Computer Telephony Integration
Computer Telephony Integration (CTI) is the linking of telephone communication systems to personal
computers, which can increase productivity and customer satisfaction through the exchange of information
between the PC and the telephone. CTI applications integrate data processing, data communications, and voice
communications.
Avaya IP600 supports the following types of CTI applications.
• Server-based solutions, which require the Avaya CentreVu Telephony server, the
co-resident DEFINITY LAN Gateway (DLG) function (which resides on the
Avaya IP600 TN795 Processor circuit pack) and connectivity to DLG via the
TN795 Processor circuit pack, or optionally via the TN799C C-LAN board.
• Avaya IP Softphones, which enable users to control telephone calls (both
incoming and outgoing) directly from a personal computer.
• www.messenger, which provides quick and easy access to your telephone, fax,
and text messages through your Web browser.
Server-based solutions
Avaya IP600 supports third-party CTI applications via ASAI and TCP/IP links. These
CTI links are supported on Avaya IP600 via the DEFINITY LAN Gateway
functionality, which is co-resident on the Avaya IP600 Processor board (TN795).
The co-resident DEFINITY LAN Gateway supports one ASAI link. The ASAI link is
normally routed from the CTI Server (an external Windows NT or Windows 2000
server) running CentreVu to the TN795 Processor circuit pack via TCP/IP.
For security reasons, the link may be routed from the CTI Server to a C-LAN board
(TN799) in the Avaya IP600 system. The C-LAN board requires use of one additional
slot in the Avaya IP600 cabinet. The maximum message rate over the ASAI link is
100 messages per second full duplex, regardless of whether the link is going directly
to the TN795 Processor board or being routed via a TN799 C-LAN board.
