2xA1200P + B400P - a few problems...

My configuration:
A1200P (zaptel driver)
A1200P (zaptel driver)
B400P (mISDN + SoftEcho)

Asterisk 1.4.22
Zaptel 1.4.11

1. I'm having problems with misdn-init startup script. It shows that mISDN necessary modules are loaded, but when I use 'misdnportinfo' command to check the channels, I get errors like "There is no card...". Log:

After I restart misdn module (misdn-init restart), 'misdnportinfo' shows configured ISDN channels and the misdn channels are available in Asterisk. Log:

So, everything works but the problem is with starting the misdn modules when boot.

...is kinda problem?!


2. I've read some posts here on forum about "buffer re-sync occur..." message. I got these messages when loading card drivers. Can it be ignored? I need to put this system in production and I don't want to happen something bad


Thanks

hello:
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.
regards!

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?
