I have successfully configured an ISDN dial backup to my T1 line using dialer profiles. I have configured a second dialer profile using the same BRI line to use for a home office to connect into the office. This way I can utilize the backup BRI line while it is not in use. I want to be able to configure the router to automatically disconnect the BRI line if it is in use when the T1 backup needs to occur. I have setup a fast-idle timeout setting which disconnect the BRI in use after 2 seconds of it being idle but if the line is not idle then the dial backup has to wait indefinitely until that line is idle. Is there a command to have the dial backup automatically disconnect the BRI in use so it can use it for backup?
