Fax Detect- Switchboard Object

2 min. readlast update: 04.25.2024



  • Fax detect listens to the line for a fax tone and transfers it to the fax service when a fax tone from the calling party is detected.

Use Cases

  • Use Fax Detect to use one number to receive calls and faxes. With fax detect, one may keep their phone number and detect when they receive faxes.

  • This is useful for sales reps and agents on the go.


  • The fax tone comes in every 4-5 seconds, so it might not detect the fax tone before ringing your phone. This may seem like you are receiving ghost calls but Mango is detecting faxes and stopping the phone from ringing. It is recommended to make sure there is a larger delay with a sound clip after the fax detect object or a 5-second wait.
