PBX Integration Board Description
The Dialogic
®
PBX Integration Board is a PCI form factor voice/fax processing
board that can interface directly to several different types of PBXs. The PBX
Integration Board emulates telephones that connect to the supported PBXs.
Application programs using the PBX Integration Board can answer incoming
calls, place outbound calls, record and playback voice files, detect and generate
tones, access the called/calling number ID for calls forwarded or transferred from
within the PBX, access trunk ID for calls originating outside the PBX, send and
receive faxes, and control message notification. The PBX Integration Board also
provides positive disconnect supervision to immediately detect when a caller has
hung up.
If used with one of the supported PBXs, the PBX Integration Board can provide a
flexible platform for developing integrated computer telephony applications.
Developers can integrate current Dialogic
®
D/4x applications on the PBX
Integration Board with few software modifications and create efficient
applications for the PBX by offering value-added features.
