POTS Adapter & Dial Up Modem

Hi Pep community. Has anyone used a dial up modem over a POTS Adapter and had any success? The main system I’m working with has a built in dial up modem and relies on an analog line and dials out once a month to send reports. I enabled “data mode” within the POTS Adapter remote web admin, it sort of helped. Now if I keep calling I can eventually connect and data begins to transfer very slowly but the file I’m trying to download never finishes. I’ve adjusted my dial up modem Baud rate from 19200 to 9600 to see if that would help but no luck. Any thoughts?

I would reduce way down, maybe 2400.
I did a fax over it, hadn’t tried a modem yet.

What device are you using with the modem?
How large are the reports?
Do you have any other ports on the device, maybe we could find another solution?
