This optional ipbx module is installed under Advanced Setup → Modules. Registered modules are displayed with registered module.
Presence hour warning allows users to set 'working hours'. This means that any calls outside set hours are answered with a warning, local time and the option to complete the call by pressing 1. Optionally callers can also chose to leave a message. Local time information played back, is based off the setting selected in My Timezone and might not accurately reflect the current time as perceived by the user.
Users can select which timezone applies. If not set, the server timezone is used. This is particularly useful when using call-forwarding and follow-me to mobile phones abroad.
Note that call blocking will take precedence over any time warnings.
