We are using WDS and ACS 4.1 for 7921g and 7920 phones. It seems that 7920 is working great with LEAP but 7921g is always reauthenticating against the ACS RADIUS when roaming between APs. 7921g is having a few second gap for voice when romaming and authenticating. We have tested with APs 1242, 1131 and 1121, acs and local radius. Does somebody have the same experiences with 7921g phones?
