Update on DAHDI Project

Max Khon has completed the DAHDI Project and provides the following report:

I am pleased to announce the completion of the DAHDI/FreeBSD project.

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.

The main goal of this funded project was to make it possible to use FreeBSD as a base system for software PBX solutions.

Currently, most of the DAHDI bits have been ported, including the DAHDI framework itself, HW drivers, TDMoE drivers, drivers for software and HW echo cancellation (Octasic, VPMADT032) and HW transcoding (TC400B). The project is hosted in the official DAHDI SVN repository.

misc/dahdi in the FreeBSD ports collection now contains the most recent bits of DAHDI/FreeBSD and also some stuff that is not available in DAHDI/FreeBSD SVN due to licensing and copyright restrictions. These include the OSLEC echo canceller and the experimental zaphfc driver.

I will continue periodic merges from DAHDI/Linux SVN on a regular basis and roll out new DAHDI/FreeBSD releases. These will most likely be synchronized with DAHDI/Linux releases.

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.
