DAHDI FreeBSD Driver Project

We are pleased to announce that Max Khon has been awarded a grant to finish the DAHDI (formerly known as Zaptel) FreeBSD driver port.

The purpose of the 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 hardware drivers for E1/T1, ISDN digital and FXO/FXS analog cards. Asterisk is one of the most popular open source software PBX solutions.

This funded project includes porting the DAHDI framework and hardware drivers for E1/T1, FXO/FXS analog, and ISDN digital cards to FreeBSD. This also includes TDMoE support, software and hardware echo cancellation (Octasic, VPMADT032) and hardware 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.

This project will be completed in September 2010.
