× Questions about B100/200/400/800 ISDN BRI Cards

2xA1200P + B400P - a few problems...

please check that:
1) if you use misdn-init you have to edit the file to detect the card. please refer user manual
2) if the message appears once or two times, ignore that.

misdn conf files are configured properly, but the problem is that I need to start misdn-init script twice for the card to be recognized. First time the misdn-init script starts during boot (chkconfig) and the second I do it manually (misdn-init restart).

I'm getting the following message in my log file every time I make or receive call over mISDN channel:

Is it normal or....?
It happens on my two asterisk systems. One is working ok (with B100P), but the one I'm working with now is unstable so I'm wondering is it maybe related with those messages?!

Anyone ??

do not meet this bug before, but it looks like something wrong with the mISDN device driver, maybe due to linux kernel imcompatible or bad linux kernel source or you have to compile mISDN again.

what linux you are using?

CentOS 4.7
I'll try now with CentOS 5.2 and mISDN 1.1.7...
