Isdn Problems

Hi,

I have a problem with my isdn line.

I have configured a Cisco2621 to connect to a remote isdn router.

When I reboot my router and try to connect to the remote server, my router call up the line and all it's working... but when the line goes down due to remote timeout my router cannot calls up the line once again... (The error is: No Free B CHannel)...

The only way seems to be the router reload...

What can I do?

Thanks to all...

Hello,

which IOS version are you running ? This could be an IOS bug, I have come across it before.

Also, can you post your configuration ?

Regards,

GP
