I recently purchased two WIC-1AM cards that I would like to use over analog POTS to serve as a backup for communications between two Cisco 2621XM routers when the primary Connection goes down. I would like the central router to dial out to the remote sites. I tried to configure this as best I could, but am currently unsuccessful. Any aid you can provide in either auditing my current config and/or implementing this would be greatly appreciated.
