I’m having some echo issues with a few ATAs. Some Google searching pointed me to OSLEC but from what I can tell that is only for hardware devices that tie in to the PSTN. I have a purely VOIP only setup. Is OSLEC a possible solution in this case?
From what research I did, OSLEC does work with dahdi and I do have the dahdi_dummy kernel module running but I get the impression that this only works for hardware devices.
