Using a second internet connection for internet telephony (PVC)

The FRITZ!Box can establish a second internet connection (PVC) for internet telephony (VoIP). If the internet telephony provider supports or requires this, the FRITZ!Box automatically establishes a second internet connection over your DSL line for internet telephony.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephone Numbers" in the "Telephony" menu.
  3. Click on the "Line Settings" tab.
  4. Click "Changing the Settings" in the "Telephony connection" section.
  5. Click "Connection Settings for DSL/WAN".
  6. Enable the option "Use a separate connection (PVC) for Internet telephony".
  7. Click "Apply" to save the settings.

If the option is not available, either the FRITZ!Box automatically hides the option because you cannot use a second internet connection (PVC) with the line, or you have a special FRITZ!Box edition that was produced for a specific DSL or internet telephony provider and is only made available by that provider. Since these editions are tailored to the specific requirements of that particular provider, they do not always contain all of the options.
