I have heard many times of the problems using usb with asterisk and app_rpt. So why does it seem that most everyone has gone this route against the above sage wisdom rather than using something more akin an e&m interface like the pci radio cards Jim designed and built or the interface boards that plugged into an fxs? Port and broke out e&m, providing keying by polarity reversal of the battery voltage. Both solutions work rock solid with no issues. Apparently usb not so much and apparently this is a long standing problem with usb. In thinking about this I’m also curious if the design files for the pci radio interface boards may be available as they’d likely be a good start for an update to a more current interface standard.
