We have an old Lucent DWBS wireless phone system. We implemented a new 802.11G based wireless phone system using Cisco 1142N APs and 2 Cisco WLC.
We are having a weird issue where the new Avaya phones are only getting 1-2 bars even if you are standing next to the AP.
We have not decommissioned our Lucent DWBS system. Could it be interfering with the Cisco 1142N?
