I was using IAXmodem 1.1.1, but because of crash issues I upgraded to 1.2.0. But since then, I have several machines reporting a lot of missing faxs with the message "COMREC received DCN (sender abort)" or "COMREC invalid response received". FYI, all of this machines have BRI cards.
Downgrading to 1.1.1 solved this, but the crashes occur.
Can anyone help? I can send the faxs logs or any other information relevant to help diagnose this.
