Do you have a fax server (like FF110) that can support two or more DID lines?

We only have one fax server (FF110) that supports DID lines. The FF200, FF420, FF820 require analog DTMF lines.
We will have 2 port solution Q3 2007 which uses our CF220DID as a 2 port DID to 2 port FXS.
Analog DID - CF220-DID - FXS - FaxFinder FF420, this would allow 2 incoming and 2 outgoing fax channels.
