When a user tries to call another remote user that is registered to another Cisco Unified Callmanager Express, the called party name appears as To fake_Display on the calling phone display while the call is connected.
This error message appears on the remote side phones because the terminating gateway sends an alert message, instead of a progress message, after it receives a call setup message. This happens if the command voice call send-alert is enabled on the Cisco Unified Callmanager Express installed router.
In order to resolve this issue, use the no voice call send-alert command. The terminating gateway will send a progress message after it receives a call Setup message.
