Hello Jackie,

I have some doubts that multiple dialer strings are supported in the same interface.



you may need to use multiple dialer interfaces that attempt to dial the different numbers.

at IP routing level you can provide preference to a dialer using different admin distances

ip route dialer1 10

ip route dialer2 20

the time to move from one attempt to the other should be of some seconds

Hope to help
