If you want to show the caller-id on the phone display you have to disable the settingĀ always_show_active_call.

This setting isn't manageable via Web interface, if you want to change it you should use provisioning orĀ single setting HTTP request.


Please note that the default value of this setting is changed: before 8.7.3.22 this setting is off by default, after 8.7.3.22 the default value is on.
