What kind of modem are you using? Most of the times, it is the issue here.
However, when you place the "backup int asy 1" command, it drops the dtr signal
and goes into standby mode. When the main link is down, there is interesting
traffic and the backup condition (load or time) ocurrs, the router will raise dtr
signal and all the ddr process will be triggered.
Remember your modem is config. to dial on dtr raise.
One suggestion, if you already have it working as ddr, just add the backup cmds.
on the main int.
Hope this helps,
