thanks.... but why the doccd said : Can anyone give some examples ?
The router could match on this dial peer immediately even if there were
another dial peer with a more explicit match and a more desirable route.

The router could match this dial-peer with .T only if there were no other
dial-peer with more explicit match. The router will definitely match the
longest matching destination pattern (in dial-peer), if available. To make a
routing decision, the router will wait until it gets the full dialed digit
string, and then place the call. It will not forward the call immediately
upon a partial match of a dial-peer.

So, in your case you can be assurred that the dial-peer with .T will not
take effect if another dial-peer with explicit match exists.

Hi group,

Grateful if anybody can advise the rules for matching outbound dial-peer ? I
am thinking of the longest match rule but the following extract from the
DocCD does not seem to say so. Are there any good examples ? Thanks very
much, alec

A default route could also be defined by using a single wildcard character
with the timeout T-indicator in the destination pattern, as shown in the
following example:

dial-peer voice 1000 voip
 destination-pattern .T
 session-target ipv4:10.10.1.2

You should be careful, however, when using the T-indicator for default
routes. Remember, when matching dial peers for outbound call legs, the
router places the call as soon as it finds the first matching dial peer.
