: Individual loads (e.g., .bin , .loads , .sbn ) for all supported Cisco IP phone models (7800, 8800, 7900 series).
What (e.g., ISR 4331) are you upgrading? Which IOS XE version is currently running on that system? What models of Cisco IP phones do you need to register?
If your organization separates GUI deployment from the core telephony services, this specific TAR file can be downloaded and installed independently, provided the main CME files are already present on the router's flash memory. SIP phones may fail to register after a
