isdn problem with 1603

[mw9999]

I Have a strange one here.
I Have configure two 1603 router to dialer each other.

Sometimes i can get both lines up and sometimes not.

The router opens the first line (64k) and if you do and show isdn active the line shows the connection.

But the second line only comes up now again.

When i debug dialer the output states that the second line is still trying to dialer the first number.
When i debug isdn events it shows the first line connect and disconnect (even thou isdn active shows it connected)

Every so often the dialer will try and redial the number .

I am pulling my hair out , is this an IOS bug ?.

I have also tried dialing a cisco 1720 router and get the same thing.

Has any body got any ideas.

Thanks for the help
