Dialogic Telecom Equipment - Refurbished, Used, New

Best Selling

Dialogic voice and fax boards are PCI cards that connect a server to ordinary analog phone lines so the server can answer calls, play and record audio, detect touch tones and send or receive faxes. The boards on this page belong to the Dialogic JCT media family: four-port analog cards with RJ11 line jacks that sit behind IVR, voicemail, fax server, call recording and dialer software in a PC or rack server. They are still bought to keep an existing telephony application running on the same hardware it was built on, or to replace a failed card in a system that cannot easily move to VoIP. NetworkTigers sells Dialogic D/4PCIUFW and D4PCIUF boards refurbished, used and new. Every board is tested before it ships so it works when it arrives.

Which Dialogic board do I need?

Start with the application. Most telephony software that runs on Dialogic hardware is written against a specific board family and driver release, so the safest replacement is the same model that is already in the server, or the model the software vendor names in its hardware list. The D/4PCIUFW, D4PCIUFW and D4PCIUF on this page are all four-port analog JCT boards, so for a four-line analog system any of them is the usual fit; the differences are in the regional variant and the way the part number is printed. Check the physical slot: these are conventional PCI cards, so the host server needs a free full-height PCI slot, not PCI Express. Count the lines you need and add boards in multiples of four. If you are unsure which board your software expects, send us a photo of the card you are replacing and the software name, and we will match it.

Frequently asked questions

Can a four-port analog board handle digital T1 or PRI lines?
No. These boards terminate analog loop-start lines only. A digital circuit needs a Dialogic digital board or a gateway that converts it to analog or IP.

Will an older Dialogic board work in a current server?
It works in any server with a conventional PCI slot and an operating system that the Dialogic driver release supports. Many customers keep an older server running specifically for this card, since newer motherboards often have no PCI slot at all.

Do the boards come with the Dialogic software?
No. The board is hardware only. Drivers and the System Release software come from the application vendor or the Dialogic support channel your software was built on.
