Nathan,
Can you explain where you see phone numbers in a Guest Access WLAN?
Can you provide a screen shot? There is no phone number details in Terms
of Use that can be optionally displayed, nor in the Local Database user (just
uid/pw with associated Guest Access only Role) on the ZD side. Clients who
connect are only prompted for their Guest Pass code, and once authenticated
the Date and Time the pass expires is shown, but no phone numbers anywhere
along the path...
