If you are wanting to have the 'Whisper Message' (in Settings > Phone Numbers) tell you additional information before you take the call, you can include custom values in the messaging (see first image below):

Tool:  Use the 'Templates' editor to create your messaging, then copy and paste into the 'Whisper Message' field.


Here are two options you can use.  Simply paste the code into the Whisper Message field (don't inlclude the text in BOLD):

Contacts Name with Full Address:

{{contact.name}} is calling about {{contact.full_address}} 

Contacts First Name with Address Only:

{{contact.first_name}} is calling about {{contact.address1}}
