HI,
I advise to use routing protocoll for primary lines, and floating route to isdn:
route 0.0.0.0 0.0.0.0 x.x.x.x 200
where is the 200 is a metric, you need to advertise default route with routing protocoll!
Best regards,
Istvan

If you have a switch between main server and two routers in head office, then it is better to configure HSRP toward the main server (with tracking of route to IP subnet of workstations in Branch Office), and IGP (EIGRP, OSPF) on the WAN segment. Also you may use teaming on the server interfaces, for high availability, and use standby IP of HSRP group as default gateway of main server. http://www.cisco.com/en/US/docs/internetworking/case/studies/cs009.html
