IP Telephony
Network-based
telephony using VoIP — voice over Internet Protocol (IP) — is where the future
of telephony lies. IP systems, offered by ESI, are advanced,
network-based business phone systems that combine the best of both the telephony
and data worlds. Voice is delivered via the existing local area network/wide
area network (LAN/WAN) to the desktop.
Overview
- Ultra-high-speed packetized voice communication — IP telephony
systems can can work with either 10Base-T or the much faster 100Base-T, or in
a combined 10/100Base-T network.
- Scalability — The systems can grow from up to 30 central office
(CO) lines supporting up to 58 total ports, to a fully loaded IP 200 system
with up to 66 CO lines supporting up to 192 total ports.
- Powerful voice mail capabilities — Integrated voice mail systems
can feature 16 always-available channels.
- Extensive phone options — These include: IP Feature Phone; Remote
IP Remote Phone; and standard analog sets.
- Advanced phone features — Some examples include Caller ID, live
call recording and screening, ACD, 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. Systems can operate distant extensions 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.
