I am looking for best practice or recommendation on which Wireless Security to use for our IP 7925 phones. We are only starting with about 10 total phones. They will probably stay local to the building they are in, so they will not be roaming between too many APs. We currently do not have a wireless controller. We do have an ACS and Windows Radius servers. As a test, I have a 7925 working on a test AP with Open Security.
