I'm wondering if it's possible to add an owner property (phone number) to messages. I currently use {case.name} to reference the case name. Is there a way to reference the owner's phone number (i.e., phone number of CHV who created the case)?
a) If your cases are owned by a user (and not a location) , then phone number can be accessed using {case.owner.phone_number} . If your mobile worker's phone number is saved in any other property, then you can use {case.owner.</the name of the case property corresponding to phone number/>} .
P.S. By default case is owned by a mobile worker until and unless your application assigns the case to a location for the purpose of case-sharing
b) If your cases are owned by a location, then this may not be possible directly. For this you can save the phone number of user directly on to that case and use that case property for your SMS.
