DIALOGIC CONNECTS INTERNET TELEPHONY AND CTI
LAS VEGAS, NV April 14, 1999 Dialogic Corporation (NASDAQ:DLGC),
the global leader in open computer telephony, is demonstrating a versatile interface
between Internet telephony and computer-telephone integration (CTI) applications at the
Voice on the Net (VON) conference this week in Las Vegas. This gatekeeper-based technology
will extend the capabilities of Dialogic's CT Connect, the leading call control
software, by allowing applications to monitor and control IP telephony calls in the same
way they currently do in traditional telephone environments.
This new technology will allow CTI applications to operate within Internet protocol
(IP) telephony environments as easily as in a traditional PBX. This transparency between
IP telephony and traditional PBXs means that CTI developers will be able to market their
applications for use in IP telephony environments with little or no change. Customers will
then be able to use IP telephony in conjunction with contact management, customer service,
and support applications.
Bringing Call Control to IP Telephony
"Being able to manage IP telephony calls the same way as traditional dial tone
calls is an important capability for application developers," said Cliff Wener,
executive director of the CTI Lab at Williams Communications Solutions, a prominent
supplier of CTI solutions and a Dialogic CT Connect partner. "This technology will
allow us to sell and install CTI applications across a variety of telephony environments
in a consistent way."
IP Telephony Gatekeepers
In a standards-based IP telephony environment, the gatekeeper is the focal point of
enhanced call processing because endpoints within its domain consult it whenever a
connection is set up, torn down, or changed. During call setup, for example, a gatekeeper
handles functions such as bandwidth allocation, address translation, access permission,
and call routing. In addition to these standard gatekeeper functions, the enhanced
gatekeeper demonstrated at VON also communicates with the CTI environment by sending or
receiving standard CTI call control messages at the appropriate points in the call
"Because we are enabling communication between the gatekeeper and external CTI
applications, enhanced call processing functions can be managed in those applications
instead of within the gatekeeper," said Carl Strathmeyer, CT Division marketing
director, Dialogic Corporation. "Customers will be able to utilize applications from
several suppliers to manage calls flowing through a common gatekeeper. Furthermore, both
developers and end-users will benefit because the same applications can also be used with
traditional telephony environments such as PBXs."
Dialogic expects to offer this patent-pending gatekeeper technology as a CT-Connect
component later this year. The company is also working with providers of commercial
gatekeeper products and operators of public IP telephony networks to incorporate this
important CTI interconnection technology into their offerings. This gatekeeper-based
technology extends Dialogic's family of IP telephony products, which includes DM3 IPLink
platform, the industry's first complete, single-board H.323 standards-based server
development platform for building IP telephony solutions.
