DSX-40, DSX-80 and DSX-160, based on the maximum number of ports.
With growth to 160 ports, the NEC DSX series is perfectly suited for small to medium sized businesses that require large business capabilities such as VoIP, T1 and PRI.
Additionally, DSX offers capabilities such as built-in Caller ID and built-in 2-port auto attendant that are ideal for small offices.
The cost-effective IntraMail provides sophisticated voicemail and automated attendant features previously available only with expensive add-ons or costly external units. IntraMail includes call answering features such as dial access to extensions, unique day, night, and holiday answering, the ability for multiple companies to share the same phone system, and the capability to dial employees by entering their names instead of extension numbers. IntraMail also allows you to automatically place a return call to the message sender, screen your incoming calls, forward a message to a coworker, or send a call to a co-workers mailbox.
You can program on-site from a phone or from a PC connected to your LAN through a built-in Ethernet or USB port. PC remote programming is available through the Ethernet port or an optional DSP-based modem.
Older DS-series phones will work with the new systems.
Some DS-series circuit boards will work with the new systems.
The 92245 door intercom used with the older DS1000, will work with DSX systems.
