Open Architecture Computer Telephony Servers and Tools

CallHandler Origins

We have established a reputation for delivering high value, premium performance products as well as a focused global customer technical support.

A Fresh Approach.... The CallHandler core technology was conceived at a time when systems were nearly all Unix based. These tended to suffer from the following limitations:

be hard to program because of limited use of Rapid Development Environments
limited access from other computer platforms, especially Microsoft Windows systems, on a world-wide basis
needed UNIX specialists to maintain installations, which generally meant end users could not do this and were very dependent on the suppliers
difficult to operate by end users because of non-graphical interfaces
Line density was relatively low per chassis
hardware tended to have limited functionality so multi-function solutions required equipment from a variety of suppliers, which resulted in a deterioration of the support responsiveness
tended to be very expensive per line
The whole industry was cloaked in Jargon which made it very difficult for new users to clearly understand what the technology could offer their business

Dedicated.... to providing a fresh approach to this market, Chelston developed a solution which overcame these basic limitations. Two key elements were chosen to make this possible:

Aculab's multi-function Telephony Card (Prosody), which offered very high functionality in a compact, affordable solution
Microsoft Windows 2000 which is now a very stable Industry Standard offering, Rapid Development environments - such as Visual BASIC, graphical interface for both maintenance and ongoing management, world-wide connectivity for all types of solutions and a very wide support for both telephony and PC hardware and modular application software.

The first product.... which Chelston developed was CallHandler-240, which at the time was the worlds first 240 line system running under MS Windows 2000, using the Aculab Prosody card. This has been further developed to a 2,400 line capacity per chassis, and many tens of thousands of line capability using clustering technology.

In Summary.... CallHandler embodies the following design principles:

Maximum performance and reliability from a system
Uses Industry Standard hardware and software providing 'future proof' solutions
Hardware and Software modularity for total configurability and short time to market
Built in local and remote diagnostics for system maintenance and performance criteria analysis
Uses the minimum number of component suppliers
World-wide connectivity
Complete, well supported solutions

CallHandler.... is for businesses that want to integrate voice, fax, data and networking on one scalable, cost-effective platform, merged with standard PC technology such as the web, databases, graphical user interfaces, and more. Currently able to handle up to 2,400 simultaneous lines per PC/NT box, with on-going continuous development.

Chelston.... are committed to providing our current and prospective customers with reliable, cost-effective and flexible CTI solutions that exceed their expectations.
