Last year I upgraded from 4.1.3 to CUCM 8.5 and it seems like over the past year I have been losing my ATA 188 devices. They worked fine after the upgrade but as time progressed they are no longer able to register. I know there is not a load for the 188 in CUCM 8 but they did work fine for a while. I'm curious if anyone else has ran into this issue. I have been replacing them with 186 units which work fine. The RTMT tool will show some of the 188 devices with a StatusReason of "DeviceNumberMismatch" when I looked this up it looks like a SIP error but these devices are SCCP.
I have accumulated a pile of 188s now wondering if they are useless or if there is some way to get them working again.
