CTI Computer Telephony Integration
This section of our technical library presents information and documentation relating to Computer Telephony and Computer Telephony Integration software and products.
Computer Telephony Integration CTI software is a rich set of phone software library routines that enable application programs to control your phone system.
This comprehensive CTI software lets you increase employee productivity, enhance customer service and reduce costs by combining the capabilities of our PACER phone system with the custom functionality of your Windows, Unix or Web applications.
Data collected by your phone ACD (Automatic Call Distribution) or IVR (Interactive Voice Response) systems can be passed to your existing PC, Unix or Web applications through our phone software.
The PACER predictive dialer can automatically call your customers and pass only connected calls to your agents. With our computer telephony software, your telephone and computer work together to provide cost-saving benefits.

T1: 1.544 Mbs leased line.
TAPI (Telephony Application
Program Interface): Allows and simplifies Windows ’95, NT, to program and
install telephony devices into many application
programs, irrespective of who made it.
TBD: To Be Determined
TCP/IP (Transmission Control
Protocol/Internet Protocol): Transmission Control Protocol/Internet Protocol,
the suite of
used to connect
hosts on the
two main ones being
IP. TCP/IP is
built into the
and is used by the Internet, making it the
de facto standard
network operating systems
that have their own protocols, such as
Put another way, it is a networking
protocol that provides communication across
interconnected networks, between computers with diverse
hardware architectures and various operating systems. Over time “TCP/IP” has been used in industry to denote
the family of common Internet protocols)
common line between two switching systems. Phone co.
connection to PBX’s.
TUI (Telephone User Interface): Like
GUI but uses digital phones
(User Datagram Protocol):
like TCP, runs on top of IP networks. Unlike
provides very few error recovery services, offering
instead a direct way to send and receive datagrams over
an IP network. It's used primarily for
messages over a network.
VAR (Value Added Resellers):
(Organizations that package standard products with
software solutions for a specific industry)
VLAN (Virtual LAN): A
network of computers that behave as if they are
connected to the same wire even though they may actually
be physically located on different segments of a LAN.
VLANs are configured through software rather than
hardware, which makes them extremely flexible. One of
the biggest advantages of VLANs is that when a computer
is physically moved to another location, it can stay on
the same VLAN without any hardware reconfiguration.
VoIP (Voice Over Internet Protocol): Allows devices of disparate manufacture to support
voice communications over packet networks such as the
Internet. Supports ACD’s and Voice Mail.
VPN (Virtual Private Network):
software-defined network offering the appearance,
functionality and usefulness of a dedicated private
network, at a price savings. In order to operate a
company has to purchase leased lines from their carrier.
WAN (Wide Area Network): A
spans a relatively large geographical area. Typically, a
WAN consists of two or more
local-area networks (LANs).
Computers connected to a wide-area network are often
connected through public networks, such as the telephone
system. They can also be connected through
leased lines or
satellites. The largest WAN in existence is the
