My card reader is connected to voice router via ATA, however I cant get it working. I can see that ata is registered with CME and getting IP.
Line seems to be alright, is there any sort of setting that I need to check on ATA?
The ATA186 never supported modem calls. The best it could do was fax passthrough.
Additionally, at least here in the USA, the only reason you use dialup is to largely avoid the PCI-DSS audit. You lose that by connecting it to a VoIP ATA and force yourself into a much more involved audit category. It needs to connect directly to the telephone company equipment as dial-up to avoid violating your merchant agreement.
