we have cisco 5520 wireless controller and 2 different aps : AP1852E and AP1810W
device version is 188.8.131.52 .
we have voice ssid in the campus network
dect phones connected to voice ssid work properly inside the building without any delay or data loss during phone conversations
however , one of the floors in the building is surrounded with glass and the connection fails or conversation failures occur when the user is on this floor
what can be the reason behind this situation
I would suggest first check the RF coverage in that floor. I would check what power level those AP operate as well.(assume you doing voice in 5GHz band)
If coverage is good, and failures are reproducible then do a "debug client <mac_addr>" output for one client while this issue is happening. That will give us some indication for client failure
*** pls rate all useful responses ***
dect telephone use 802.11bg i guest 2.4Ghz
when we change 802.11a /802.11an telephone connect to ssid low signal
debug file attached post if you want see
can't see debug file is attached. Pls check
If it is on 2.4GHz, it could be challenging to run voice services, unless you environment is very clean on 2.4GHz band.
I would check what power level AP operates & see you get proper coverage in 5GHz.
"show client detail <client_mac_addr>" output should provide some valuable information about RSSI,SNR to see if client get good signal.
