I have a CUCM Version 7.0.2
In the Device Defaults I had ATA030203SCCP051201A for Cisco ATA 186.
I loaded ATA030100SCCP040211A.zup into CCM.
In the device phone I changed the "Phone Load Name" to ATA030100SCCP040211A or ATA030100SCCP040211A.zup, saved and reset the device, but the ATA cannot get this new firmware.
I am doing something wrong? Am I missing something?
