Hello!
Got a self-registration portal with password sendt as SMS to the supplied cellphonenumber.
Now - to avoid internal users using the guest network for their various devices we have a long list of known cellphonenumbers that should be check as a blacklist which should stop registration.
I know you can check for validPhoneNumber and edit the array there, but thats sorta difficult to maintain. The list is already in a php serverpage so ideally it could make a check against this before allowing the registration to complete.
Any thoughts on how to accomplish this?
