Using ATAs for Fax

All our ATAs support T.38 fax protocol for reliable fax transmission over VoIP. For dedicated fax lines, we recommend:

  • Use a dedicated ATA port for fax (don't share with voice)
  • Configure T.38 passthrough for best reliability
  • Contact us for optimized fax settings

See our ATA Fax Configuration Guide for detailed setup instructions.
