I am thinking of getting a Sangoma A200. We have a fax machine we need to hook up to Elastix. Elastix is going to be set up with SIP trunks going over a dedicated T1. I was thinking that I would have to have an analog POTS line for faxing. On Sangomas product page though it says this. So does this mean that I wont need the analog line or is this a different T1 than I am thinking. Is a Voice T1 different from an internet T1 with SIP trunks. Right now we have a PRI but we are going to get rid of it.
