Voice preference

Hi friends,

I have seen the below configs a few times...

dial-peer voice 3 voip
destination pattern 900
session target ipv4:129.9.1.1
preference 0

dial-peer voice 4 voip
destination pattern 900
session target ipv4:129.9.2.2
preference 1

Yet I don't understand what is it's purpose. There were 2 dial peers, with
different destination IPs, but with the same destination phone number?? So
is this saying from the local router, it will first try to dial to 129.9.1.1
(router B - FXS port1), and if it is busy, it then dials to (router B - FXS
port2)??

If this is the case, on Router B, would the following the correct?

dial-peer voice <1> pots
    destination-pattern <900> <--- same local number on both FXS ports??
    port <1/0/0>

dial-peer voice <2> pots
    destination-pattern <900> <--- same local number on both FXS ports??
    port <1/0/1>

Sorry if this is obvious, but I have no IP phone at hand, so i'm a bit
curious here.

Regards,
Lee
