we have some GPX 1625 with Firmware Version 18.104.22.168, last Week we do upload the new Firmware Update on the UCM to deploy at all GPX Phones works fine. Two GXP1625 has Firmware Version 22.214.171.124 and going into a loop and make not the Update. Factory Reset, DHCP opt., 3CX, don’t helps.
Thanks for reply.
