Faxing with fixed network telephony (IP) and rectifying any faults

Fax with fixed netwk tel. (IP)

You can still continue to fax with fixed network telephony (IP). Insert the fax device and the fixed-network telephone directly into the router. Note that the maximum possible transmission speed for fax with fixed network telephony (IP) is 14,400 bit/s.

We recommend that you connect the fax to a separate telephone number so that your device can accept incoming faxes directly.

Fault rectification

If you have problems sending or receiving fax documents, check the following:

  • Deactivate error correction mode (ECM) on your fax device.
  • Reset the sending speed to 9,600 bit/s. This increases the probability of your fax successfully transmitting the document.
  • Check the parameters of the analogue connection on the fax device. You will find these in the fax documentation/specification.
  • The country setting must be set to “Switzerland”.
  • Impedance should be set to “complex impedance” and not 600 Ohm
  • Frequency dialling: Your fax must be set to tone-dialling operation or DTMF. Impulse dial, also known as Decadic Dialling is no longer supported.
