An ESI Communications Server combines the power of
a PBX with the ease of use for which every ESI phone
system is renowned. Its feature set, capacities and
scalability ensure:
• Availability of all features
1
, functionalities and tools
ESI offers to increase the productivity of an enterprise.
• Expansion ability to meet shifting demands of
business growth.
Integrated voice mail — A full complement of
practical, easy-to-use voice mail features is standard
on every ESI Communications Server:
• In addition to its call processing ports, an ESI
Communications Server is configured with built-in
voice mail channels. There is no need to balance
voice mail needs at the expense of a customer’s
call-handling requirements.
• Voice mail and other message storage are recorded
at the highest grade of voice quality (64-Kbit/
second sampling).
• Substantial voice message storage ensures
ample capacity for all mailbox users, including
the needs of users enabled with the optional
auto-record feature.
• Support for 12 message-on-hold recordings:
– Three pre-recorded tracks.
– Nine customizable recordings.
• New-message notification can be delivered off-
premises to a phone or pager.
• Leaving messages for up to 65 mailboxes at once is
easy, using ESI’s unique Quick Groups
™
feature.
• ESI’s Quick Move
™
function enables conversations
to be recorded directly into another user’s mailbox.
At the mailbox user’s option, urgent messages can
be treated with priority and delivered first, instead of
on a “first in-first out” basis.
• Several different mailbox types — including group,
broadcast, information, cascade paging, Q & A,
and guest mailboxes — support a wide range of
customer applications.
• Callers forwarded to user or guest voice mailboxes
can reach the called individual at a designated
off-premises “reach me” number.

See the Technical and Features Comparison Chart (ESI # 0450-0447)
for specific feature availability and capacities for all ESI
Communications Servers.
• Each user mailbox is equipped with a Message
Recycle Bin that remembers, and can restore, the
10 most recently deleted messages.
• One or more stations may have a programmable
Virtual Mailbox Key
™
on their stations to allow
easy monitoring of a second mailbox.
Auto attendant — An ESI Communications Server
provides rich, comprehensive auto attendant features:
• 100 branches (six levels deep) to permit the
design of a more natural, caller-friendly answering
environment, including a company directory.
• Virtually unlimited call routing, including
off-premises transfer.
• Three-character dial-by-name for callers to search
through the auto attendant directory and all Esi-Dex
directories to find the desired name.
Flexible conference channels — Each ESI
Communications Server reserves channels for
conferencing. These can be dynamically
2
connected in
multi-party conversations up to 16 channels per
conference. Any combination of conference channels
may be joined together, as long as the originating party
is an ESI Communications Server user. All channels
reserved for conferencing are dynamically balanced for
optimum audio performance.
Shared-office tenanting
3
— Businesses can share a
common telephone system while maintaining a true
separation of various system resources, facilities,
and features:
• Private or dedicated outside lines by line groups.
• Distinctive incoming ring assignments per tenant.
• Separate auto attendant greetings and branches.
• Individual “dial 0” operators, music-on-hold sources,
and paging zones.
• Unique day/night modes of operation.

Dynamic assignment of the conference channels allows for any
combination of members (up to the maximum of 16) per conference
— e.g., on the ESI-1000 or ESI-600, ten four-member conferences
and three eight-member conferences can take place simultaneously.
