The default setup page of the MitraStar modem/router combo (HGU) provided by Vivo has a bridge mode, but it’s not properly implemented. When it’s enabled, the HGU no longer serves VOIP and IPTV services.
To fix this, you also need to know how to unlock the modem’s advanced settings page, which is blocked by the ISP. This can be done with the following steps:
Unlocking the advanced settings page:
Disconnect the fiber cable from the modem
Hard reset the modem
Connect to the modem’s network either via Wi-Fi or Ethernet
Access the technician’s page at 192.168.15.1/instalador

as the username. The password is the same as the admin
