DAHDI FreeBSD driver port


Project Status: Completed

FreeBSD Developer: Max Khon

Max Khon has been awarded a grant to finish the DAHDI FreeBSD driver port.

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 (http://www.asterisk.org/).

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.

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.

This project was completed in September 2010.
