The group call feature allows users to call all the contacts simultaneously in a group. Initiating a group call on the door phone will ring all indoor monitors in the designated group. This saves time from calling each device separately.

Configure SmartPlus Cloud Group Call
When the device is connected to the SmartPlus Cloud, users can configure the group call on the SmartPlus App.
Note
For users of master accounts in community projects, the SmartPlus App’s version should be 6.81.0.3(Android)/6.81.3(iOS) or higher to see the group call option.
Otherwise, ONLY the users of master accounts in single-tenant projects can configure this feature.
No number should be filled in the Group Call Number(Local) box. Otherwise, it may lead to Cloud group call failure.
Tap Me > Settings > Call Settings > Contact Preference to enter the settings page.
Select Group Call and tap Submit.
When visitors press the push button or manager button on the door phone, the group call will be made to the indoor monitors and SmartPlus App(s) in the family.
