Dial-Peer Priority

[IP_Cartel]

I have two dial-peers for outgoing.  I want to be able to make dial-peer 1 the priority and when it is unavailable I want it to use dial-peer 2.

The issue I am having is Dial-Peer 2 is always taking precedence over dial-peer 1.  Is there a way to make one of the dial-peers as a preferred dial-peer?  Do I need to use the same voice class? 

Sample dialing 92135551234.  Dial peer 1 strips the 9 as it should, but dial-peer 2 I need it to keep the 9 until it reaches my other voice gateway.  

Voice class e164-pattern-map 2
e164 91[2-9]..[2-9]......
e164 9[2-9]......

You need to have the exact same match statement on both dial peers for the preference to be a factor. Otherwise it will use the best match dial peer. You can alter this behaviour with the dial-peer hunt command. For details on this see this spectacular document. In Depth Explanation of Cisco IOS and IOS-XE Call Routing
