Hello Marcos,

I am not sure about the ISDN switch type, can you try basic-net3 ? Also, try and clear the interface with the command ´clear int bri0´, and reload the router, see if that helps.

Which IOS version are you running ? This might be a bug...

Regards,

Georg

Hi Georg,

I have found the error... After configured all isdn parameter again I use the basic-net3 and it works fine. Now every router can dial out.
