Well, I am not VoIP expert, so we'll ask the group :)
But my opinion about it:
If the task is "If one call is failed to 3001 remote peer, call another
peer 3002."
With your example no 1. if you dial 3001, it will be routed to 41.0.0.1
And if there is no success, nothing would happen. How will router know
you want to call 3002 then?
With the example no 2, similar. "Preference" command makes sense only
if there are multiple ways to the SAME destination, then choose one
with LOWER preference number value. In your example - there are 2
different destination patterns, so preference doesn't have sense.
I am not sure, but I would try this:
Dial-peer voice 3 voip
preferance 1
Session-target ipv4:41.11.11.1
Destination-pattern 300.
Dial-peer voice 4 voip
preferance 2
Session-target ipv4:41.22.22.1
Destination-pattern 300.
Logic behind it:
If router receives signal 300x where x is anything, he would first
route the call to 41.11.11.1, where is a phone with number 3001. If
there is no success, since he has one more ways how to reach 300x, he
could route the call to 41.22.22.1, where is a phone with number 3002
Well, I've never tried it, I've stayed out of phones in my lab, and
this is just after looking at the "preference" command reference. I am
sure someone could say something smart on this :)

Subject: [RE]Thanks.. !!!
Thank you very much~^^
I got it clearly~
"3T" is any number with starting number 3 if there is no match
particular dial peer. right ??
I have another wondering issue about voip
<Example question>
If one call is failed to 3001 remote peer, call another peer 3002.
I know that the lower voice number remote peer is processed first.
If the call is failed to the lower number peer, automatically call the
next number peer.
Is this right that I understand ??
<Example config>
Dial-peer voice 3 voip
Session-target ipv4:41.0.0.1
Destination-pattern 3001
Dial-peer voice 4 voip
Session-target ipv4:41.0.1.1
Destination-pattern 3002
this config is right ? That's all ?
Otherwise, "preferance" is required ??
<Example config>
Dial-peer voice 3 voip
preferance 3
Session-target ipv4:41.0.0.1
Destination-pattern 3001
Dial-peer voice 4 voip
preferance 5
Session-target ipv4:41.0.1.1
Destination-pattern 3002
which one is right ??
Thanks.

:83=@L : "Niksa Tomulic" <ccie@otokrab.net>
9^4B@L : <ccielab@groupstudy.com>
syntax
R (config-dial-peer)# destination-pattern [+] string [T]
Period (.), which matches any entered digit (this character is used as
a
wildcard)
T - Control character indicating that the destination-pattern value is
a variable length dial string
Result:
"destination-pattern .T"
Your router will interpret like : if you don't have better dial plan
for
the digits dialed, send it there (specified by session target under
same
"dial-peer voice" group)
Example
dial-peer voice 7777 voip
destination-pattern 7777
session target ipv4:10.10.10.1
!
dial-peer voice 8000 voip
destination-pattern .T
session target ipv4:200.200.200.200
If you've dialed 7777, something at the destination "10.10.10.1" should
ring (if properly configured)
If you've pressed anything else, something at the destination
"200.200.200.200" should ring

Subject: VoIP "destination-pattern .T"
In VoIP remote peer configuration,
"destination-pattern .T"
what does it mean??
I don't know exactly about [T]
[T] is dial timeout parameter, right?
"destination-pattern .T"
"destination-pattern 3T"
These statement is only used on remote peer config ??
Otherwise, is it possible on local peer config ??
I don't understand these statements. Plz help me~!!
Thanks in advance
