We have a customer who has a T1 port on their rightfax server. We will need to deliver 4 digit DTMF from the phone system to that T1 port. My first thought is that this will simply come into the 3300ICP, then we will have to route the calls back out and down the T1 to the fax server, even if they are in the same rack. Can anyone think of another way around this?
