So, you are saying that the CSIM Start emulation does not match the
behavior of a real phone!?
Hmm. From Brian Dennis' output below it sort of looks like the phone is
doing a "shortest match"!? Well, that is similar to how a POTS phone
works: once you have dialed your 7 digits for a local call, the phone
system ignores any additional digits punched in. And according to your
example, once the VOIP router gets a "1" from the phone it has a match
and uses dial-peer 1.
On the surface this seems to contradict what Brian McGahan was saying
earlier in this thread about the *longer* match for destination patterns
being preferred. Evidently that is only true for CSIM Start? Or only
true for a choice between a 'real' phone number and a wildcard pattern?
Please clarify.
Does the order of the dial-peer statements makes a difference (like it
does in an access list)? Suppose the order were reversed. Would the
phone then match dial-peer 1 for the "12" pattern?
dial-peer voice 1 voip
destination-pattern 12
session target ipv4:10.0.0.1
!
dial-peer voice 2 voip
destination-pattern 1
session target ipv4:10.0.0.1
Obviously voice is not my strong point ....

Alec,
Here is how they would match.
CSIM Start
1) "1" - dial-peer 1
2) "12" - dial-peer 2
3) "123" - dial-peer 2
Phone
1) "1" - dial-peer 1
2) "12" - dial-peer 1
3) "123" - dial-peer 1

dial-peer voice 1 voip
destination-pattern 1
session target ipv4:10.0.0.1
