I have a new VX231v modem and a new Internet service provider (Vodafone). The Internet works perfectly. However, I have problems connecting the telephone. In the settings, under 'Telephone,' you can select the provider 'Vodafone.' There you can then enter the following data: Telephone number, Authentication ID, Password (optional). Vodafone provided me with the following information: Area code, Phone number, Voice Username, Voice Password. I have already entered the information where I think it would be correct, but it does not work. The fields in the router and the information from Vodafone do not match. What can I do here?
