We currently have an Asterisk box that is connected to a PRI for outbound/inbound calls. We also have a manual fax machine attached to a Grandstream HT-386 for making outbound faxes.
Our company is a credit card ISO, so we have to reprogram credit card terminals all day long. These terminals can be even more picky that faxes when trying to dial out.
I attempted to hook the credit card terminal into the ATA box, but it couldn’t dial out. Does anyone have any experience with these devices and making them work through an ATA box?
We currently use an analog phone line, but we would like to get rid of that as well.
