We are going to be installing a 3CX phone system soon and the office that will be receiving this phone system also requires the ability to use a dial-up modem for remote customer support. I was planning on using a SPA3102 ATA device, assigning an extension and connecting the PC 56k modem to this device. I know there has been a lot of discussion surrounding faxing and the ATA devices, but I couldn't find anything regarding 56k dial-up modems. My questions are this: 1. Is this supported/will it work? 2. Are there any special considerations I will need? 3. Is there a different device better suited for this?
