With this arrangement you cannot receive DNIS. There is no way for the 
telco to transmit the dialed number to you.

Caller ID is something else entirely; it is _not_ the number that was 
dialed, it is (presumably) the number of the caller.

If you want to receive the number that the caller dialed (so you can 
route the call based on that information), you have only two choices: a 
T-1 from your telco with two-way DID trunks on it, or a PRI from your 
telco. Asterisk does not support any other means of receiving the dialed 
number (and there is only one other means, analog DID trunks).
