As apart of my company’s business intelligence we wish to create a guest SSID that can capture emails and telephone number can someone help me with this?
several ways to do this, but easiest might be to use facebook login and then use facebook api analytics to pull data.
another would be to create a custom webpage that requires the field of email or phonenumber to be populated for the user to be able to click on the "accept" button.
You could also setup the guest SSID to use SMS authentication using the Twilio integration. It works very well, and is easy to setup even with no experience using Twilio. It will force users to enter their phone number in order to access the WiFi, though it won't provide e-mails if you're after both.
