We have been trying to setup a fax server with analog lines from our G3csiV7. The fax server needs the DTMF tones of the incoming number. We don't have enough VDN's to do this, but I have seen mode code might be able to do the same thing. Problem is mode code isn't turned on. Our local Avaya partner is only interested in upgrading us to all new equipment. Anyone a suggestions on how to make this work?
