Hi,

You can use the command "preference" to specify backup destinations with dial peers. Example:

dial-peer voice 2000 voip

preference 1

destination-pattern 2000

session target ipv4:10.1.1.3

dial-peer voice 2001 voip

preference 2

destination-pattern 2000

session target ipv4:10.2.2.3

Lower preference is prefered. Have a look at the command reference for further details, f.e.:

In general it might be useful to have a look at the Solution Reference Network Design guides for voice, which can be found at www.cisco.com/go/srnd

It contains design guides with best practice examples for various scenarios.

Hope this helps! Please use the rating system.
