A. The ATA 186 supports fax pass-through. It detects the fax answer tone, disables silence suppression, and then renegotiates the coder/decoder (codec) to G.711 u-law or G.711 A-law. It does not support ITU T.38 standard or Cisco proprietary fax relay. Refer to Configuring the Cisco ATA for Fax Pass-through mode for more information on how to configure the Cisco ATA for fax pass-through mode.
