The Dialogic D/42JCT-U PBX integration board offers advanced digital connectivity to many popular private branch exchanges (PBXs) for unified and Internet-ready call, voice, and fax processing applications in small- to medium-sized enterprises. It is available in a PCI Express (PCIe) version.

Featuring programmable soft-ports capable of supporting voice, fax, call handling, and host-based speech technologies, the D/42JCT-U reduces the cost of ownership for systems requiring multimedia functionality. The universal PBX interface of the D/42JCT-U offers downloadable firmware for a selection of widely used telephone equipment switches. Support for advanced PBX features such as called and calling number identification, message waiting notification, busy lamp fields, and disconnect supervision is useful for developing unified messaging, interactive voice response (IVR), and call management solutions.

By choosing the D/42JCT-U for enterprise applications, developers eliminate the complexities associated with analog or T1 integration, as well as costly investments in proprietary computer-telephone integration (CTI) links.
