How I can check the connection to SIP Server of the VoIP provider?

The blue LED must be illuminated and the handset must not show an error message. In case you are still not able to make a VoIP call, start the Connection Assistant on the handset. Select your VoIP provider and the device will download provider data from an internet server.

  • If an error message is shown there is no active Internet connection.
  • If you can download the provider data, there is an Internet connection and VoIP calls should be possible. Please note, VoIP must be the default connection.
