asterisk users - Nov 2004 - Asterisk with "chan_misdn" (in USA)

Hello,
Has anyone tried "chan_misdn" in USA?

Does anyone know "chan_misdn" support Lucent 5ess or US National
ISDN-1
protocols?  

I live in North America and I want to connect my BRI Phones (Tone Commander
and Lucent i2021) to the BRI Card in Asterisk.  I was trying to use 
"bri-stuff" S/W but the S/W handles only European DSS1 protocol.

Does anyone living in North America connect any "USA BRI Phones"
to Asterisk successfully? 

Thanks
Ken

The problems lies in the underlying drivers. ISDN4Linux did not support
5ess or NI-1, beyond the HiSax driver, that at some point seems to have
implemented support for NI-1. This is purely TE-mode though (connecting
the ISDN card to a ISDN line). Also of course active cards, like the
Eicon Diva Server ones do 5ess and NI-1.

http://www.isdn4linux.de/faq/i4lfaq-27.html#ss27.6 explains some of the
issues regarding US ISDN.

mISDN is a complete reimplementation of the ISDN4Linux project, that
implements CAPI etc., but no mention of NI-1 or 5ess. Also looking at
the modules, i only find a "l3udss1" module, which tells me that mISDN
probably only supports DSS1 (EuroISDN). This is looking at the CVS
snapshot from 2004-09-24.

You might be better of talking to the ISDN4Linux Team (especially
Karsten Keil) to get this confirmed.
