Grandstream

To set up a portal for Grandstream first you need to create a template.

Add a Portal

To create a portal go to the Portals tab and click on the New portal button. Enter a name for the portal, and in Hardware select Grandstream. Then, enter a Site ID based on which the path of the portal URL will be defined.

Portal

The Guest Portal URL will be created based on the URL of the Splash Air application followed by the path given by Site ID. Note this URL as it will be required later.

Select the venue and template and click on the Create button.

Portal Settings

You can go to Portals to view the settings for the portal(s) just added.

Clicking on a portal takes you to the details for that portal. It lets you specify additional settings:

Business Name: name of the venue which will be displayed on top of the portal
Expiry: the time in days after which a repeat user will have to enter their data again on the portal
Redirect URL: the URL a user is redirected to after successful portal authorization
Duration (seconds) after email verification: when using "Link" type Flow it is the "Session-Timeout" a user will receive via RADIUS after successful email verification
Duration (seconds): the time in seconds for which a user is authorized on the network

You can click on the Edit button against each entry to modify it if needed.

Grandstream Settings

Login to your account on the GDMS account and go to Settings > Profiles > RADIUS. Add a new RADIUS profile. The IP address and RADIUS secret shared by Splash Networks' support team will be entered here:
