i have a site with 8 1240AG APs and several 7920s and 7921s.
APs are running 12.3(8)JEA.
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 it is on itself, therefore does not send the IP packets to the new AP and we have one-way audio!
What could be going wrong?
APs are connected on a 2960 Cisco switch without vlan configuration.
The same problems exists at another site with similar configuration (1242 & 7920).
