• Ultra-high-speed packetized voice communication — Unlike many IP telephony systems that can operate only on 10Base-T Ethernet LANs, the IP Series can work with either 10Base-T or the much faster 100Base-T, or in a combined 10/100Base-T network.
• Scalability — The IP Series can grow from an entry-level IP 40 system (right) with up to 30 central office (CO) lines supporting up to 58 total ports, to a fully loaded IP 200 system (above, shown with three phones) with up to 66 CO lines supporting up to 192 total ports. The IP Series can handle up to 30 analog station ports and up to 96 IP Feature Phones; additionally, it can support up to two T1 or PRI high-bandwidth lines.
• Powerful voice mail capabilities — The integrated voice mail system features 16 always-available channels and includes ESI's exclusive Quick Groups^™, Quick Move^™ and Virtual Mailbox Key^™ features.
• Extensive phone options — These include: ESI's industry-acclaimed IP Feature Phone; IP Remote Phone; a software-based, PC-resident "soft phone"; and standard analog sets.
• Advanced phone features — Some examples include ESI's enhanced Caller ID*, live call recording and screening, ACD, Esi-Dex^™ speed-dialing, built-in message-on-hold, and Verbal User Guide^™.
• 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 Series distant extensions operate 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 IP Remote Phones can be deployed to small remote locations such as local sub-offices or teleworkers' desktops at home.
