What do you mean by 'block' ? What do you want to happen to the call?
I just tried to configure a dial rule on our 4.1.7 alpha test system,
and it accepted it and generated what looked to me like a valid
configuration (I didn't activate the dial plans and test it because it
would have disrupted other users).
So... what did I do?
I configured a Custom dial plan:
Name 'directory redirect'
Dialed Number
Prefix '1xxx5551212' and 0 digits
Resulting Call
Dial '1234' and append Nothing
Gateways
none specified
what that _should_ do is change any call matching that pattern into a
call to 1234, which would then be re-evaluated according to the full set
of routing rules (if you don't specify a gateway, then the call is sent
back to the proxy to be routed further).
I'm pretty sure that would work just fine (and would also work in
4.0.4), and I could replace 1234 with, for example, an auto-attendent
whose prompt says "please dial 411 for directory assistance", or I could
substitute some other external number - whatever I want as long as the
Resulting Call won't also match the Dialed Number rule (infinite loop -
call will fail - be careful).
One thing to note about putting patterns somewhere other than at the end
of the dial string: if you specify that the Resulting Call should
'append "Matched Suffix"', then what will be appended is really the
digits that begin at the first wildcard match and continue to the end,
whether the end includes non-wildcard digits or not. So, in the rule
above if I changed the Resulting call to be Dial 1234 and append Matched
Suffix, and then dialed 17775551212, the call would be 12345551212.
