[asterisk-users] vISDN, mISDN, bristuff [was: Re: Bristuff qozap drivers problem]

[Alberto Pastore]

Same similar problems here, with qozap and bristuff 0.3.0:

with physical media connected, I get a layer 1 down message
that keeps rolling up EVEN DURING AN INCOMING CALL on that BRI span,
and prevents asterisk from placing outbound calls...
until I restart asterisk (luckily, no kernel crashes so far).

Can anyone give me his opion/experience about vISDN or mISDN
alternatives?

Maybe I'm running bristuff in the wrong way, but
I'm starting to think that bristuff is not the best way to make
a stable ISDN PBX.

I don't like very much the way bristuff kind of messes up with
asterisk sourcecode (especially chan_zap/libpri).
