ISDN back of a serial interface to multiple locations

Is it possible to backup a serial interface using an ISDN BRI to dial location 1 and in case of failure/unavailability of that, dial to location 2.

interface Dialer1

ip address x.x.x.x

encapsulation ppp

dialer in-band

dialer idle-timeout 300

dialer string xxxxxxxxx

dialer string xxxxxxxxx
