FreeBSD DAHDI driver project announcement

The FreeBSD Foundation has announced it will sponsor Max Khon to finish the DAHDI FreeBSD driver port.

DAHDI (Digium/Asterisk Hardware Device Interface) is the open source device interface technology used to control Digium and other legacy telephony interface cards.

“The purpose of DAHDI/FreeBSD project is to make it possible to use FreeBSD as a base system for software PBX solutions.

DAHDI (Digium/Asterisk Hardware Device Interface) is an open-source device driver framework and a set of HW drivers for E1/T1, ISDN digital and FXO/FXS analog cards (http://www.asterisk.org/dahdi/). Asterisk is one of the most popular open-source software PBX solutions.

The project includes porting DAHDI framework and HW drivers for E1/T1, FXO/FXS analog and ISDN digital cards to FreeBSD. This also includes TDMoE support, software and HW echo cancellation (Octasic, VPMADT032) and HW transcoding support (TC400B). The work is ongoing in the official DAHDI SVN repository with the close collaboration with DAHDI folks at Digium.

The project is nearing its completion: DAHDI framework and HW drivers telephony cards has been ported and tested. There are a number of success stories from early adopters who use E1/T1 and FXO/FXS cards on FreeBSD for several months.”

Congratulations, Max, for receiving the grant. It’s great to see FreeBSD branching out into another specialist area. AskoziaPBX used to be based on FreeBSD, but hardware support issues made the team decide to move to a Linux based PBX solution. Hopefully we will soon see another fully FreeBSD based PBX system (Askozia, Michael Iedema?)
