How can I disable or secure the Web interface?

The web interface in the MVP210, 410, 810 series VOIP cannot be disabled. The 'Set Password' option in the program group of the MultiVOIP serial GUI configuration software allows you to configure a User Name and Password. Configure a strong User Name/Password and share it only with those who absolutely need to know it.

Once configured, this User Name and Password will be required to gain access to MultiVOIP configuration via either the web or serial GUI interfaces. I suggest you make a record of the User Name and Password information and store it in a safe place.
