Computer Telephony Integration (CTI)
CTI combines the capabilities of the Strata CTX digital business telephone system with custom
functionality provided by computer applications. This can be provided through the optional Digital
Telephone Integrated PC Interface or a system connection using the LAN connection.
Digital Telephone Integrated PC Interface
For CTI applications, digital telephones interface to a PC that runs the application software using
the Microsoft Telephone Application Programming Interface (TAPI), to provide customized
functionality. The PC must run Microsoft Windows software.
Any TAPI-enabled PC software is compatible with Strata CTX systems. The most common types
of application are database look-up and pop-up screens that provide information on the calling
party. From a Strata CTX system, Caller ID, ANI, DNIS and call processing information can be
passed from the digital telephone to the application computer.
The 3000-series digital telephone uses an integrated PC Interface Unit (BPCI) for TAPI and data
switching simultaneous voice/data applications. The 3000-series digital telephone must be
connected to the system through a BDKU digital station card. The BPCI provides a highly
functional interface for fast, positive call control via a USB port and supports media streaming
with TAPI 2.0 functionality.
Conference Calls
Conference calling enables other people to join your conversation. These additional people can be
inside or outside the Strata CTX system. Any station can set up a conference with other stations or
outside lines. A conference is defined as any time three or more parties join into one conversation.
A maximum of eight parties are allowed into a conference with up to six from outside lines or
standard stations. The originator of the first conference is the “master” and controls adding and
deleting conference parties. The conference “master” can drop off the last added party by using the
&DQFHO button.
Conference On-Hold
A conference call may be put on Hold so that all the remaining conferees remain connected and no
Music-on-hold is applied. The person putting the conference on hold may rejoin the conference by
pressing the
/LQH button on his phone. The Hold state of the conference can be released from
another station by pressing the
/LQH button of that station. At this time, the station that released
the Hold state becomes Conference Master. This enables one person to establish a conference call
for others.
Join Button
Join allows an attendant or digital station user to connect two established calls to each other.
Releasing from Tandem CO Line Connections
This feature enables unattended line-to-line connections for the Strata CTX, freeing the
conferencing analog station or voice mail port for other calls and important tasks. When a tandem
connection is set up with a [DN] button, the [DN] button will go idle after releasing from the
connection. The [DN] can then be used to make or receive calls from the originating digital
telephone.
