Mobile number is a mandatory field when creating a CQCommand user, as this is the primary way they will be notified about a new event that requires their attention. 

There is a way around adding a mobile number if a mobile number is not applicable for any reason, i.e. you do not have the users mobile number yet. 

When entering the mobile field, simply enter in this placeholder number: "+61 (0)400 000 000". 

*NOTE* It is STRONGLY recommended the users Mobile Number is updated as soon as possible.
