Voice Gateways and Session Border Controllers

An engineer has a Cisco UCM cluster running version 12.5(1). The engineer registered and configured a new Cisco IP Phone 8851 with Cisco UCM and assigned it to a user. If Cisco UCM displays the message "Rejected," the issue should be addressed by pressing the gear button on the phone and selecting administrator settings. What is the next action the engineer must take to resolve the issue?

  • A reset settings > reset device
  • B reset settings > all settings
  • C reset device > all settings
  • D all settings > erase
Explanation

For a Cisco IP Phone 8851, the administrator-menu procedure to restart the phone and apply its saved configuration is Admin settings > Reset settings > Reset device. Cisco documents this reset path as the device restart operation; resetting all settings instead restores factory-default configuration.
