You could use:

destination-pattern 4[0,3-9]..

See this link for more information and ideas on how you can use wildcards with destination patterns:

Hi Bill,

Thanks a lot for your reply and the link.

destination-pattern 4[0,3-9] will match only numbers in the raneg 40XX and 43XX-49XXX.

I ws looking for a single destination pattern that will match all 4 digit extensions except 41xx and 42xx (all numbers in the range 1000-4099 and 4300-9999).

Any ideas on constructing the desired range using a single reg-ex?

Thanks,

Bala.

Funny.  Sorry, I just assumed you were concerned with the 4xxx range.  Anyway, for this you will need two dial-peers.

To match: 1000-4099 and 4300-9999

One dial-peer destination pattern: 4[0,3-9]..

The other dial-peer destination pattern: ^0^4...  (which means that the first digit can't be a 0 or a 4)

HTH.
