Call Data Networking Requirements - Nortel TAPI User Manual

38 Chapter 1 Overview
Symposium TAPI SP extracts the HLOC from the network CLID and searches the
IVR host database table to locate the IP address of the TAPI server at the site
associated with this HLOC. The IVR host database table is configured during
initialization and contains the HLOC and corresponding IP address of all
participating TAPI servers in network. When an IP address is found, Symposium
TAPI SP sends a TCP/IP message requesting call data for the network CLID to the
remote Symposium TAPI server.

Call data networking requirements

The requirements for call data networking are as follows:
• All switches must be on an ISDN trunk.
• The NACD application must be installed on the Succession switch.
• Each switch must have a unique HLOC.
• To communicate with each other, all Symposium TAPI servers must be
running release 2.2 or higher of the service provider software.
• All servers must be visible over TCP/IP, which should be verified by pings.
