Welcome to this tutorial which will allow you to not display the number and message when you receive a message to force players to open the menu.
This is only explained for civilians, but it is simple to do it for other factions

Let's go !
For hint (message on the top right) :
In your @The_Programmer/addons/advanced_phone/client/fn_clientMessage.sqf search these lines :
Code:
hintSilent parseText format [(["STR_RECEIVE_MESSAGE_FROM_X","Max_Settings_Phone","Phone_Localization"] call theprogrammer_core_fnc_localize),_from,_msg];
Code:
hint parseText format [(["STR_RECEIVE_MESSAGE_FROM_X","Max_Settings_Phone","Phone_Localization"] call theprogrammer_core_fnc_localize),_from,_msg];
Code:
hint "You've a new message !";
For the systemChat (mesasge in the chat) :
In the same file, search this line :
Code:
systemChat format [(["STR_RECEIVE_MESSAGE_FROM_X_SYSTEMCHAT","Max_Settings_Phone","Phone_Localization"] call theprogrammer_core_fnc_localize),_from,_msg];
systemChat "You've a new message !";
.And you can do the same for the different "cases", you just have to spot hints or notifications (bis_fnc_showNotification) (if you want to do it in the different factions).
Here we go !
