8 analog lines all terminate in an Adtran TA750 channel bank we bought. From there a crossover cable connects to the T100P card in our Asterisk server.
With this arrangement you cannot receive DNIS. There is no way for the telco to transmit the dialed number to you.
We temporarily had regular phones connected to a few of the analog lines and the caller ID information did come through. Are there questions I should ask my provider that will tell me what kind of signalling we use?
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).
