CTI Functionality
When the system is connected to a computer, system features can be executed from
the PC. The functionality provided by the connection between a telephone system
and a PC is known as CTI (Computer Telephony Integration).
For example, CTI functionality and other compatible MS-TAPI applications can be en-
abled by TAPI (Telephony Applications Programming Interface) drivers. TAPI drivers
provide an interface between a Windows operating system and a TAPI-compatible
telephone system.
If the system is connected to a PC running as a LAN server, all network clients will
also have CTI capability available.
Comm Server:
This is an application that receives data from the system through a serial port and
then distributes the data to different applications.
● Call detail recording packets
● TAPI packets
● Data administration packets with the administrative tool
CDR data are sent to the CDR application (Call Detail Report Manager) through TCP/
IP sockets. CDR displays CDR information on the PC screen and stores it in text file
format. It also makes CDR data available to a printer or a serial port, for example, for
billing using the Call Report software.
Events for Call Detail Records received from the system are sent through TAPI mes-
sages to a TSP (TAPI Server Provider) using TCP/IP sockets, to provide data to other
applications.
TAPI only monitors physical ports. To operate correctly, a DISA feature must use
special ports, and those cannot be monitored. If a physical port is used when the
DISA feature is active, the TAPI will be able to monitor it.
