IP 40e
ESI’s IP E-Class systems- the IP 200e and the smaller IP 40e - include all the voice and message capabilities of traditional digital phone systems, but in anIP platform that uses your LAN/WAN for one-wire connectivity of all your business phone extensions, wherever they are.

• Scalability
  • IP E-Class can grow from an entry-level IP 40e system (up to 30 Å~ 28 Å~ 6), to a fully loaded IP 200e system (up to 66 Å~ 96 Å~ 30).
    E-Class can handle up to 30 analog station ports and up to 96 Feature Phones; additionally, it can support up to two T1 or PRI high-bandwidth lines. 
• Ultra-high-speed packetized voice communication (IP)
  E-Class can work with either 10Base-T or the much faster 100Base-T, or in a combined 10/100Base-T network. 
• Powerful voice mail capabilities
  The integrated voice mail system includes 16 always-available channels and includes ESI’s exclusive Quick Groups, Quick Move and Virtual Mailbox Key features. Your ESI Reseller can also provide ESI’s innovative Esi-Mail unified messaging.

• Esi-Link (multi-site) support
  Multiple systems can be interconnected across an enterprise’s dedicated WAN, creating virtually seamless connectivity among multiple offices. While some competing systems are unable to provide more than bare-bones phone features in such arrangements, IP E-Class distant extensions operate across your Esi-Link network as though they were local, providing one-button dialing, simplified call transfer, conference calling, and message sharing. 
• Remote Feature Phone capability
  With the rapid growth of DSL and other broadband services, fully functional Remote IP Feature Phones can be deployed to small remote locations such as local sub-offices or teleworkers’ desktops at home.
