Paul,
No. It will only forward traffic to 10.1.1.2 if there is no
longer match for the destination pattern through another dial peer.
It's the same principle as IP routing. Suppose you have the following
IP routes
ip route 1.2.3.4 255.255.255.255 10.0.0.1
ip route 0.0.0.0 0.0.0.0 20.0.0.2
If you are sending traffic to 1.2.3.4, it will be sent towards
10.0.0.1. If you are sending traffic to anything besides 1.2.3.4, it
will be sent towards 20.0.0.2. Since there is a longer match for
1.2.3.4 than the default route, it takes the more specific forwarding
path.
Suppose you have the following voice config:
dial-peer voice 1 voip
destination-pattern 555-1111
session target ipv4:10.0.0.1
!
dial-peer voice 2 voip
destination-pattern .T
session target ipv4:20.0.0.2
If you dial 555-1111, you'll send the traffic to 10.0.0.1.
Anything else, however, will be sent to 20.0.0.2.

Brian,
Just needed to clarify something. If we have the following,
Dial-peer voice 7 voip
Destination-pattern .T
Session target ipv4:10.1.1.2
Does it mean that when any number is dialed, it will forward it to
10.1.1.2
?
Thanks,
Paul

Paul,
T actually means interdigit timeout. The default interdigit
timeout is 10 seconds. Each time you dial a digit, the router is going
to wait 10 seconds before doing call setup. After 10 seconds have
expired, the router assumes that what you have entered so far is the
complete dial string, and does call setup on those digits. You can
modify the interdigit timeout with the voice-port command 'timeouts
inter-digit'.
The combination of the . (any single character) and the T (wait
for additional characters) effectively defines a default route for
voice.

Subject: Destination pattern symbols
Hi,
Could someone please explain to me what these symbols mean:
Destination-pattern .T
A dot implies a single character right ?
The T symbol implies a variable length dial string.
Does the combination of the 2 symbols mean dial any number ?
Thanks.
Paul
