We have a CISCO WLAN in place with several SSIDs including one on the Voice VLAN. We need to add an additional one using CCKM due to wireless phone roaming issues. Does adding a new SSID to the WLAN cause any outage whatsoever? We are in an environment where even a small amount down time is not acceptable. We are using two 5500 controllers with hundreds of LAP1142N Thank you

We’re having a Cisco Wireless 7925 Audio delay issue. When calls are answered the first 5 to 16 seconds there is not audio available. The issue is sporadic and not easily replicated which makes it very difficult to capture traces. It appears that the wireless is not receiving the ACK in a timely manner once end users accept calls. Continuous scanning was applied to some of the handsets, but it does not appear to have changed the behavior. We were hoping that more persistent connection would eliminate the delay. The issue appears in the following situations: Wireless to wireless Wireless to Cisco desk phones Cisco Desk Phones to Wireless Wireless to external External to Wireless The wireless network is running of 2 Cisco controllers using WPA2-PSK with pre-shared keys. The phones have firmware version CP7925G-1.4.3ES.1 loaded. We are running UCM version 126.96.36.19900-5 Has anyone seen this or have ideas on what can be done?
