i-fax set up

[faxmaster]

We are trying to get i-fax working. I think we have the i-fax settings correct but i am unsure how we send the fix. Once we select i-fax from the device (not sure the correct term) do you just put in the destination fax number like we do with a regular fax?

We have a fax server that should be receiving the i-fax and sending it out. At lest that is way we think it should work.
