i have a site with 3 1240AG APs and several 7920s.
APs are running 123-8.JEA2 (last IOS).
Sometimes i have one way audio between the IPPhones. After debugging i found out the following:
Sometimes (!)when a client is leaving an AP, AP-1 for example, and gets associated with AP-2, AP-2 sends the IAPP Sent Disassociation Notice to the other APs; AP-1 receives the IAPP: Rcvd Disassociation Notice but does not disassosiates the client!
So, 7920 is on AP-2 but AP-1 thinks is on itself!
What could be going wrong?
APs are connected on a 3com office connect but no vlans exist.
Also, all APs have correct MAC-address filtering.
