The cards were available in ISA, VME, PCI and PCIe bus versions, and were used in PC-based proprietary software solutions for automated telephone systems running on on the Wintel platform, including Microsoft Windows NT/2000/XP, NT Server/Server 2000/Server 2003, as well as Solaris and Linux.
The cards contain up to 18 Motorola 56002, Motorola 56321, or Freescale 56303 DSPs and an Intel 960, Intel 486 or ARMv7 host processor. The cards can handle multiple phone calls simultaneously and route them to the intended point of service. There were several versions that could handle from 24 to 192 voice/conferencing channels on digital ISDN intefaces and from two to 32 analog ports (phone lines).
The Dialogic cards are capable of making and answering calls, identifying caller ID, playing back sounds to the caller and recording sounds from the line, and detecting Dual-Tone Multi-Frequency (DTMF) signals (touch tones) dialed by the caller. They can also tear down a call and detect when the caller has hung up.
Multiple cards can be connected together for increased processing capabilities using proprietary CTBus connector.
Dialogic System Release 6, proprietary software developed by Dialogic Inc., provided predictive dialing, conferencing and interactive voice response (IVR) services which take calls from clients or customers and route the callers to the appropriate individual or data system. The software was used for automated answering services in AT&T, PG&E, Bank of America and other large corporations. Although often complicated and difficult to navigate, these systems allowed corporations to streamline their telephone service and provide information to customers without the need for human interaction.
