Subject:   i4b/isdnd panic on incoming call
Message-ID:  <20011027232701.A321@noya>

next in thread | raw e-mail | index | archive | help
Dynalink Winbond PCI ISDN TA
i4b 0.96 (with iwic patch)
FreeBSD 4.3 RELEASE
----------------------------

When I get an incoming call and I let it ring for too long (its fine if I
answer reasonably early), i4b/isdnd reports errors and the connection dies
('ppp -> show all' reports that the connection is open, but I can't ping my ISP).

I can get it up again by killing isdnd and isdntrace, and loggin out and then in again,
but once this has happened it seems like the connection is never the same again, unless
of course I reboot.

If not for the incoming call problem, the connection would stay up for days.

Thanks for any help.
