Telstra FaxStream. Duet (Only for Australia)
In Australia, Telstra offers the FaxStream. Duet capability. This service assigns two numbers to a single telephone line: one for faxes and one for telephone calls. When the fax number is called, the network sends a specific ringing tone which your machine recognizes and automatically handles as a fax call. If the telephone number is called, a different ringing tone is sent out from the network so that the call is handled as a telephone call. This means that there is no switching delay at the caller's end. Contact Telstra for connection information.
  • Triple ring (short-short-short) for fax receiving.
Three short rings, at regular intervals.
  • Any ring except triple ring (depending on your switchboard) for telephone conversation.


  • You need to subscribe to the FaxStream service beforehand.

Caution

Depending on the type of telephone connected to it, the machine may not be able to send or receive faxes properly.
