[Asterisk-bsd] ISDN driver for FreeBSD (update)

[Hans Petter Selasky]

Hi,

I have just uploaded another pre-release of my ISDN+USB driver, for FreeBSD 
5/6/7. It should be very easy to install.

Here are some of the changes:

- This time I have fixed and tested the Fritz driver, but only "Fritz PnP/PCI 
version 1", "AVM A1" and "AVM Fritz!Card (ISA)", is supported. I have also 
made some improvements to NT-mode. Primary rate, E1, has also got some fixes. 
Also I have fixed some compilation issues with the latest FreeBSD 6.0 
release.

- There is a new utility called "isdnconfig" that can be used to configure the 
mode of the D-channel.

- There is a NetBSD 2.x port of this driver available. See the driver info 
file for more information.


My driver now works well with Asterisk, using the "chan_capi" module. Just 
recently I made the following setup:

Wireless ISDN phone <-> crossover cable <-> HFC-S USB <-> chan_capi <-> 
Asterisk <-> PPP <-> Winbond USB TA <-> internet <-> SIP-provider

And it worked pretty well. Around 33kbit/s was used by the audio stream, 
though it is worth to mention that the sound degraded quickly when I started 
downloading things from the internet. Most likely the problem was that my ISP 
did not give priority to the UDP frames carrying the sound. Using a 128K 
internet connection might improve the situation.


I have put some example configuration files at:

Here is a document that describes some of the supported features:
